2013-06-19 06:42:33 Nomad description On E-MU 0204 USB only 2-channel mode worked. In this mode the second pair of channels just duplicates the output of the first pair. Under windows E-MU control panel allow to switch to 2-channel or 4-channel mode. I ran USB sniffer, and it shows switch commands that the system send to the device: ====================================== Host send 2 bytes to device: Request: 0x1 Value: 0x400 Data: 01 01 //switching to 2-channel mode Data: 01 02 //switching to 4-channel mode ====================================== Looks like in Ubuntu the card by default stay in 2-channel mode. Switching to 4-channel mode apparently can be added to quirks.c DistroRelease: Ubuntu 12.10 Package: alsa-base 1.0.25+dfsg-0ubuntu4 Uname: Linux 3.9.6-030906-generic x86_64 Architecture: amd64 On E-MU 0204 USB only 2-channel mode worked.
