Description of problem:
With kernel 184.108.40.206-34.fc7 I no longer get sound from my SB Audigy2
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot kernel 220.127.116.11-34.fc7
2. Try out any sound app
No sound at all.
Sound from my speakers.
With kernel 18.104.22.168-21.fc7 sound is still there. The speakers are connected
through SP/DIF out on the breakout module.
Relevant lspci output:

05:01.1 Input device controller: Creative Labs SB Audigy Game Port (rev 04)
05:01.2 FireWire (IEEE 1394): Creative Labs SB Audigy FireWire Port (rev 04)
My card is a SB Audigy2 which needs:

Modifying mixer settings (Audigy Analog/Digital Output Jack and IEC958 Optical

OK with the latest kernel 22.214.171.124-52.fc7 (installed today) I still can't get
sound out of the SP/DIF. There is sound through the headphones. The latest
kernel which gives me sound is 126.96.36.199-21.fc7.

Maybe this has something to do with it.
comparing the source from the emu10k1 driver for both 1-21 and 12-52 showed
nothing changed so I look elsewhere. After deleting both /etc/alsa/alsa.conf and
/etc/alsa/asound.state I now have my sound back from the coaxial SP/DIF output
on the LiveDrive. So not a bug but strange nonetheless.
