There is still an issue with MSI interrupts for HD Audio devices on
AMD systems, in the past we've been able to workaround it in the driver.
You can certainly try that. But from previous testing by other users
this trick no longer works for newer AMD chipsets.

http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/sys/dev/pci/azalia.c.diff?r1=1.246=1.245

Your device would be "PCI_PRODUCT_AMD_17_3X_HDA".

It shouldn't be related to -current.  Can you check out this email:

audio stops frequently with current

[Gregory Edigarov]

Hello,

symptoms like this:
chromium plays video with audio (youtube)
mostly after pause, it loses audio.
while this happen it could show spinner,
but sometimes it can play video no problem, but no audio.
