I have 2 soundcard - a M/B built in Intel AC97 and an old Aureal (later SoundBlaster). This is because there’s a problem with Intel’s microphone in XP. So I use Intel for playback and Aureal for recording.
Now, how do I duplicate same setup in Suse (to avoid switching plugs) ? I am a bit lost in where to specify hardware to be used for recording and playback.
This problem with the microphone with the Intel AC97, has it always been like that or did the mic circuitry fail at some point? If it has always been so, do you by any chance need to turn on the +20dB boost control? Many computer sound devices have a single mic input that handles both low and high output mics using a boost switch for the low output mics.
The problem is with “Connector sensing” feature of AC97 - i.e. it would lose mic every now and then. In Windows, the easiest thing was to just use 2nd card, since there I can easily specify different hardware sources for playback and recording. I don’t recall why I couldn’t just switch everything to Aureal, there was a reason though.
Coming to think of it, I now recall that during my short encounter with Ubuntu 9.10 the mic did work, so the problem is likely not with my setup but with Aureal drivers in SUSE.
