[orca-list] Help with Ubuntu 10.04 and sound card recognition

[Edu Camargo <edumusico gmail com>]

Guys,

It's been a long time far from the list. In fact i was not very active, 
since I had some struggles on my side, but things are getting back into 
place.

I'm planning to install Ubuntu 10.04 on my desktop, but I'm having a 
dificulty on getting sound to work through Live CD.

My machine is an Athlon X2 4000, 2.11Ghz, 2gb of RAM, the mother board 
is an Asus m2n-SLI with built-in sound card, and I also have an Delta 
Audiophile 2496 connected on my computer.

I've tested the AMD64bits version, and after some investigation I got 
stuck into the following:
Booted through Live CD with the accessibility with screen reader 
enabled, Ubuntu loaded propperly, except sound. Checked the sound 
control with sighted assistance, the levels are shown as if it was 
possible to hear something. Then I've tried the alsamixer utility and, 
to my surprise, The only card recognized by the alsamixer was the 
Audiophile 2496, which for some reason I was not expecting it to be this 
way. The built-in sound card is enabled via the BIOS.

A lot of sites suggest that M-Audio Delta Audiophile 2496 and Ubuntu 
don't work well with Alsa and Pulseaudio, and I've read that OSS is the 
best alternative for users of this particular card. I'm also planning to 
test Ardour which seems to be GTK-based, but of course I'd use the 
desktop as my working environment.

I was happy that at least, My Delta was recognized, but I need a clue on 
how to make things work before installing the system. I wouldn't love to 
lose the freedom of installing and setting up my computer with Ubuntu 
the way we are capable of doing today, with the Orca's assistance.

Any advice on this subject will be very, very appreciated.

Thanks in advance for your support.

Sincerely,

Edu Camargo.
