After upgrading to kernel 2.6.20-1.2933.fc6 and alsa-lib version 1.0.14 release 0.1.rc1.fc6 soundcard stopped to work ( before was ok!) Soundcard is (lspci -v): 00:14.0 Bridge: nVidia Corporation MCP51 Ethernet Controller (rev a1) Subsystem: Holco Enterprise Co, Ltd/Shuttle Computer Unknown device 5530 Flags: bus master, 66MHz, fast devsel, latency 0, IRQ 20 Memory at fe02b000 (32-bit, non-prefetchable) [size=4K] I/O ports at d400 [size=8] Capabilities: [44] Power Management version 2 If I type: [root@shadow /]# alsamixer I get: ALSA lib control.c:910:(snd_ctl_open_noupdate) Invalid CTL default alsamixer: function snd_ctl_open failed for default: No such file or directory
please attach /root/scsconfig.log (can be created by system-config-soundcard)

What card do you use? Conexant CX23880/1/2/3 PCI or nVidia Corporation MCP51 AC97 Audio Controller (this one may be integrated). You can try to remove these lines from /etc/modprobe.conf: alias snd-card-0 snd-intel8x0 options snd-card-0 index=0 options snd-intel8x0 index=0 and reboot your box.
My card is an integrated one from nVidia Corp (MCP51). I tried to remove the lines from /etc/modprob.conf, and not it looks like: alias eth0 forcedeth alias scsi_hostadapter sata_nv alias dvb cx88-dvb I also restarted my box, but it didn't work! :(
For your info, this is the description of my audio hardware (lspci -v) 00:10.2 Multimedia audio controller: nVidia Corporation MCP51 AC97 Audio Controller (rev a2) Subsystem: Holco Enterprise Co, Ltd/Shuttle Computer Unknown device c5d6 Flags: bus master, 66MHz, fast devsel, latency 0, IRQ 23 I/O ports at dc00 [size=256] I/O ports at d800 [size=256] Memory at fe02c000 (32-bit, non-prefetchable) [size=4K] Capabilities: [44] Power Management version 2
Additional and hopefully info: last night I downgraded my system to alsa-lib 1.0.13 and it restarted to work... Actually it is the only package not up to date in my fedora system.. so I can confirm the problem is strictly connected to alsa-lib 1.0.14 upgrading...
Aha. Please check if the update to 1.0.14 breaks your box. Please run system-config-soundcard and generate the /root/scsconfig.log (in the "System" tab) for 1.0.13 and 1.0.14 and attach it here. It could me help to find out where the problem is. Thanks!
