[solved] No sound through laptop speakers

Unread post by ivanovnegro » Fri Oct 02, 2015 7:38 pm

I caught a strange problems. I played with some kernels and from nowhere I lost sound through my laptop speakers. I only get sound through headphones or external speakers. Alsamixer shows everything normal, nothing muted.
It could be the kernel change but even when I get back to a previous one, the sound is not coming back. Now it does not matter which kernel.

Of course, no Pulse here:

After booting normally the machine does a crack sound and I know the sound card was activated, that does not happen anymore.

Do you get sound with another spin (even a live spin run from USB)? If you do, take a look at /etc/modprobe.d/alsa-base.conf and see if there is any difference between the version that works and the one that does not.

Also, do you have a ~/.asoundrc file?

On this machine I cannot test another spin. It does not boot from USB and there is also no CD drive. It is the old rig running Debian sid as usual.
No, no .asoundrc file here.

I have no /etc/modprobe.d/alsa-base.conf. Is that normal?

Sorry, I don't really have anything useful then. Every time I have had a sound problem like this it was because something was configured incorrectly in alsa-base.conf (like this one.) Sound is pretty much a mystery to me, so I just mess with stuff until it starts working again.

Did just that. Reloaded the alsa modules. Fuck. I do not even remember what was the actual fix. I was too busy reading the Arch Wiki to solve sound issues.
Sound works perfectly through speakers.

I let the thread open till tomorrow.

how about

Code: Select all

grep pcspkr /etc/modprobe*/*
there should be one or more blacklist.conf file, one may contain the line

Code: Select all

blacklist pcspkr
Remove it and reboot.

I had exactly the opposite problem: Toshiba Dynabook SS1 defaults to *use* PC speakers even they are blacklisted, I had to use alsamixer to mute the speakers (the beep is rather disturbing in public places)
..gnutella..

It is OK, sound works normally and I have the cracking sound at boot again.
