I only try to get sound via the optical output to my amplifier. Steps to Reproduce: 1. system-config-soundcard 2. Normal setup: select iec958, software mixing not disabled 3. Play: no sound, press yes to the question anyway, close 4. aplay /usr/share/system-config-soundcard/sound-sample.wav -> no sound 5. system-config-soundcard 6. iec958, disabled software mixing 7. Play: no sound, press yes to the question anyway, close 8. aplay /usr/share/system-config-soundcard/sound-sample.wav -> SOUND!
Created attachment 131836 [details] scsound.log from the last system-config-soundcard run
It should be fixed in FC6, please reopen if not.
So what is the problem? How can I get a fix to FC5? Does something like getting a new alsa-lib or kernel help? Or is there a patch somewhere?
A patch and/or package for FC5 isn't available, it should be fixed in FC6test2.
So can you at least give some information about the problem so that I can try to get it working without installing FC6test2? Maybe a bug report in alsa side?
If you want to use s-c-s for configuring your card, you have to use alsa-lib/alsa-utils/system-config-soundcard packages from devel (rawhide). (The best way is download them as src.rpm and rebuild them with rpmbuild --rebuild package.src.rpm) And you definitely should have alsa-lib-1.0.12rc1 or later. This bug is a problem with alsa-lib (with configuration files located in /etc/alsa)
Thanks. After rebuilding alsa-lib, alsa-utils, cairo, pycairo and system-config-soundcard from development it at least is able to configure it and play the sample. But I have to say that the sound is not correct: * Playing several oggs at a time does not work like it should. Instead of getting properly mixed sound, the first sound somehow changes. * It plays the oggs too fast. ogg123 says that it is 44100 Hz, my amplifier says it is 44.1 kHz, but it plays it too fast. I can workaround this by using the alsa rate plugin to convert it to 48000 Hz.
Could you check it in aplay? It may be a problem in ogg123.
Also aplay plays too fast. My kernel currently is 2.6.17-1.2157_FC5smp.
