USB Audio on FreeBSD 5.2.1-release?

[Torfinn Ingolfsen]

Hei,

Are USB audio devices suposed to work without problems under FreeBSD
5.2.1-release?

I have a USB Speaker set, when connected to the machine, it is identifed
as:
# usbdevs -v
Controller /dev/usb0:
addr 1: full speed, self powered, config 1, OHCI root hub(0x0000),
            SiS(0x0000), rev 1.00
 port 2 addr 3:full speed, power 500 mA, config 1, USB Audio(0x0001),
                     C-Media INC.(0x0d8c), rev 0.10

It attaches as (from /var/log/messages):
Sep 24 17:02:31 kg-work kernel: uaudio0: audio rev 1.00
Sep 24 17:02:31 kg-work kernel: pcm1: <USB Audio> on uaudio0

However, when i try to play a MP3 file (using XMMS) it sounds stuttering
or "choppy" if you know what I mean.
The same MP3 file sounds fine when played on the internal sound device.

I have googled, but couldn't find anything on hw to fix this.
BTW, does anybody know how to configure Zinf to use another device than
the internal one?

Any hints appreciated.
