Bug 295933 - uaudio(4): idle capture stream clobbers active playback sample rate on devices with a shared UAC2 Clock Source - device unusable

Dear FreeBSD multimedia development team, I'd like to submit to your
attention the following bug:

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=295933

affecting the usb audio chain with a specific USB DAC, the renowned Okto
Research DAC 8 stereo, but potentially involving similar devices with the
same chip implementation.

I could make the device work just "hiding" the capture stream, yet
the issue would require an appropriate, expert-led intervention.

While investigating this issue, I learned of the passing of the
much-respected and highly regarded contributor Hans Petter Selasky.
I would therefore like to ask whether there is currently a designated
maintainer for the USB audio stack and what the prospects are for
maintaining and developing the USB audio subsystem (and virtual_oss) both
now and in the future.

With kindest regards.
