Sound stopped working in Laptop with Mageia Linux


Hello,

I have Mageia 1 installed in a new Toshiba notebook of this model:

toshiba satellite L750 12Z
http://ce.computers.toshiba-europe.c...UCT_ID=1112775

I had some issues with the headphone sound previously but it was fixed, the problem description and solution can be seen here: http://www.linuxquestions.org/questi...tebook-932462/

So basically the problem is that the sound was working fine everywhere and then now it completely stopped working. It is my wife's notebook, and she has no idea what happened between the last time that the sound worked and when it stopped working... so basically I am lost at how to fix this issue. Any ideas?

Here the output of lspci:

[kasia@localhost ~]$ lspci

09:00.0 Ethernet controller: Atheros Communications AR8152 v2.0 Fast Ethernet (rev c1)

Everything is on in alsamixer.

There is no sound both with headphones and without.

I tried to rename /etc/modprobe.d/alsa-base.conf to /etc/modprobe.d/bk-alsa-base.conf to deactivate it (will that actually deactivate it? Maybe not...) but it made no difference.

thanks,

Felipe

Try aplay -l first to see which audiocard is first, nvidia-hdmi also presents itself as an intel-hda sound device, if nvidia goes as first device you need to swap it in your .asoundrc file in your home directory

Hi sekelsenmat, Have there been any updates installed? Did you read the alsa-base.conf file to see if your original edits are still there?

Good luck. ;-)

An update was my first suspect, but my wife said she does not remember if there was any. Yes, the file was still there unmodified. Now I moved it to my home, to be like before my changes, but it didn't help.

For sure it is not a hardware issue because this computer has dual boot and in Windows the sound works normally.

Ha! I found a way to make it work =)

I think that there was no update. I simply had to make a full format of / and reinstall when I was trying to solve a display issue and my solution went wrong. So probably I forgot to rerun "alsaconf" after the full reinstall and my wife didnt notice the issue until she needed sound now.

"alsaconf" was one of the first things I though about, but it confused me the fact that it didn't exist in this computer now (because of the fresh reinstall). So I installed alsaconf with "urpmi alsaconf" and executed it and like magic the sound works =)

thanks everyone
