I did a clean i386 FC2 T2 install with SELinux disabled and later installed xmms-mp3 from Livna. I was pleasantly surprised that MP3s played immediately without fiddling with alsamixer and the volume control applet worked fine. However, upon reboot, no volume and after starting alsamixer, it shows PCM as muted with zero volume although the Master was not muted and volume level was per the volume control applet. This is with the NForce2/Realtek ALC650 Rev 2 all properly installed during installation and with all initial modprobe.conf settings unmodified. I am not using surround sound but I note that in alsamixer, Center came up at 100% but thankfully muted. This is fixed in 7.49-1. |
By default, ALSA drivers are "mute" after being loaded. If user starts a mixer (e.g. alsamixer) to un-mute the audio channels and set the mixers, these settings will not survive the next reboot and the system's audio starts "mute" again. Initscript "halt" contains the following lines for old OSS/Free audio drivers, which save mixer settings on reboot/shutdown: # Save mixer settings, here for lack of a better place. grep -q "\(sparcaudio\|sound\)" /proc/devices if [ $? = 0 -a -x /bin/aumix-minimal ]; then runcmd $"Saving mixer settings" /bin/aumix-minimal -f /etc/.aumixrc -S fi With ALSA, it should be similar, but done with "/usr/sbin/alsactl store" (or amixer), which saves settings to /etc/asound.state. These would be restored (via modprobe.conf) when the kernel modules are loaded. Note that the following entry in /etc/modprobe.conf is not enough, because reboot/shutdown does not unload kernel modules: remove snd-ens1371 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-ens1371 Version-Release number of selected component (if applicable): initscripts-7.48-1 How reproducible: Always Steps to Reproduce: 1. run alsamixer and change mixer settings 2. reboot 3. run alsamixer to verify mixer settings Actual Results: Mixer settings haven't survived the reboot. Expected Results: Mixer settings should have survived the reboot. Additional info: Is "aumix" package still of use anywhere?
