Post subject:  emu10k1 (SB Live) not recognized by ALSA in LiveCD

Hello.

I'm attempting to run a MythTV frontend from the LiveCD (ie: NOT installed on a HD), and have everything working except the sound.

The card is detected during the bootup:
Code:
Soundcard : Creative Labs SB Live! EMU10k1 driver=emu10k1


'lspci' shows:
Code:
01:08.1 Input device controller: Creative Labs SB Live! EMU10k1 (rev 05)


and the file /etc/modprobe.d/sound contains:
Code:
alias snd-card-0 snd-emu10k1
options snd-emu10k1 index=0



However, from there, it appears as though the card actually does not load. Running 'alsamixer' gives the error:
Code:
alsamixer: function snd_Ctl_open failed for default: No such device


and 'lsmod | grep snd' gives no results.

So I tried 'modprobe snd-emu10k1', but I get the error:
Code:
Setting up ALSA...^GInvalid card number.
Usage: amixer <options> [command]
Available options:
 ... etc, typical help screen


This repeats a LOT of times. If I use the command 'modprobe snd-emu10k1 index=0', I get the exact same result.

After running either of the modprobe commands, the lsmod command shows that the modules are now installed:

soundcore              11360  1 snd



However, after this, alsamixer still gives the same error. A quick check of /dev shows that there are no sound-related devices (dsp, mixer, etc...)

Any thoughts? Sound is the only thing holding me back... :cry:

Thanks

Yeah Ive got the same problem.. same sound card 2..
Im trying to use the cd as a remote frontend every thing works except sound..

I found I had to run:

#/usr/share/alsa-base/snddevices
#alsaconf

now alsamixer works fine and I can play sound using

aplay /usr/share/sounds/testing.wav

but I cant get the sound out of the frontend.. tried the general settings in mythfrontend to use /dev/dsp and /dev/dsp0 (symlink anyhow) but still no sound..
