Sound

[mylo]

Hallo,

mit dem cli-installer habe ich die aktuelle iso installiert. Sound ist  nicht vorhanden und kann auch nicht via kmix oder alsamixer herausgelockt werden.

What to do?

[towo]

echo options snd_hda_intel index=1 > /etc/modprobe.d/mysound.conf

könnte helfen. Danach rebooten.

[mylo]

Thanks towo, it did not help. I also tested all the devices listed, but none gave a sound. Other idea where to search?

[sunrat]

Both cards use snd-hda-intel so this is tricky. You need to get HDA Intel PCH to be card0.

Try this. Create a file /etc/asound.conf and put this in it:

Code: [Select]

pcm.!default {
   type plug
   slave.pcm {
     @func getenv
     vars [ ALSAPCM ]
     default "hw:HDA Intel PCH"
   }
 }
And if that doesn't work, try adding to /etc/modprobe.d/alsa-base.conf -

Code: [Select]

options snd-hda-intel enable=0,1
Google Translate:
Beide Karten verwenden snd-hda-intel so ist dies schwierig. Sie benötigen den HDA Intel PCH card0 zu sein.

Versuchen Sie dieses. Erstellen Sie eine Datei /etc/asound.conf und legte diese in ihm:

Code: [Select]

pcm.!default {
   type plug
   slave.pcm {
     @func getenv
     vars [ ALSAPCM ]
     default "hw:HDA Intel PCH"
   }
 }

Und wenn das nicht funktioniert, versuchen Sie, die Datei /etc/modprobe.d/alsa-base.conf -

Code: [Select]

options snd-hda-intel enable=0,1

Hi sunrat, I made a screenshot from the audio devices in the systemsettings (attached). However, I do not have a separate soundcard, just the onboard sound (or at least I did not pay for an extra one). So may be, I can just delete some of the entries in the table?

I'll try your hints and report back later.

[sunrat]

Click on the one marked "Default Audio Device" and move it to the top. This was sufficient to get all my audio players working, but not for Flash in Iceweasel. For that I had to edit alsa-base.conf.
The goal is to make the device show as card 0 in aplay -l (that's a small letter "L" ) and cat /proc/asound/cards.

[mylo]

Hi, both hints did not work. I try the move tonight (office awaits me).
Thanks first!

[sunrat]

You do need to reboot after editing the config file.

[mylo]

Hi sunrat,

I rebooted, but could not here anything after.
I started a console, started alsamixer and played around. At first, with no success. Although then, I found an interesting phenomena, which I try to explain here after.

I talk about the first, the third and fourth setting in aösamixer, named

1 - Master
3 - PCM
4 - Front.

I set up Master to a preset below the red one. Nothing.
I tried 3 and 4 the same. Nothing.

Then I set Master to 100% red and had a very very little volume, when opening the volume at the speakers to 100%.

And, and and..at the end:

At the end I found out:

The signal lined out to the speakers is an addition of all three presets on Master, PCI and Front. I set up all short below red and my speaker provides normal volume at normal preset.

Questions to this welcome. Hope this helps other, as alsamixer presets semm to be too low.

sunrat, thanks for leading to a solution!

[sunrat]

Good you got it working!
I discounted that simple solution as you said you had set volumes in alsamixer in first post. It is usually the first suggestion I would make.
