[alsa-devel] No CD mixer on Intel G35 (Asus P5E-V(M))
Hello,
on my Asus P5E-V HDMI and my Asus P5E-VM HDMI (both Intel G35) alsamixer shows no CD mixer. Both boards have a CD audio connector and the CD-drive connected to it.

Same with 2.6.33.
On my P5Q-EM (Intel G45) the CD mixer appears in alsamixer.
I have no idea how to dig deeper in this, if you need more information, please just tell me.
Thanks for your work & regards Mario

I think the developers like to have the output of `alsa-info.sh` [1][2].
1. Did ALSA ever detected the CD mixer on this board? 2. Did you try all different model parameters [2]? If not and it does not work please also attach sanely named files with the output of `alsa-info.sh`. 3. Have you tried to build the modules yourself from Git head [1]?
Thanks,
Paul

Thanks very much for your hints. Output of `alsa-info.sh' is attached.

Hmmm, I found an asound.state in a very old backup (Jun 2009) which suggests it was once there. In the next backup (Aug 2009) it seems gone. I'm quite sure it was the same board like now (I had no other board with Intel HDA at this time). Unfortunately I cannot find out which kernel did run at this time. I tried old kernels from around this time but did not succeed. I also tried to downgrade the BIOS to the one around this time, no success either. Maybe somebody is able to deduce something more out of the asound.state files.

Aaaah, `modprobe snd-hda-intel model=asus-p5q' does the trick. CD mixer is there, playing a CD gives sound and the rest seems to still work too. This model gave some other new controls (Output: Channel Mode Switch: 6/8ch and Input: S/PDIF), I don't know how to test these. It did not remove any controls.
I assume it would be safe to autodetect `P5E-V HDMI' and `P5E-VM HDMI' to model=asus-p5q. There are two other models in the P5E-V* series: `P5E-VM DO', and `P5E-VM SE'. I don't really know them, but according to their manual they all seem to have the same Intel G35 chipset, the same Realtek ALC883 codec and a CD audio in connector.

Nope, I didn't :)
thanks again & regards Mario
