 |
|
Hello,
my sound card is working, except for the microphone. The strangest thing is, that I can not declare "Mic" to be a "Capture Device", i.e. in alsamixer "Mic" is shown as a Playback device not as a "Capture" device and it also doesn't have a possiblity to be selected as "Capture" device, i.e. you cannot press spacebar in alsamixer to select it.
Do you have any ideas what my problem. Is the above thing my problem, or is that even no problem?
Do I have to use a line like
options snd-hda-intel model="laptop-eapd"
in
/etc/modprobe.d/alsa.conf
with a model from
/usr/src/linux/Documentation/sound/alsa/HD-Audio-Models.txt
I am not really sure about this, because the chipset `Realtek ALC892` is not included in that file.
Which information helps you when debugging this? The Laptop is a Schenker `XMG P711`, it is build upon some barebone, possibly Clevo, but I'm not even sure.
Thanks for any advice.

I had this problem, a few days ago. My bizarre fix was:
Boot into the latest Ubuntu LiveCD, notice that the microphone magically works, run alsactl store, then take a copy of /var/lib/alsa/asound.state
Boot back into your preferred distro, copy Ubuntu's asound.state across, run alsactl restore, then check the mic again, with: arecord -vv -d 4 /tmp/test-mic.wav && aplay /tmp/test-mic.wav
alsactl --help mentions /usr/share/alsa/init/00main which looks like a udev file, so maybe it's related to udev? |

| Well, unfortunately I have the same issue with ubuntu. I thought about giving ubuntu a try when I got the new laptop, but I quickly went back to Gentoo. |
