Perhaps I am misunderstanding or maybe I have been unclear.
Pulse will not work on its own - it needs to have alsa installed, and alsa is installed when you install openSUSE.
Right, agreed. What I meant to say was we disabled/removed PulseAudio and went with 100% alsa. That failed miserably. Not only did the audio out not work, but the microphone which was working stopped.
However, to get pulse to work properly you need to install pavucontrol which controls whatever audio devices you have: audio card or chip, microphone, whatever.
But pavucontrol requires that you first set the audio device by installing alsamixer[#]. When you run alsamixer you need to begin by selecting the audio device with the F6 key (and then select/unmute/mute the appropriate channels). Once the correct audio device is selected pavucontrol will then be able to "see" it and configure it.
Did that. Pulled up alsamixer (cli version, I never use the gui version for this stuff). None of the audio channels were muted. All were maximized. This was quadruple checked and more. pavucontrol was zero help either... there, we could see that the microphone was apparently working - start an app that polled for mic input and we could see the signal meter bouncing... but no audio was being sent to test apps (eg Skype, Pidgin voice call etc). To make it more interesting, there was no confg for audio out. It was as if the system only found an audio in on this sound card, and that was all that was presented in pavucontrol and all that was presented in the KDE4 Multimedia > Phonon config as well... there we could set up the mic on a per-app-type basis, but for audio out the only option was PulseAudio Server (instead of the expected device name for audio out). So basically, this sound card, which I know DOES work in Linux (ie it was made to work in Ubuntu 10.10 by simply setting the alsa model option to "medion-md2") refused to work in openSUSE. I think I forgot to mention we attempted to set the model as well in both YaST and in the config file.
Just out of interest, has the correct audio device been selected in the BIOS?
From what I could dig up, this sound card (an onboard MCP79 HD card in a Medion All-in-one PC) seems to be the same card was is/was using in Apple Macbooks, and nowhere else (at least the only people posing as having issues either had a Medion or a MBP). I can dig up more
Yes, and if we boot to Windows 7 or Ubuntu 10.10, it works fine.. it only booting to openSUSE where it fails to work as expected. In the end a complete reinstall was done - after so much tinkering, things were royally messed up, and a reinstall was faster than undoing the mess. On reinstall the only way to acheive a complete system with working sound was to leave the default autodetected sound as-is where the microphone works, and plug in external Logitech USB speakers (which provide their own sound card)... then using this hybrid of internal sound card and external sound card things... "worked". It's a less than optimal config. details if anyone is interested... C. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
