Surround sound Snd-cmipci

Boffy · 01-15-2004, 02:06 PM

I would like to know what settings that i must use to get a 6 channel output from the cmedia 8738 sound card using the alsa driver on mandrake linux 9.2. I hope someone can help me as i really would like full sound so i can enjoy mythtv fully.

Cheers in advace

Read the driver docs for this chipset at the ALSA-Project web site, and in particular the instructions for using the asoundrc file.

I attempted to read and undersatand what that link was saying but to little avail. Does anyone have a card like my own working and if so could you please paste your configuration onto the post so i can give it a try.

Thanks for the help so far

I sort of solved the problem but i have a very faint output from the centre/bass. Here is my modules.conf file

alias sound-slot-0 snd-cmipci
above snd-cmipci snd-pcm-oss
options snd-cmipci snd_index=0 snd_id="C-Media-8738-6Ch"
options snd_pcm_hw_params_set_access(pcm, hw, SND_PCM_ACCESS_MMAP_INTERLEAVED);
options snd_pcm_hw_params_set_format(pcm, hw, SND_PCM_FORMAT_S16_LE);
options snd_pcm_hw_params_set_channels(pcm, hw, 6);
