ALSA ,OXYGEN, HT Omega sound card not recognized by driver

Hello,

I'm trying to configure my HT Omega sound card which uses the oxygen sound module to work with alsa. After loading the required modules, I run alsaconf, the sound card is detected, however, lspci still shows it as an unknown device. Also, when I run alsamixer, I get an error message. Any Ideas?

tux ~ # alsamixer
alsamixer: function snd_ctl_open failed for default: No such device

0. lspci uses it's own database, update-pciids command will pull in the freshest one, so this "unknown" really means nothing;
1. What version of ALSA you are using, it's always worth to try the latest, or even development version.

I ran update-pciids and now I get:

tux ~ # lspci | grep -i audio
00:08.0 Multimedia audio controller: C-Media Electronics Inc CMI8788 [Oxygen HD Audio]

But I still get this error:
tux ~ # alsamixer
alsamixer: function snd_ctl_open failed for default: No such device

Also, I'm using the latest alsa 1.16 and followed these instructions.

Code:

This is the list of devices on my rig, I do not use OSS emulation.
Did you try using in-kernel driver?

richcm · 05-08-2008, 04:41 PM

I did some time ago, but I couldn't find the driver. How did you set up yours?

tux linux # uname -r
2.6.24-gentoo-r4

Emerson · 05-08-2008, 05:27 PM

2.6.25-r2 has it. I'm sorry misleading you. I do not have this card, my example was intended to show there has to be a control device.
