I have a scanner that uses an Android tablet for it's interface, and has a USB port. The USB speakers I tried using on it however don't work. They light up to show there's power going to them, and the physical volume buttons on the speakers adjust volume (as in, the volume indicator appears on-screen). But no audio is heard through any app nor System Settings.
I'm wondering if there is a way to force/enable audio over USB? The scanner is rooted.

On the 02/01 nightly CM 10.1, when I plug HDMI adapter in the volume control greys out and I am unable to affect it with the volume rocker. The sound does not work, though the picture does. The issue with no sound and no volume rocker controls persists even after adapter is unplugged until a reboot. Headphones DO work with/without adapter at all times though, and once headphones are plugged, volume rocker works again. Any thoughts?
Plugging in headphones automatically adjusts to "safe" level. I hate this. Is there a mod (Xposed?) that prevents the volume from resetting? I'm not talking about the toast/pop-up about unsafe volume levels being dangerous (I've disabled that with Wanam). The devices I'm using are the Samsung Galaxy Light and LG 8.3 G Pad, both running 4.2.2, but I'm pretty sure it's a universal thing and the actual devices don't matter.
Looks like this might do the trick: https://play.google.com/store/apps/details?id=com.jakebasile.android.hearingsaver
"- Plugged/Unplugged Sliders - These control the volume that will be set when the headset is plugged in or unplugged, respectively. The volume that these refer to is indicated by the Radio buttons at the top."
That combined with the Xposed mod to disable the toasts will be an easy work around.

I'm giving it a try, thanks. Seems to be working.
Just bought an Xperia Z Tablet and note that the volume seems low.
When I go to the Settings/Sound/Volumes I see the button on the first Volumes selector ie Music video games & other media is about half way across.
I slide it all the way and press OK but when I go back in it has reset itself to the half way marker?
I am using blue tooth headphones while this is happening.
Any ideas why or how to boost the volume?
OK, just plugged in some conventtional headphones and when turning the volume up got the warning message. This didn't appear with the bluetooth headset so the system limited the volume. Once I had set OK in conventional headphone mode it seemed to clear the way for full volume in bluetooth mode. Volume is fine now.
Hello guyz !
Today I have a question related both on software and hardware.
I have found limited edition headphones for some cyon phone (korea).
They are shiny red, have old multi (21pin) connector plug but I checked that they only use 4 wires.
I got 7 buttons (PREV, NEXT, PLAY/PAUSE, STOP, CALL/END, VOL+, VOL-), microphone and also TRS jack on top.
I've connected only theadphones (short cable ended with TRS jack) to my phone and they sound fantastic.
The question is can I get all of this buttons working or most of them ?
I know how to get vol+, vol- and call buttons, just need to change resistors values but I want more.
Most devices uses only 3 buttons with volume or next/prev track + call.
I've found this but here
HTML:
https://source.android.com/devices/accessories/headset/specification.html
are only 4 buttons.
Is it controlled only by hardware (resistors gives specific voltage) or it can be programmed via software ?
The Samsung Galaxy S21 got rid of the phone jack from previous models and now has only a USB-C connection. I bought a USB-C-to-phonejack converter so I could use the headphones I had from my S7 phone. It works when I am using the headphones to listen to music or watch videos. By "works" I mean not only do I hear sound through them, but I can control the volume either using the phones controls or the built-in controls on the headphones. EXCEPT! Except when on a phone call. When I use the headphones when using the phone, the volume control does nothing. Neither the controls on the phone itself, or the controls on the headphones. I end up deafened because the volume is at max and can't be turned down. Again, this is only while speaking on the phone; other apps let me use the volume controls.
Any ideas on ways to fix this?
Thank you,
S.

I can't guarantee that this will work. But often what seems obvious to me is something other people miss completely. (And the other way around too.)
When you press the volume down or up rocker on the phone, have you noticed the three horizontal dots at the top of the onscreen volume indicator? If you tap on that 3-dot menu, multiple vertical volume indicators appear. I haven't tested with a USB-C audio jack dongle but I am betting that if you have the dongle plugged in (regardless of whether the earphones are plugged into the dongle), one of those vertical volume sliders will be specifically for the dongle/USB-C output.
Give this a try and let us know if this works. If it does, I realize this might be annoying to do every time. But maybe then you can find a utility in the Play store that allows you to set individual volume levels.
Good luck.
P.S. I fully understand if you prefer the wired earphones. But I can tell you that when I use bluetooth earphones of various kinds, simply pressing the volume rocker does reduce/increase phone call volume.

Thank you. I never really noticed those dots in the volume control; just ignored them all this time! I pressed them and see the extra options. I haven't tried the USB-C dongle yet... I just packed it away for a trip this week. I'll keep it in mind though and try it as soon as I unpack.
