usb audio in current

[Marco Wertejuk]

Hi,

I'm using a Audiotrak Maya 5.1 USB Audio Controller with an
IBM Thinkpad A22m, it gets identified in dmesg like this:
uaudio_add_selector: NOT IMPLEMENTED
uaudio0: audio rev 1.00
pcm1: <USB Audio> on uaudio0
uhid0: vendor 0x0c45 USB Audio, rev 1.10/1.00, addr 2, iclass 3/0

cat /dev/sndstat shows this (pcm0 is my onboard soundcard):
FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: <CS461x PCM Audio> at irq 11 (1p/1r/0v channels duplex default)
pcm1: <USB Audio> at addr ? (1p/0r/0v channels)

The USB Audiocontroller uses a samplerate of 48kHz by default,
and therefore playback is distorted and slightly pitched up,
because the 44.1kHz audio data is played at 48kHz.

When setting the samplerate for mpg123 audio playback to 48kHz
it sounds correctly, but I can hear a loss of quality, maybe the
mpg123 resampling algorithm isn't very good, because resampling
with sox sounds much better.

Are there any plans to improve USB Audio support, for example
setting the samplerate if possible, adding record support, or
just merge to a newer version from the NetBSD driver?
