If you're experiencing "buzz" like I think you are then it= 9;s the same
frame being queued
over and over again to the DAC. Typically I've only seen that happen he= re when I
have the kernel panic (we're not stopping audio DMA at this point, and<= br> I don't know
why it's looping over.)

<snip>

Even in the year of our lord "LLMs are available" there's onl= y so much
one can do
in long email threads; at some point bugs need reproducing, PRs need filing= and
developer / user time needs to happen. Let's be methodical about it to = help out
the sound folks in figuring it out.

Hello,

I usu= ally linten to youtube when doing poudriere builds. Music helps the process= and poudriere build better.

I use an usb dac with:
hw.snd.latency=3D10
hw.usb.uaudio.buffer_ms=3D8

IMHO= it helps a little.

Thanks,
