usb audio

[ray]

i have an internal Yamaha AC-XG Sound Card on my laptop computer and i also have an external sound blaster usb card. i got sound working after i added device pcm to my kernel config.


FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: <USB Audio> at addr ? (1p/0r/0v channels)
pcm1: <Intel ICH3 (82801CA)> at io 0x1c00, 0x18c0 irq 9 bufsz 16384 (1p/1r/0v channels duplex)

that is from /dev/sndstat

~# dmesg | grep audio
uaudio_add_selector: NOT IMPLEMENTED
uaudio0: audio rev 1.00
pcm0: <USB Audio> on uaudio0
uaudio_add_selector: NOT IMPLEMENTED
uaudio0: audio rev 1.00
pcm0: <USB Audio> on uaudio0

the problem i am having is the audio is kind of choppy and lags. i was wondering if anyone knew a fix.
