Hi

Got three sound cards on my system.
Disabled the on-board sound interface in the BIOS.

USB card 0 is an RME Babyface, known to not work in GNU/Linux.
USB card 1 is the M-Audio Fast Track Pro that I'm trying to get working for just playback.

I've compiled ALSA into the kernel, should I be using modules?
I tried them as modules, didn't work since I got something else wrong too :?

Haven't any experience with ALSA, would be very grateful for any help :)

Thanks,
Mody

Yes. It's easier to unload and reload them without having to reboot.

What else went wrong?

What kind of audio work do you want to accomplish with this sound card?

Ah, that's a great point you make, def more manageable as a module. Thank you for that wisdom.

As for what else went wrong, honestly I really don't know actually since ALSA mixer doesn't report any playback device for either sound card. No sound basically. I just need it to playback audio. I could keep trying different things, though I posted here thinking I might save myself some time and learn something towards the right direction.

Thanks for reading... much appreciated. if you can help further and need more info do let me know.

Cheers :)

I might be able to help. If you're looking to produce music and audio of your own with your Gentoo box, you should check out the "Gentoo Studio" guide linked in my sig. Feel free to pick my brains. I don't have all the answers, but hopefully I can help with basic setup and get your M-audio working.
