It's an odd situation. I guess you didn't install the driver properly. Otherwise you must have /dev/snd/control*, PCM, else. How to install the alsa-driver externally depends on the distro. I'd advise you to ask on a distro forum about it at first. The rest debugging starts after you can install the sound drivers properly. thanks, Takashi > friendly greetings > Ludwig > > 2009/6/30 Takashi Iwai <tiwai@xxxxxxx> > > At Mon, 29 Jun 2009 20:06:47 +0200, > Ludwig Maes wrote: > > > > Tried the snapshot, > > still the same, alsa-info.txt attached > > Hm, just through a quick look at the output, there is no obvious > problem.
