[Q] Audio lag in android, summary - Android Q&A, Help & Troubleshooting

I've searched a lot about why there are so many better audio apps on iOS.
What I've learnt is that Android is much harder to write for. Generally we have both UI lag issues but also audio lag issues. Combine this too and we have significant problems for say, a keyboard app.
Now what I want to know is what is the source of this and can it be improved.
I remember this problem with linux years ago. Eventually we than had ALSA, jack and all the rest. There's a lot to fixing latency in linux:
1) Realtime kernel is useful
2) ALSA or Jack... Pulseaudio and AudioFlinger I'm not quite sure why we'd want one but not the other??
3) Then there's the OS itself and keeping the relevent process at a good priority... but not too high to freeze interactivity.
So what's the analog for Android? What do I even search for to find info? Keywords I can think of at the mo are only "Android realtime" or "android lag" and both of these only produce semi useufl results.
Here's some threads but they seem to be UI related which would not be fully related to the example of a beatboxing app, which could have no UI and be audio only and still lag:

update:
If interested in this try searching for "PulseAudio" and "Audioflinger". Those were the 2 keywords I was looking for...

Audio latency
I'm also very interested in this topic... I found these two links:
http://www.freedesktop.org/wiki/Software/PulseAudio/Ports/Android and
http://arunraghavan.net/2012/01/pulseaudio-vs-audioflinger-fight/
However, this seems only to work on Galaxy Nexus so far... more work has to be done for other phones
Now of course I want to have this on my Defy+ (Quarx ICS cm9) however I'm not sure if this is even possible without a custom kernel (since bootloader is locked) - but it looks like the patches are only for bionic lib, not the kernel

[Q] File browsing issues / video playback general

I'm pretty sure I am not breaking the cardinal sin of asking a stupid question with an answer right in front of me. If I am, I am truly sorry. I searched, and did not find any threads on this.
I recently modded my TP with CM7 (I'm very new to all this). Everything went fine, no issues here.
I plan to use it to play video's from time to time, pre-loaded in case there is no net at the location, etc. I use astro file manager on my phone, and since I love it, I grabbed it for the TP also. Problem is, it really seems like it cant see anything.
I am thinking the folder path mappings are off or something? I see that I can define where I want "external storage" to look, (default is... /mnt/sdcard)?
I even tried to take a screenshot and got... "Error: /mnt/sdcard/tempshot.bmp (Permission denied)" Screenshot saved to null
Anyone know what I'm missing? Thanks!
-- Ps, if I can get this sorted out, my main question was which video files are supported for playback with this CM7 rom through the TP.
These were answered before, but for the most part buried in threads. Your external SD is actually listed as EMMC and it's not in your primary directory, you actually have to go up one.
Android should play most formats it would normally, but as this is still alpha, there is no hardware video acceleration, so anything higher resolution then a internet video will most likely be choppy.
There are some video players that people have had luck with, and overclocking the processor also can help until we get hardware acceleration.

Ah ok. I was somehow able to get the stock filebrowser to see my directories without a problem after I poked around a bit. I then ran into what you already answered for me . Video's do indeed seem choppy... I think I'll try to reduce the quality of an avi I have and see how that go's.
I'm not ballsy enough to OC anything. It took me a lot of guts to flash the damn thing anyway, thanks for the heads up though.
-- figured I'd post how it turned out.
I used Xilisoft HD Converter and converted using the android specific output setting, and 640x480, runs great using double twist.

[REF] Audio Problems and Solutions

Topic: Audio Problems and Solutions
For testing purposes, I will be using CM7 as the ROM for testing; although stated throughout I have not had the audio issues others are stating unless noted why(HEAVY USAGE). Also, I will not have any MODS or Personal Hacks overlaying the out-of-box CM7! That means no zep scripts, no speedy scripts, no other personal mods other than what you get from a stock CM7 flash. No ATKs and no Memory Optimizer apps. Power Mode is set to Performance, although Power Saving has never caused issues in the past. It is IMPERATIVE that you state ANY personal MODs over any ROM that you choose to use for me to help you!
This thread is going to cover the audio issues users are having with the Droid x2. This means popping sounds, no sound, sound too loud, static noises, random mutes, etc. ANYTHING that deals with audio issues for the Droid x2!
I have had the Droid x2 since its release, and I have yet to have any of the symptoms above, let alone ANY audio issues other than random bluetooth disconnects with my car's stereo system. I isolated the issue with that and the problem has been "solved" as of me writing this. But the issues I see users having deals with audio stuttering or lagging as the user is trying to listen to music.
Now, for me to try and help you, and others I'm sure, I need you to fill out a form and post it at the beginning of your post. It should look like this:
Device: Milestone x2/Droid x2
ROM: GBP7/Eclipse/Molten/Liberty/Etc. (Also, Provide the specific version "GBP7 v.5"
Android Version: This will be kernel version, android version, etc. go to About Phone to acquire.
Audio Software: Google Music, WinAMP, PowerAMP, etc.
Audio Enhancers: DSP Manager or any of the like to change the "normal" output of the device.
Init Scripts and personal mods: Please upload the scripts and explain all mods you did that are not posted in the x2 dev section.
Sound Output: Stock Speaker, Line Out Speakers, Ear Plugs, BT Headset, BT Speakers, etc.
SD Card Info: SD Card size, how much space is used and free, and SD Class(The class is the small number in the circle of your SD card)
Symptom: What the issue is.
Then give a DETAILED description of what you problem is, what you have tried to do to solve the issue, ANY INFORMATION that you feel would be relevant to the problem, POST IT! I don't have your specific handset and I see posts of several users stating they are having issues, yet I have never experienced any of the common problems. This is not denying that the problems don't exist, but I'm trying to help, and I will need to know as much as possible.
*Try to get me average free ram and cpu usage if you can. Look up an app called seepu by Latedroid in the market, the free version should suffice.
Further Testing:
-Before trying to apply one of the fixes, try these instructions before proceeding. With some devices having issues and others not, we need to isolate the cause of this issues. This will help more with the research.
Post #33: CPU Monitoring
Possible Fixes:
DISCLAIMER: These may or may not work, you should know what you are doing before venturing too far on your own.

Device droid x2
Rom: stock rooted and still bloat
Android ver: 2.3.5 build 412 kernal 0007
Audio enhancers: none
Sound: earphones, speakers
Sdcard:16gb class 10, 4gb free
Symptom: through music player for mp3 stored on phone popping, skipping.
Solution: not really a solution but more of a way to mitigate it to a low number of times. Currently only happens about 3 times per 105ish songs on stock player.
-First be on android 2.3.5 build 412.
-V6 supercharger update 8 option 9 then option 12.
-Setcpu or init.d cpu script keep a high of 1ghz and low of 608mhz.
-get v6noop.sh and run it with script manager.
-use naven's inithack v0.6
Those steps get rid of the pop and considerably cuts the skipping down. I noticed that once the cpu falls under 608 thats when the chances of music skipping will happen. And not so much as availible ram. I had as low as 59mb free of ram with out a skip but as soon as the cpu falls under 608 the chance of skipping will happen.
This method gets a good result with stock bloated and without poweramp high buffer. Heck i needed eclipse and all that with power amp on 2.3.4 and the results still wasnt as good as it with 2.3.5. Skipped every 6-8 songs per 80 with said method on 2.3.4.
Thats why i refuse to use any rom based on 2.3.4.
Oh btw forgot to mentioned that i have my music on the phone itself since my sdcard is known to fail on me (and if it does you can't do anything really with your phone if you have sd flipflop enabled learned that the hard way).

So, is the problem still going on? If so is it every 105ish songs? Or where you providing an answer?
I'm just mentioning this as an aside, but this is my second Dx2, it's a refurb. The reason I had to do a warranty call was because the headphone jack stopped playing music probably. By this I mean that the headphone jack wouldn't play because the connection between the jack and the motherboard was faulty. Hardware failure. Well now guess what, the same thing has happened to this refurb they gave me when I called my warranty. I'm not being abusive to this phone, all I'm doing is plugging in the earphones. This is the second Dx2 I've broken in the exact same way. Honestly I think it's because the dx2 is a pos, and the abused child workers in China making this aren't putting enough saughter on the headphone jack. So now I have to sbf back to stock yet again and do a warranty call.
But yeah, I'm just complaining and telling of my experience. I don't get skips on audio very often anymore. Eclipse mostly fixed that.

I have had no issues with my headphone jack, has the phone since they came out, use headphones many times daily.
As for the skipping, one can try a faster SD card if your music is on the external SD card.
My skipping was fixed when I installed Player Pro, so I think it is an issue with the Android player itself.
Nevermind
Ignore this

I currently use PowerAMP because it has gapless playback and crossfading. I didn't see on the Android Market description that PlayerPro has gapless playback. Does it? Reason I ask is even with PowerAMP, I get the occasional skip, but not much. Just curious.
Thanks!
If I heavily multi task..I get skips....but like stated HEAVY MULTITASKING

I have the same issue with my headphone jack, any slight movement of the headphones and it turns off the music app, it's really annoying. I sent my original X2 for a refurbished one and it does the same. I pretty much gave up on that but I'm able to listen to it if i place it just right with no movement and i hold it in my jacket pocket upright.
I never get skips. No matter how hard I multitask. Frankly I'm suspicious that all of the scripts everyone runs are part of the problem. The only time I've had issues with skipping or redraws or anything memory related was running v6 or speedy. My phone ran like a hot piece of **** with speedy on stock. Well except for on startup but after about 8 hours I would need a reboot. Stock Eclipse v1.3 with the mashup build.prop has given me the best performance all around.
But I'm not an Android dev. Just a casual observer.

Sorry i was providing both. Its on going but has been subdued to that extent. When i was on 2.2.2 - 2.3.4 it skipped and popped constantly even on eclipse (up to the last one that was for 2.3.4) and the best i could get was on 6-10 songs would skip per 80 songs and popped a lot and that was using v6 supercharger and powramp high buffer. So with the method i put its all free apps and knocks it down to 3-5 songs every 105 (thats about how long one of my playlist is). With out them pops skips on almost every single song. So yes this is a mitigate solution not a permanent fix solution.
So if your phone skips constantly then try what i did and see if it helps.

This would have a factor in the skipping of music because the CPU would drop or overload at random times. I personally have never had the skips except with the heavy HEAVY multitasking like stated earier, even on stock 2.2.2 til 2.3.5. The goal here is to isolate what the user is doing while the music is playing. I'm almost positive 90% of the issues are scripts or playing texas holdem or a tegra game or something while listening to music.
I listen to music for several hours every day at work. It skips on the stock rom, Molten, Liberty, and Eclipse roms. And that's with no multitasking since I'm working and can't sit there playing with my phone. Both stored and streaming music have always skipped since I got this phone. I even tried increasing the minimum cpu speed to 600mhz like someone else suggested, but that had no affect. The only way that I have been able to stop it is with option 9 in the V6 script.

Firstly, I am envious of Pepperm1nt and others who don't experience any music stuttering, you lucky chaps. I guess you guys were really lucky to get a good bug-free phone on purchase.
I for one do experience music stuttering.
Device: Droid x2
ROM: Liberty
Android Version: 2.3.4
Audio Software: Google Music
Audio Enhancers: DSP Manager with Bass and Equalizer turned on
Sound Output: Ear phones
SD Card Info:32 GB Sandisk class 4 SD card (I also had a generic 8 GB class 4 SD card before). About 8 GB free.
Symptoms: When I listen to music, I sometimes experience music stutters. I can't remember clearly, but I think I don't get (or at least only rarely get) sound stutters when I am doing nothing on the phone. On occasion, music stutters when I turn off the display and sometimes when I am browsing the web on the phone. A couple of sure shot ways to cause music to stutter is by going into Settings>Applications>Manage Applications. This causes the Settings app to load all the currently installed apps and this takes some processing and causes a LOT of music stutters.
I also noted that music stuttering increases if I use the DSP manager settings. Also, it is worth pointing out that the amount of multitasking doesn't really matter because I experience music stuttering even on relatively mild to no multitasking..
Is it possible that there is a hardware bug on some (or many) of the Droid X2's and some people (like pepperm1nt) were just lucky to get a phone that didn't have those bugs and are not experiencing any music stuttering (or at least experiencing a lot less stuttering than others)?
Also, I was wondering if using CM7 that dragonzkiller released might help alleviate or even cure this problem? Is it possible and did someone try to check?

I haven't tried CM7 yet and I won't until it can read the external SD card, since that is where my music and my apps are at.
But, reports from people who have put it on their phones have been that the ROM is very fast. I would hope so with all the BLUR removed and it being a pure AOSP image.
But, as for now, if I don't use the V6 scripts, then my music stuttering on stock is pretty bad, even when I'm not multitasking anything. Although, I am running Juice Defender, so that might have something to do with it as well.
Still, even on my old LG Vortex (ARM6, 600mhz), music stuttering never occurred when I wasn't doing anything else on it, and then even if I was playing a game, it was rare, but it would happen.

Even I am holding back from flashing CM7 until the External SD card is working as that is where all my music and a lot of my media is. Also, I don't have so severe music stuttering issues on stock though.
Question... What personal mods have you made (anything that is not posted in the x2 Dev secton)? Also, upload your init scripts if you don't mind.Ima update the OP

It might be worth it to note that there are different versions of the droid x2. If you pull out the battery you can see it listed. It starts SJUG. Maybe some of these problems only exist on certain revisions ( I believe there are only 2 versions).
Audio codec problem
I think this is on topic relative to the nature of this thread.
I work in a corporate environment, in a manner of speaking. We use M$ Exchange for emails. We also use IP Office and voicemails are sent to email as attachments.
I cannot play the email attachment with either the standard player or with WinAmp. I can play them with RemoteWave but even then they are somewhat scratchy.
I am running a rooted stock 2.3.4 with bloat apps frozen with no addons/scripts/roms.
Previously, I had read that the codec used is the problem and that certain Android builds on ceraton devices have problems. This goes back to my initial Froyo build on this phone (acquired in Jul '10).

Go get MX video player from market
it will also have you download the armv7 coded needed to use the.player
I have had no problems...even able to view .avi and mkv files...ANY file I've come across has been viewable with this player....
Oh...and its free ..
A bit off topic lol
Now back on topic
I wonder what these different "versions" mentioned could be why there is so many different issues with not only music skips but why it seems so many issues are inconsistent here.

[YP-G1] SGP S Wifi 4.0 Best ROM for music lovers

Please refer to zaclimon's excellent all-in-one
Many people will be attracted to this device because of the sound quality delivered by the Wolfson Microelectronics WM8994 DAC. However the full potential can only be released by installing supercurio's Voodoo Sound (Google Play)
This requires root and a suitable kernel. The custom kernels referenced in the guide are all based on -SteveS-'s and will do the job.
So now to choose a ROM...
For some reason all the stock based ROM's appear to include the Beats Audio MOD (Introduced by klin1344 in R2.1 of his Klassic ROM and included by all followers). Some claim this improves the sound quality, but I would strongly disagree. Unfortunately it appears to be hard/impossible to remove.
The SGS ports have issues with camera and bluetoth and the non-stock based ROMs have their own issues which may put you off.
So that leaves us with... Stock
Don't worry, all is not lost, with a few tweaks it will work well.
First use the all-in-one to install a custom kernel and root your device.
Required apps
Voodoo Sound
Rockbox or PowerAmp
Total Commander (or any other root explorer)
Your launcher of choice (ADW free works well for me)
All your favourite apps...
Remove Music 1.1.1 and any other stock apps that you don't want.
Copy .nomedia to your music folder (for me the root of my external sd card) to avoid all your album art appearing in gallery and to make startup quicker and save your battery.
Any other alterations will be to personal taste, but you will have a great sounding player with superb battery life and everything works...

You can download the build 3.5 of ICS for the 4.0 It includes voodoo kernel module so no worries. The only problem for audiophiles though is no deep sleep and maybe lags (because of no openGL).

Thanks, I will give it a try. Lack of deep sleep is not such a huge issue - attempting to deep sleep and crashing is
A fully functioning CM9 would be great

Most ROMs have Voodoo, and you can download it anyway. What you want to check is the kernel Scheduler used by default. I've found that under some load I had noise and, rarely, lags when I was heavily multi-tasking.
I don't think there's anything that can really affect the sound quality. Has anyway seen if Samy had patched the sound driver in their stock kernel for some tweak?
actually if you read through the change log there are several versions of klins and even one or 2 of Han's ROM's where they removed beats audio because of how it broke other things, till they got a newer version of beats that didn't break it anymore.

Agreed, I jumped the gun a bit early with the ethereal Rom as i simply was flashing rom over one another and come to find out some files stayed with the conversions. With a fresh wipe and back to stock, I installed ethereal and haven't looked back - an excellent rom that eats alot less ram compared to Icy Fusion (of course nothing really touches stock in regards to ram until the ics rom comes to full fruitation). Beats doesn't even activate until you grab the driver app (which I haven't done). Using the voodoo control app instead, all is well with great battery life too!

i9100 CM 10.1 Known Issues/Bugs list

Hi
I wish to try CyanogenMod 10.1 on my Galaxy S II i9100, but i want to see the known issues or bugs first. I searched in Google for a updated list, but I only found references to the teamhacksung's web, wich is down now, also i found one list but is for 4.2.1 (not updated). Also i couldn't find it here in XDA nor CM wiki, only scattered bugs reports. Is the bugs in the list posted on the link still present? Can someone post a updated list please?
Thanks in advance.
There more than likely isn't an up to date list. It was the same with CM9. You need to either read the threads or try it out for yourself (or ask in the discussion thread if you have a specific question about something working or not).

Thanks for your answer. I know that CM have graphical problems due to lack of drivers. My interest is the camera, audio and 3d graphics (for HQ games like Asphalt 7). The camera works fully? (front/back camera, 1080p video recording, correct exposure levels) The audio works OK? (Mics, Speakerphone, No skips) Intense graphics apps and games doesn't crash?
I'll also ask in the discussion thread, thanks.
I don't use CM10 so I can't answer those questions, sorry.
Camera: poor compared to Stock Samsung Camera
Audio:Good,no prob.
Games:Asphalt 7 lags sometimes and has a low fps compared to stock Samsung
That's why I use Biftor ROM and Apolo kernel...phone was never faster.

Sound enhancements restricted in lollipop

According to xperia z3 users in xperia mobile forums, lollipop update has limited sound enhancements to movie player + walkman app and a few more playstore apps.
This is because the sound enhancement is no longer system-wide compared to kitkat.The 3rd party app developer has to include code to support sound enhancements otherwise you don't use it with third party apps.
Can any lollipop user open subway surfers, then listen to it's song for a bit and turn clearaudio+ off, return to game and see if there's any difference? I want to confirm if it's the same for us Z2 users.
I have done that in subway surfers using kitkat and it did make a difference in sound.
Bumping thread, I just need someone who's using lollipop to confirm if clearaudio+ or loudness equalazation works in subway surfers. :fingers-crossed:
This is important for me as it confirms that lollipop still enhances 3rd party apps' sounds.
Thanks in advance
I don't particularly have the game, so I can't help with confirming your query.
But I have tried it for the youtube app and found that the sound enhancement does not work. I also tried toggling clearaudio+ on and off and adjusting the equalizer while soundcloud was playing a song in the background and nothing was happening. From this I think that there is no sound enhancement present in 3rd party apps. It was not like this before when I still had kitkat.
Sorry if this doesn't help.

I requested info on that particular game because some users said enhancements didn't work for youtube in KK anyway and well it's a commonly played game :silly:
It seems like that was a false information.Enhancements work for me on youtube (on kitkat now) and appereantly it doesn't work on lollipop.
Thank you for confirming
Guess I won't be updating to lollipop until sony changes their mind on this or something worthy comes out (better camera software perhaps)

Here are more informations about this issue:

As the sony support stated this is not removed by sony its removed by android. You can call it stupid and it is indeed, but it won't change this in lollipop. There is also no plan to change this in any next releases of android.
So here is the intent every application have to implement to use a system wide equalizer:
http://developer.android.com/reference/android/media/audiofx/AudioEffect.html#ACTION_OPEN_AUDIO_EFFECT_CONTROL_SESSION
you see its not a mess for a developer of a media player to use the system equalizer. This feature was available since Android 2.3 Gingerbread, enough time for everyone.
