Hi

for me following worked on a kubuntu 7.10 machine:

First execute 'asoundconf list' to get the correct name of the sounddevice, then do 'asoundconf set-default-card [name of sound device]'

I hope this works for you too,
bye

First of all: If you are using the ALSA backend or (with 1.5.4) the new PulseAudio backend, you have to make sure that the appropriate libraries are installed, namely libasound.so.2 and/or libpulse.so.0.

Then, if you are using older kernels than around 2.6.19 you will probably not be able to open a second sound channel if there is already some a sound daemon active (for instance artsd of KDE). In that case you have to setup properly to support mixing (search the web for 'ALSA dmix') or move to a more recent kernel (which already contains support for the dmix plugin.
