[SOLVED] Sound through speakers stops working on Stretch, headphones work

Hi all.

I just installed Debian Stretch on an Acer Aspire E1. After a few minutes into a session sound stops comming out from the laptop speakers, although it plays over headphones or external speakers (connected through 3.5mm port). I've noticed it happens when changing the volume of a youtube or other site video. Last time it happend I ran dmesg and noticed this:

Jun  3 17:58:13 sophus kernel: [ 2042.987363] perf interrupt took too long (2592 > 2500), lowering kernel.perf_event_max_sample_rate to 50000

I don't know if it is related.

My soundcard:

lspci|grep -i audio
00:01.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Wrestler HDMI Audio
00:14.2 Audio device: Advanced Micro Devices, Inc. [AMD] FCH Azalia Controller (rev 01)

My kernel is 4.5.0-2-amd64. Any ideas?

Have you read https://wiki.debian.org/Sound ?

I have now. It was very enlightening but not particularly useful. I know now that the problem probably stems from PulseAudio, so the real question is how I diagnose it.

Update on this (hopefully someone has experienced this as well): audio through speakers goes mute after 5 minutes or so of playing simultaneously a flash/html5 video on firefox and an mp3 file on totem. I still get both streams on headphones. There is nothing useful on any of the files in /var/log. Any ideas of how to diagnose/solve this?

EDIT: here's the contents of /etc/pulse/client.conf:

I notice that the default input and output have no value and are commented. I tried running /usr/lib/pulseaudio/pulse/gconf-helper and I got this:

(process:1687): GConf-WARNING **: Client failed to connect to the D-BUS daemon:
Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

and nothing else happend except the PS1 turned into a ! as if expecting something; I had to Ctrl+C to get back to the terminal. I have been trying to make speakers work again by restarting both alsa and pulseaudio from the terminal to no avail. Any ideas?? Please help, it's rather annoying. Thanks in advance.

Hi, I have the same problem with stopping sound from speakers and the same message in syslog (haven't checked with headphones though).
Running on ubuntu 16-04.

AdbekunkusMX, have you found a solution to this? Thanks for any input.

Hi. Sorry for the delay.

I quite frankly don't remember how I solved this issue (or if I solved it, for that matter); that box is long gone.

However I did experience a quite similar problem on my current laptop (Dell Inspiron 5667 with Intel sound card) and the following steps solved it:

1. Install libsamplerate0.
2. Uncomment the following lines in /etc/pulse/daemon.conf:

allow-module-loading
resample method =
avoid-resampling

3. Set "resample-method ="; I used "src-sinc-best-quality". The whole list of options is here: http://www.mega-nerd.com/SRC/faq.html
4. Create /etc/modprobe.d/alsa.conf with the following contents:

options snd-hda-intel model=headset-mic

(I can't quite remember exactly what this does, to be honest).
5. PROFIT!!

Hope it works for you. Cheers!

Hi, thanks for a hint.

I have tried that but unfortunately it doesn't help.

Meantime I have noticed that my wireless connection also drops at the same time as the sound. And it is always accompanied with the message in syslog

perf interrupt took too long (2592 > 2500), lowering kernel.perf_event_max_sample_rate to 50000

Moreover, my CD-ROM opens randomly. Even though there is no medium inserted and I don't use any program that shall open it.

Probably I will try a fresh reinstall of the system...

There's a weird thing if the sound is muted in totem, it's muted globally, and nothing will unmute it but going into totem and raising the volume.

I had been having the same issue (sound through headphone jack but not speakers). The solution posted by AdbekunkusMX, to use libsamplerate0, worked for me. My daemon.conf file didn't have the line 'avoid-resampling' so I added it.

Thanks very much!

I'm glad it worked for you; I'm now marking the tread as solved.
