Re: [linux-audio-user] maudio quattro & jack

well, it's nice that this issue has been solved ... i was really annoyed by restarting alsa about a hundret times before i could perform ... but this is another problem ... using alsa's hw layer i get the following result: Sorry. The audio interface "hw:0" doesn't support any of the hardware sample formats that JACK's alsa-driver can use. using alsa's plug layer (asoundrc file from the alsa website) quattro1 / quattro2: Sorry. The audio interface "quattro1" doesn't support any of the hardware sample formats that JACK's alsa-driver can use. Sorry.
