Hello,

I've bought some USB speakers that I've having trouble getting to work.

Here is some relevant output. I hope someone can help me.

dmesg:

Hi truthe,

Create /etc/asound.conf:

pcm.!default {
        type hw
        card 1
}

ctl.!default {
        type hw
        card 1
}

Restart alsa:
/etc/init.d/alsa-utils restart

Launch mcop :)

Has anyone run more than one set of the S150's from a single dockstar? Given the price & power output of these speakers, running 4 may be more effective than stepping up to a more expensive model.
