[SOLVED]Audio stopped working at random

[vladimir1986]

Hey.

Sorry for yet another no sound post, but nothing here or another forums is working for me!

Yesterday I was using my laptop as usual, but noticed some weird audio lag. Assumed it was as I was doing an update and the CPU was working at 100%. After a while I shut down the computer (forgot I was updating and left mid compilation). Upon startup I had no sound.

Soundwise, all I can remember doing was activating "simultaeous output" in kmix. I never saw such option, and deactivating it will return just "dummy output" as sound card in pulseaudio

doing a lspci -k is quite interesting: I swear I had SND_HDA audio loaded in memory when it was compiled into the kernel, and not as a module. I just tried recomiling the kernel with it (and all the codecs) bot as a module or into the Kernel, and now it just shows nothing

I thing I installed already all the firmware I saw related with intel from diferent forums posts, but no dice.

I am just lost, I don´t even remember doing anything special with the sound and it is gone. I tried a live-USB with a different distro and got sound, so I don´t think it is hardware failure.

*Some edits:

I tried compiling the audio driver and firmware into the kernel, and also tested as modules, and combined them, but no luck. I also noticed the mic also reports "dummy output". I also tried with an old config file which worked, and same result.... might it be a bug?

Reading this post I see that I don't give much information: There are something I noticed.

My .config (no initrd to boot the kernel)

I can force load the sound driver with modprobe, so I can have "Analogue Stereo Input" in pulseaudio instead of "dummy output", but of course it won't work.

Using alsamixer: I can select HDA Intel PCH as a soundcard. Reports as Realtek ALC293, and I go all the expected controls (Master, Headphone, Speaker, PCM....) all unmuted, but moving the sliders won't do anything.

I will really appreciate any hint about where to look now, because I am totally lost.

Thanks in advance

Sorry, I don't intend to cause spam, but if anyone looks at this thread looking for answers:


Computer has no sound again. As I saw, it is actually hardware failure, so can't be simply patched with config files or installing anything. Now I get this:

dmesg|grep sound
[ 1.154985] No soundcards found.

I tried different live distros and same thing. FreeBSD, same: Sound Card can not be detected and/or interacted in any way possible. Simply put, adding to the failing I/O, I think my poor Thinkpad L570 is on its last legs. I am not sure what it has, but is slowly spreading. Sure it is not as good quality as my T43 and T60.

After yesterdays updates i have got sound issues as well. IEC958 or is it exatly that have dissapeared.
