Last modified: 2008-01-04 08:54:36 EST
Description of problem: With kernel 2.6.23.8-34.fc7 I no longer get sound from my SB Audigy2 Version-Release number of selected component (if applicable): kernel-2.6.23.8-34.fc7 How reproducible: always Steps to Reproduce: 1. Boot kernel 2.6.23.8-34.fc7 2. Try out any sound app 3. Actual results: No sound at all. Expected results: Sound from my speakers. Additional info: With kernel 2.6.23.1-21.fc7 sound is still there. The speakers are connected through SP/DIF out on the breakout module. Relevant lspci output: 05:01.0 Multimedia audio controller: Creative Labs SB Audigy (rev 04) 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: Installing spdif_bug patch: Audigy 2 EX [1005] this message is seen on both the working and non working kernel. Modifying mixer settings (Audigy Analog/Digital Output Jack and IEC958 Optical Raw) does not help.
OK with the latest kernel 2.6.23.12-52.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 2.6.23.1-21.fc7. Running alsactl restore gives:alsactl: set_control:991: warning: name mismatch (IEC958 Playback Default/IEC958 Playback Mask) for control #180 alsactl: set_control:993: warning: index mismatch (0/3) for control #180 alsactl: set_control:995: failed to obtain info for control #180 (Operation not permitted) 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.
