So, what do I have to do to > forward the sound to my usb device? Probably windows is disabling any existing sound card or at least making the USB the "default" sound device. Unfortunately there is no equivalent with alsa currently. So assuming that you've got the alsa drivers loaded for this device (/proc/asound/cards should contain two entries), you can usually specify alsa device as "hw1,0". The exact method for doing this depends on what app you are using. For example on amarok with the xine it is under Configure Amarok... -> Engine -> ALSA Device Configuration. If you enter hw1,0 for Stereo there, then 2 channel audio should be played on the first pcm of the second sound card. You should also be able to do this with a .asoundrc file, with an entry like: pcm.default { type hw card 1 device 1 } The above is really primitive, without any dmix plugin (software mixing), so only one app could use the device at a time unless it does hardware mixing. Mostly this is just to give you an idea of where to look! ;-) -Richard -- gentoo-user@gentoo.org mailing list
