I recently upgraded to 2.4.6 kernel and alsa 0.9xxxbeta; I had previously been using 2.4.2 and (I think) alsa 0.5.
Sound is now disabled at startup, though I can turn it back on by starting up the mixer (gnome desktop, woody system). There are several other anomolies: 1) Logs show errors Jul 24 16:09:44 wheat modprobe: modprobe: Can't locate module sound-slot-1 Jul 24 16:09:44 wheat modprobe: modprobe: Can't locate module sound-service-1-0 modules.conf does not refer to either (uses sound-slot-0 and sound-service-0-1). 2) When I run alsaconf I get this error: Loading driver: Starting ALSA sound driver (version 0.9.0beta4): sbawe. alsactl not found, mixer settings will not be restored. Setting the PCM volume to 100% and the Master output volume to 50% amixer: Mixer 0/0 open error: No such file or directory Could not initialize the mixer, the card was probably not detected correctly. 3) When I run alsactl wheat:/usr/local/rootlog# alsactl store alsactl: SND CTL open error: Sound protocol is not compatible 4) Some error message about alsactl or alsaconf scrolls by when I start the system. Can anyone suggest what is happening, or how to fix it? By the way, alsaconf is still at v 0.5 (sid as well as woody), even though the drivers are at 0.9x.
