Sound difficulties with FC4

[ubunturefugee]

I'm having problems producing any sound from my SB Extigy. System Settings > Soundcard Detection finds both the onboard audio and the Extigy, but refuses to play any sound from the Extigy.

Any ideas?

The system uses as default card the first he "sees":
aplay -l
will tell you which card you have and their assigned number; if you check modprobe.conf, you will find a index number for each soundcard alias. My bet is that you onboard chip has index 0, and so come first.
You have to write a simple .asoundrc file (it's a hidden file, so the leading dot) in you home, setting the Extigy as default card and device.
The alsa-project wiki has a lot of instruction about the .asoundrc: search for your specific chip.

Try playing around with volume settings/preferences; mute and unmute. Also, play some wave files and music CDs. Mine just worked magically after that. :)

I'm still not quite sure what the problem is. Output of aplay -l

When I've got the Extigy selected as the primary audio device, I still get sound from the on-board. Do I need to edit the way they're slotted in modprobe.conf?

[daneel971]

I admit the output of aplay puzzles me: where is the Extigy? The modules seem to load.
The Extigy is the usb-device, right?
Test if it's working correctly with
mplayer -ao alsa:device=hw 1,0 file.mp3

No need to mess with modprobe.conf; do the modifications only via .asoundrc

I actually did get it working by changing how they were slotted in modprobe.conf. Just swapped the index numbers, works good enough. Volume knob on the front isn't working, slight clicking when changing tracks. Haven't tested the optical out or the remote control (which is supposed to be supported by the alsa driver).

Thanks a million for pointing me in the right direction.
