Bug ID: 230434
Summary: USB sound card fails to record
Product: Base System
Version: CURRENT
Hardware: arm64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: usb

I have a Griffin iMic USB audio sound card connected to a Raspberry Pi 3 B+ and
am running FreeBSD-CURRENT r335760.
After loading the snd_uaudio kernel module the device is correctly detected as
per the following dmesg log:
ugen0.7: <Griffin Technology, Inc iMic USB audio system> at usbus0
uaudio0 on uhub1
uaudio0: <Griffin Technology, Inc iMic USB audio system, class 0/0, rev

pcm0: <USB audio> on uaudio0
On trying to record from the device the user application concerned fails, and I
find in the dmesg output a series of the following errors:

I have tried different sampling rates with the same results. The Griffin iMic
works fine on FreeBSD 11.2 on Intel.
Any support would be appreciated.
Many thanks.
