--- Comment #1 from Hans Petter Selasky <hselasky@FreeBSD.org> ---
Hi,

Can you check what these two sysctls are set to:

dev.pcm.<N>.rec.vchanrate
dev.pcm.<N>.play.vchanrate

hw.usb.uaudio.buffer_ms: 8
hw.usb.uaudio.default_channels: 0
hw.usb.uaudio.default_bits: 32
hw.usb.uaudio.default_rate: 0

Also try to set:

hw.usb.uaudio.default_rate=3D48000

Maybe the high data-rate this interface supports overflows the USB budget.

--HPS
