[Bug 267913] Re: hda-intel: IRQ timing workaround is activated for card #0. Suggest a bigger bdl_pos_adj

[Derek Simkowiak]

Comment #46 worked for me too.  Thanks Locque.

This problem appeared out of nowhere on my laptop.  I recently installed
Webcamstudio and xawtv.  I also recently plugged in a couple of
different USB webcams: Logitech and Kensinton.

Perhaps the USB webcams triggered a problem, because I was using my
third USB jack and "usb3" shares an IRQ with HDA Intel, my sound chip:

dereks at dereks-laptop:~$ cat /proc/interrupts | grep Intel
 21:      72781          0   IO-APIC-fasteoi   uhci_hcd:usb3, HDA Intel


Maybe one of the udev scripts triggered a change for the default sound?
