[SOLVED] bluetooth hijacks audio

slac-in-the-box · 03-11-2023, 08:32 PM

Hello. On two pinebook pros, both with fresh installations of slackwareaarch64-15+ then updated to -current, I experienced same phenomenon:

sound was working out of both internal speakers and via headphone jack (uart switch is set to audio), and on the first laptop I paired some bluetooth speakers, and sound switched to playing through these speakers just fine. However, when I disconnect the bluetooth speakers, sound is not returned to built-in system. The levels are dancing on the mixers, but no sound comes out.

I tried to manually enable with

Code:

amixer -q -c0 cset numid=28 on &> /dev/null

but to no avail.

If I reconnect the bluetooth speakers, audio is still there.

Likewise, on the second laptop, the same phenomenon, though with some bluetooth headphones, through which I'm listening to some tunes now, but should I turn them off to use the aux cord... no audio... levels yes... sound no.

I disabled executable permission on /etc/rc.d/rc.bluetooth, rebooted, started x11, and played an audio stream. No sound. Here is syslog:

Code:

Mar 12 01:32:15 papaz pulseaudio[3244]: [pulseaudio] core-util.c: Failed to create secure directory (/run/user/1111/pulse): No such file or directory
Mar 12 03:11:05 papaz pulseaudio[1721]: [pulseaudio] module-x11-xsmp.c: ICE I/O error handler called

I looked and /run/user/1111/pulse did exist, so that's a weird error.

I also tried enabling pipewire, and got the same results of levels showing without sound. I've since reverted to default pulse-audio state.

I don't think it is hardware since sound worked originally. Any ideas on how to proceed? Is there a way to fire up alsa in debug mode?

I don't know if it's related but I have no snap,crackle,pop(audio anything) on my pbp after last updates.

alsamixer, all levels up, everything on

completes, doesn't indicate any error but there is no audio

rockpro64 audio working fine

Interesting. I may have been premature at blaming bluetooth, as both pbs went through both bluetooth pairings, as well as updating to -current. Could have been the updates.

My eldest boy also has a pbp (I trained him in the ways of slac), and he is visiting today, and reports that his audio works right after he installs slackware from the microsd; but his stops working after the first reboot, even before updating...

Well, I've rebooted both pbps as well, so I'm not ruling that out either.

The fact that slackwarearrch64-current runs the rockpro64 audio without issues may point to something hardwarish in the pbp.

This thread goes as far as suggesting removing the audio out port and suggests some replacements of known quality with an older style mechanical switching mechanism.

Also, when I ffplay an audio stream, but get no audio, I see this in the output:

Code:

[aac @ 0xffff5c31c0c0] No quantized data read for sbr_dequant.0/0

don't ask me, I've gone about diagnosing audio issues before, what I tried yesterday works today, weird

so I don't have pbp audio issues it would seem at this time

slac-in-the-box you're on your own

Hi. I installed Slackware aarch64 15.0+ on a Pinebook Pro, and initially the sound worked fine. However, the first time the machine was powered off and back on, the internal speakers no longer seemed functional.

The program alsamixer found the rockchip es8316-codec sound card, and the volume levels could be adjusted in the Headphones categories, but not in the Speakers category.

A solution, in my case, was to run the command:

Code:

alsactl restore

Nice first post, Slacro: It worked!

I copied /etc/asound.state to /var/lib/alsa/asound.state and added "alsactl restore" to /etc/rc.d/rc.local, rebooted, and I have sound again.

Thanks.
