NetBSD dstar.dstar.net 10.0_STABLE NetBSD 10.0_STABLE (GENERIC) #0: Wed Jun 12 09:11:06 PDT 2024  scole%dstar.dstar.net@localhost:/home/scole/nbsd/cvs/10_0/obj/sys/arch/amd64/compile/GENERIC amd64

>Description:
My system will lock up hard (can't ping machine, keyboard frozen) when viewing a video (e.g., youtube) in firefox and using usb audio.  I've tried using different usb devices (logitech headset, usb-to-audio-jack dongle) for the same result. It usually takes about 5 or 10 minutes but eventually the screen will freeze.

With usb audio, I can tell something is amiss because the video becomes laggy and unsynchronized with the audio, like the system is under heavy load.

When using the onboard Realtek audio (non-usb) device, things work fine.

If I just listen to an mp3 file with mplayer or mpg123 and usb audio, things works fine, so maybe there is there some kind of contention between the usb and video systems.
