Anyone else have issues using DSP Manager at high volumes? The issue happens when using the phone speaker or headphone jack (didn't test bluetooth) and setting volume to ~85% or higher. The resulting sound is a lot of high pitch squealing that I imagine would be similar to what you would hear with a decoder issue.
To replicate the issue:
1) Launch DSP Manager, choose Headset (if you choose headset, I wouldn't put your headphones on for this test...or if you're running a line out to a stereo receiver, turn your volume all the way down) or Phone Speaker and disable all effects or select Menu, Reset.
2) Play any mp3 or streaming audio (ie Slacker, Pandora), adjust the volume to be within 1-4 clicks of max.
3) Go back to DSP Manager, enable Equalizer, and then adjust the low frequency slider (leftmost slider) to be above 0.
4) At this point, the sound issue should be noticeable if you're experiencing the same issue I am.
If someone can please test this and confirm they have the same issue I would appreciate it. I didn't find any other reports of this issue, but if it's a known problem, can someone please point me in the right direction to resolve the issue? I've tried this on 4 different ROMs (I think they may all be Cyanogen based) and I have the same problem with all of them.
Thanks in advance for any input.
Sorry man I couldn't replicate it on Nonsensikal 8.8. Used Pandora, set volume to within 2 clicks of max, and set <100 hz to .2 .4 and .6. Didn't get any kind of squealing. This was on phone speaker. I have had weird DSP issues in the past though. Just didn't care enough to try it on all the froyo roms.

I have the same exact problem. I cant even move anything without it going crazy. im running CELBFROYO 2.9
Thanks for your feedback guys, I'm going to try out Nonsensikal 8.8, will report back later.
Edit: I tried Nonsensikal 8.8 and still had the audio issues. Did a little research and I thought maybe I was experiencing "clipping". I don't consider myself an audiophile so I wasn't really sure if this was an accurate diagnosis of my issue. This lead me down the path to try out the Mixzing app since it has a built in EQ. Since the Mixzing EQ only functions on audio thru the Mixzing player, it's not an end-all solution since I find myself pulling up Slacker when I want a change of pace from the mp3s I have on my SD card, and the Mixzing EQ does not function for streaming music.
Anyway, I found the EQ in Mixzing to be quite helpful as it appears to actually detect when clipping is occurring and notifies you by change the EQ bands to red. The clipping I experienced thru Mixzing is not comparable to what I hear when using DSPManager. The Mixzing clipping results in the audio cutting out for a given frequency range - for example when clipping occurs when a bass drum is playing, you don't hear the full range of sound of the bass drum, the low frequency is cut off. What's also noteworthy here is that thru Mixzing, I was able to rectify the clipping issue by simply re-adjusting the sliders to their previous positions and the sound output was corrected. Whereas with DSPManager, resetting the sliders didn't fully resolve the audio issue, I was still able to discern a high pitch whine especially during quiet portions of a song until either the song ended, or I disabled the EQ. If this were related to a clipping issue, I presume the squealing I hear would go away when I reset the sliders to their previous positions, since the squealing persists, I think it's probably a decoder issue.
Something else I learned here, perhaps already evident to other users, is that for each frequency band you adjust in Mixzing, it requires additional processor resources. This might explain why the Eris (not sure if this plagues other phones) struggles here. And on that note, I was using my Eris to test the waters and help me determine if it's worth rooting and dropping a custom ROM on my Incredible. Since this sounds like it can potentially be a resource issue, and I haven't found other users on different phones experiencing this issue, I guess I'll take the plunge and try a custom ROM on my Incredible.

Has anyone else experience the same problem where their music would not play smoothly anymore Neutrino v2.0 and v2.1(p)? My music played just fine on v1.4.
I'm using powerAMP and I've already tried increasing the audio buffer and the audio thread priority and neither is fixing the problem. This happens both from the speaker and through the headphone.
I saw a post about this in the main dev thread no one else seemed to have followed up on it =(.

I think it has something to do with the 'Media step' mod, which I deleted from V2.0 onwards so it shouldn't be a problem...
Can you describe in more detail what happens?
The phone runs very smooth in all other aspects, but the audio would hiccup...as if I was listening to CDs that were scratched.
I have had the same experience. I have tried different music programs so it's not app-specific. I've also flashed a different kernel to see if that could be the problem.
I have noticed I do not get the same bugs as on different cm7 ROMs where the speaker wouldn't work at all after unplugging from the car dock so the trade-off's been worth it.
I only experiance this when the phone switches from 3g to H. And the slipping becomes extremely bad when I lose service for a bit. If I go to networks and select 2g only, it seems to somewhat fix it. Until I drop service. Used several different radios with the same result
I'm going a hunch that the tweak to the windowsmgr.max_events_per_sec in the build.prop is somehow interfering - I've edited mine from 150 to 50 and I think it sounds smoother on the speaker but that could just be deceiving. I'll update after I've used it in the car dock on my way home.
-Update-
To I'm sure no one's surprise, this did not work. Music still pops. Maybe once or twice every thirty seconds.
I just tried playing music in airplane mode and the music doesn't skip either with Wi-fi on or off.
Is this problem only with PowerAmp? Does it work fine with other music players?

Every music player. Stock, double twist, poweramp etc. I have tried them all.
Confirmed for me with every music player, not just with powerAMP.
TTT Any fix yet?
I've been looking into this over the weekend. It happens on all media players I've tested:
DoubleTwist
WinAmp
PowerAMP
Stock
Sometimes it is so subtle that you wouldn't noticed if you didn't literally have every nuance of a song memorized. I took logcat logs and marked every "skip" I heard, while playing video games with my headphones on for a few hours this weekend, but nothing stuck out of the logs.
This issue is not in 1.4S, but was in 2.0, 2.1, and still in 2.1P. Sorry I don't have any other useful info.

Will yours skip if in airplane mode? Mine doesn't.
mine actually skips in airplane mode aswell, but rarely...
See if it skips in V2.2...
Bad news...the audio still skips. I'm seeing that it happens often especially when there are changes in reception, like when it's switching between h+ and 3g...
I can happily confirm that setting SeCPU profiles to sleep at max and min @ 456mhz fixes the skipping.
Hmmm, I thought that would hinder the battery saving effects of clocking down. I've been clocking the CPU down to around 216-312 Mhz when my phone is idled.
Usually I'm playing audio on the phone when I'm driving and I have the phone plugged in to the car charger, I'll try to increase the min clock for when the phone is charging and report back.
I don't know if it's worth mentioning again, but with the same setting I have now in V1.4, the audio doesn't skip at all. I'll also test if this is happening with weekly #6 as well.
I realize this is a bit off topic, but seeing as how my issue is audio related I figured I'd give it a shot.
In short, my internal speaker is going in and out. There's no specific instances I'm seeing, but I can say I notice it most when it goes out during a phone call. A couple of times I've noticed a bit of a raspy sound, kind of like a loose speaker wire or skipping cd would make (which leads me to think it's the speaker itself).
That being said, if anyone else is having this issue I'd like to help out as best I can.
I'm on 2.2, btw. Currently running 100% EE, with the CM7 provided Google Apps.
Thanks for the help, and sorry for the intrusion.
Hey Guys,
I have a GT-P7510 running CM9 with Pershoot's 2.6.36.4 cyanogenmod+root kernel
I use Spotify and PlayerPro to play my music.
I have noticed Voodoo Sound has been acting rather strange.
I've noticed on my Vibrant that Voodoo Sound once started after boot and set, will keep its volume until reboot without fail, provided the proper settings. but for some reason on the tablet it is unable to do that. Spotify suffers the most from this, after almost every song it decides to drop back down to -10db from +2db where I have it set for lineout in my car. If I open Voodoo Sound up after the volume drops, it will jump back up either immediately, or after I press on 'Headphone amplifier' when the bar comes up, it resets the volume back to +2db for the duration of that song. With my Vibrant, that behavior does not seem to exist. I've been trying to figure out what could be causing it.
My guesses are:
Spotify is messing with the settings between each song
CM9 Memory Management doesn't keep Voodoo Sound running as a service
Android Gremlins
Anybody else notice this behavior? If so, have any suggestions to resolve it, or to resolve my suspected reasons?
Thanks!
-Rob
I've been having the same issues aswell, I reported this issue already to curio but then again has unticking the box for safe level audio made a difference?
yeah, jack safety is off. I fiddled with it again last night. There is a good chance we will have to talk to notify about it. I have been noticing that their software is very buggy on this platform.
Rumor has it Samsung and CM are collaborating, which might give us the extra leverage needed to have them fix these bugs, of these are their bugs.

I had a bit of a breakthrough. I was researching spotify and volume related issues. I came across people complaining about how spotify handles sound, which is a bit like what Skype does to media during an incoming call, as well as some people's dislike for it. A little more digging came across this thread on xda. http://forum.xda-developers.com/showthread.php?t=803432 a chap with windows mobile had that problem and follow the m.spotify.com link, download for android 1.6+ install it (3rd party install apks enabled) this one. Once done confirm the following voodoo sound settings.
Smart amplifier
Don't interrupt music
Restore at launch
Load up spotify
Drop the volume until analog volume drops
Raise it back up again.
It held it for at least 3 songs while spotify holds focus. If you leave focus it will drop at the end of the song.
Beats having to turn the gain on the car up dangerously high and having alternator noise bleed in. Also beats resetting the volume after each song.
Fortunately with smart amplifier running you can just drop the volume a couple of times and raise it again for it to hit +2db again rather than diving through menus. And I was wrong, it defaults to -4db after each song.
Oh well its a lazy but annoying work around for now.

Hey Guys,
I have a little bit of an update,
The new preview release of spotify doesn't seem to be as heavily effected as the current market release, so if you use spotify and this is driving you crazy. Google their latest beta preview, should be easy to find. Perks of the new version, faster, less retarded navigation, full ics support, 320kbps, and just straight up better [=
Only draw backs atm is it is portrait mode only and occasionally drops the voodoo sound volume.

Trying to determine if this is a software bug or a hardware problem. Looking for some additional people to test and verify.
ISSUE:
While listening to music, I hear a periodic, short duration, low-volume burst of static. This only happens when WiFi is on but not connected (searching for network to join). This also only happens with headphones (at least I have not been able to hear it over bluetooth).
NOTES:
I have tried both the HTC stock music app to listen to music stored on the external SD card and Google Play Music to stream data from the cloud.
The period of the noise is 15 seconds when on a Jelly Bean ROM (I have tried both MeanBean and xHausx's stock ROM. When I was on MeanROM ICS, the period appeared to be 17 seconds.
The duration of the noise is 1/4 second or less.
The volume of the noise is very low. I recommend trying to reproduce the problem with very quiet music.
Wifi must be on and scanning to hear the noise. With Jelly Bean, the WiFi scanning interval appears to be 15 seconds (I did not check the scanning interval when on ICS). I recommend not being near a network that you can connect to when testing this.
I am S-OFF with the original LazyPanda HBOOT (1.12.2222) with the latest firmware installed from xHausx's thread.
BACKGROUND:
Here are some posts where this issue has been discussed in other threads:
JustinChase's first post regarding the issue in the MeanROM ICS Thread
Follow up later in the thread: #1, #2
Continuing discussion in MeanBean thread​
Thanks in advance for any testing you can do!
I have the same exact problem even connected to WiFi. As long as I have WiFi turned on I can reproduce the static noises you speak of on both stock rooted 4.1 and meanbean roms. S-off also :/
Sent from my EVO using Tapatalk 2
I also have the issue, but only when wifi is turned on, but not connected to a network. If I have no network remembered (nothing for it to try to connect to), I don't hear the problem then.
The noise is a static, crackling noise, which sounds like 'machine noise' that I also hear when I'm listening to my desktop computer with headphones thru the crappy motherboard connections. On the desktop, whenever I move the mouse wheel, or put the system under load, I hear 'machine noise' thru the headphones, likely related to poorly designed/shielded onboard audio.
This makes me think if might be hardware related, but the fact that it only happens when wifi is trying to connect to a remembered network makes me think it's software related.
The noise is always the same volume, which isn't very loud. If you listen to your music at 1/2 or higher volume, you will likely not hear it, but if you listen at about 1/4 volume, or lower, it's a pretty loud and very annoying noise. I almost always hear it at the end of a song, but hear it throughout songs also.
I'm s-off, so don't really want to go complaining to Sprint about it yet, but since it seems only a few other people have reported the same issue, I suspect it might by phone specific.
I would really appreciate anyone/everyone testing this and providing feedback, even if it's 'I don't hear this, you're crazy', at least I'd know
To test, make sure that you have a wifi network remembered on the phone, go to a place where wifi cannot connect to the network (or any other network), then play music with the stock music app (the red musical note icon), make sure the volume is less than 1/3 and you should hear this noise within a minute or 2. Some have reported every 15 seconds, but I'm not sure I hear it quite that often. If you make it thru 2 songs with no noise, you probably don't suffer.
Thanks, looking forward to some feedback
Hmm... Very odd. I might have a little input or it may be completely unrelated.
Are you guys with this issue using PowerAmp music player (i use that, it is AMAZING).
Anyway, I noticed that while using any global beats addins, I usually get a weird staticky noise through my headphones... BUT, this only happens while playing a song and another sound comes up. In example, I am playing an MP3, and I get a text message, or a low battery warning. When the other sounds come into play, it disrupts the music playing, and the notification doesn't even make its sound; just the static interruption where the sound WOULD have been. A fix for this, is to enable [maybe disable? not sure which is the default setting, but just uncheck/check depending if its on or not] the Direct Volume Control option. Doing this allows me to hear the other sounds while playing the music with no interruption.
Now, to get on board with the OP who has this problem on WiFi only. Perhaps it is the same scenario as myself. Maybe your WiFi is giving some sort of SU notice from the makesh that the WiFi mod asks root for.
Sorry if it sounds a bit confusing... But hope it helps!
EDIT: After reading some posts above, I see the problem comes in even with the stock music player. Idk, I still think it has something to do with MusicBox/DSPManager/Volume+ and the WiFi SU notices

That could be a bad port... Or it may be an IRQ problem If you feel comfortable playing with your BIOS on the PC, look into your IRQ settings
Some new info:
I clean installed MeanBean 0.6, connected to my home WiFi, then went to work this morning. Now that I'm at work (and not connected to my home network), the period of the noise is back at 17 seconds. I went to the WiFi settings and deleted my home network settings. Now the noise is at 15 second intervals. The volume of the noise also seems quieter.
I connected to my work's WiFi (they are finally letting "non-corporate controlled devices" connect to the network) and the noise is gone.
I'll have to wait until after work to retest the interval with a remembered network present.
Yesterday, when testing with a stock ROM, I only tested when I had never connected to a network before. So the period may not be ROM or OS version specific.

I don't see the makesh app looking for root when on a Jelly Bean ROM (it doesn't show up in the SuperSU logs either). I wonder if HTC changed that in the 3.15 update.

Where might I find this setting you refer to? As you noticed (after you wrote this), I'm only using the stock music application, and can't find this setting anywere. I suspect it's in the PowerAmp player, but wanted to verify, so that I can try adjusting it. FWIW, I do hear the quiet notification noise while the music is playing (which used to stop the music on ICS - this is MUCH better).

I'd like to 'fix' this issue also, but it's been a LONG time since I've worried about IRQ issues. Windows 7 (and XP?) deals with IRQ issues well, so I haven't seen any conflicts in years. What in the BIOS might I be looking for, and how might I adjust it to try to eliminate this issue? I'm plenty comfortable in the BIOS, but the only IRQ settings I remember are related to forcing it to use a specific IRQ, but wouldn't know what to try changing for positive effect.
I'm plugging into the front audio port of the machine, which connects to the motherboard via a HD audio connector (if I remember correctly). I believe I have the same noise issue when connecting to the audio out on the back of the machine, which is directly connected/part of the motherboard. In fact, I've heard these 'machine noises' on all of my machines for years, so just always assumed it was a symptom of the lower quality audio connections. However, I'd LOVE to eliminate this issue also, if possible.
Sorry for the off topic
This sounds like it's just poor shielding somewhere. I believe the wifi antenna is near the headphone jack so it's probably causing some interference there.
Exactly Haus. Try different headphones or speakers. You could for your headphones get THIS then run a couple of wraps around it through the center near the phone jack, and see if that helps. For speakers the signal could be coming in from many places (power input, signal input, with in audio amp, or the speakers themselves. Now if the sound is coming from the speaker inside the phone.. Well you have much bigger problems than a ROM.
I have the static issue when streaming over Bluetooth with the screen on, wifi on or off, on both stock and custom roms. Turn the screen off, no static. Also, Bluetooth disconnects at random if I leave the screen on and will not reconnect until I unpair and repair with my stereo.
It has to be an issue with jb, as I've never had this issue until the update. Fwiw I'm thinking connections optimizer (on or off) has a hand in this issue.
Think I'm having this too
I was noticing this today on wifi. It would make a crrrik like a cog sound every so often, at first i thought it was the song, then when it did it on the next two I found this thread. It was not just 1x 2x per song it was almost on beat at times. I heard it probably 30 times in 30 second song. Another thought was some file/notification was making the sound in the background.
Turning wifi off so far has resolved problem. It was really annoying. I don't think its an antennae issue since its the same noise each time exactly (including duration) about a .25sec noise. Thinking of antennae interference its usually a scratchy sound that is intermittent duration some long some short etc.
It was extremely unbearable as I listen to the lowest setting on the phone with beats off.
Hello all,
I am experiencing a very weird volume issue. I'm debating sending the phone in for the insurance, but I heard that this phone has stopped being sent back as a replacement, my buddy with the same one had to pick a different one. So I would like to find a workaround
Problem:
The volume is inconsistent, very much so, but only at very intermittent times, sometimes frequently. It starts at one of the two levels, low and high, and switches between the two sometimes 5 times in a few min or once every few day. it occurs across every application and every re-install of the venom rom.
It is a problem because 1. it is annoying, and 2.I have a very loud sound system in my car.
Normal loud listening volume is around 20-23 out of 35. i can turn it all the way up with no distortion and it is extremely loud at this point, loud enough to damage ears easily. When I turn it up that loud(at festivals) I like to wear earplugs in it. When I'm just driving I don't need it that loud, but I always ride to taste with the volume. Sometimes i don't look at the volume level on my car, the volume on my phone is up all the way but it has decided to take a low level to start today. While driving and not looking at the volume, just listening to it, i will usually set my volume at 33-35, then the phone decides to jump to it's loud setting making me cringe and swerve in pain and surprise as I sound like a rattling venue driving around. I have mostly solved this by just using my ipod. But I really like having spotify and pandora in there. plus android kicks ass, my ipod feels like a backup hard drive in it's waterproof case
Have Tried:
Pushing volume button up(does nothing when low)
Rebooting
Re-installing os
Bluetooth vs aux (both same problem)
resetting Bluetooth connection
removing and and pushing in headphones
placing a call
Guess:
it appears to not affect calls or ringer volume, just media volume, even speakerphone is unaffected. my guess is something in the audio processing section due to it affecting bluetooth and aux out. I have ruled out speaker, installed programs, connection type, time of day, specific mp3's, temperature, movement and what i'm doing on it. It is really stumping me, usually I can figure out what is broken on the inside of things hardware related, but I don't know the inner workings of this phone exactly.
Would like:
To know what is actually going on. A fix would be awesome, but I mainly want to know what it could possibly be. It has confused me for too long.
To know if the phone can be replaced for the same model to hold out until next summer
Would not like:
To be told to just get a new phone. I like this one and the rom on it. plus i already paid for it and a new battery. i will live with the issue until next summer if need be
Any ideas?
Which media player are you using? Since it only occurs during media playback perhaps a different media player will give you some insight

I usually use power amp.
Though the problem occurs across that, the stock media player, Pandora, spotify, youtube, flash videos. pretty much everything except for calls and ringer.
Try using a app that (re)sets the volume every time you connect to the radio via Bluetooth. I use a car dock that automatically launches my car app (car home ultra) when the phone is inserted, and the app then automatically sets the Bluetooth media volume to a preset volume every time.

Hi everyone, as stupid as it sounds, after many years of using android I just noticed that using equalizers ( and i've tried many of them ) causes the volume to drop. I have discovered that this is standard behaviour since android lowers everything by -6dB to avoid clipping when setting frequencies to +6dB.
Since my phone can't really drive my headphones much, is there a way to bypass this behaviour without using apps or rooting the phone?
Note that the maximum Volume is limited by the hardware. So the only way to have equalizing at maximum Volume is to lower the overall volume. You may be able to work around this by using an audio player that ships its own audio library or has an amplification function. Maybe BlackPlayer works. Note that this will only change the behavior of the music player and that you may experience clipping.
If you want to do changes for all apps there is no way around a custom kernel (or rooting at least) that I am aware of.
The thing is that the stock presets inclued for example in my JBL Headphones app work fine, but as soon as i try to modify one of them the volume drops. This is true for other equalizers too, for example the stock samsung one. It has something to do with how the personalization is handled i guess.
I am currently using a rooted phone with MyAndroidTools to check inside the databases to see if i can find something to tweak but no luck so far.
