Sorry for cross-posting. This bug looks like it affects the following packages:
* ALSA (0.9.8) * OSS audio drivers (kernel 2.4) * gnome-media From a user's point of view, difficult to tell which one is the culprit, thus difficult to take a guess at which package should receive the 'reportbug', so... ***** On my iMac CRT, I compiled alsa-source with only snd-powermac. The module gets loaded by alsa-utils, except there is no sound and the alsamixer refuses to work; the sliders won't move, except for the Beep one. Also, the controls proposed in Gnome2 mixer simply don't match what this iMac has. Unless I'm mistaken it has: 1) external output (stereo out) 2) built-in speakers (stereo out) 3) external input (stereo in) 4) built-in microphone (mono in) 5) CD audio input (stereo in) 6) ...possibly more, e.g. separate volumes for the two headphones? ***** What Gnome2 mixer gives me instead (on OSS, using dmasound_pmac - it works, but hickups on e.g. sustained hard-disk accesses): 1) main output (stereo out) 2) built-in speakers (stereo out) 3) external input (stereo in) 4) built-in microphone (mono in) 5) CD audio input (stereo in) 6) PCM ***doesn't seem to affect anything*** ...however, even though the speakers and master volumes successfully manage to control tehir functions independantly, in practice, nothing seems to manage to correctly save the settings independantly; when I reboot, both have the value last saved for the Main volume. Also, the master volume actually kills the output if I bring the slider to the maximum value. Besides, I always get the following in syslog, when moving the sliders: Nov 16 15:58:52 localhost modprobe: modprobe: Can't locate module sound-slot-1 Nov 16 15:58:52 localhost modprobe: modprobe: Can't locate module sound-service-1-0 Nov 16 15:58:52 localhost modprobe: modprobe: Can't locate module sound-slot-1 Nov 16 15:58:52 localhost modprobe: modprobe: Can't locate module sound-service-1-0 Nov 16 16:03:17 localhost modprobe: modprobe: Can't locate module char-major-10-134 ***** What Gnome2 mixer gives me instead (on ALSA, using snd-powermac - doesn't work): 1) main output (stereo out) 2) built-in speakers (MONO out) 3) external input (stereo in) 4) built-in microphone (STEREO in) 5) CD audio input (stereo in) As you can see, incorrect features are provided for the outputs AND microphone. Besides, I always get the following in syslog, when moving the sliders: Nov 16 16:10:40 localhost modprobe: modprobe: Can't locate module sound-slot-1 Nov 16 16:10:40 localhost modprobe: modprobe: Can't locate module sound-service-1-0 Nov 16 16:10:40 localhost modprobe: modprobe: Can't locate module sound-slot-1 Nov 16 16:10:40 localhost modprobe: modprobe: Can't locate module sound-service-1-0 Nov 16 16:13:52 localhost modprobe: modprobe: Can't locate module char-major-10-134 What is common in both ALSA and OSS syslog lines on Gnome2 is an off-by-one error. ***** I tried running 'alsamixer' from commandline and get the following controls (looks a LOT closer to the hardware I have, although the Mic should be mono): Master Headphon Headphon Line CD Mic PCSpeak AutoMut Beep All sliders refuse to be moved, except the one controlling "Beep". ***** What I have in my /etc/alsa/modutils/0.9: ### DEBCONF MAGIC # This file was automatically generated by alsa-base's debconf stuff alias char-major-116 snd alias char-major-14 soundcore options snd major=116 cards_limit=4 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss alias /dev/dsp* snd-pcm-oss alias snd-card-0 snd-powermac alias snd-slot-0 snd-card-0 alias sound-slot-0 snd-slot-0 ***** Can anyone shed any light on this?
