>Description:
Every sound played on this VT8237A/VT8251 HDA controller with a realtek
Realtek ALC888 codec(?) is repeated about 70 times. When a sound is played
(e.g. by CenterICQ), the following messages are printed before the sequence
(with AZALIA_DEBUG defined):

azalia_open: flags=0x2
azalia_round_blocksize: resultant block size = 9600
azalia_round_blocksize: resultant block size = 9600
azalia_round_blocksize: resultant block size = 9600
azalia_round_blocksize: resultant block size = 8704
azalia_trigger_output: this=0xc1fe8000 start=0xcbc9f000 end=0xcbcade00 blk=8704 
{enc=6 2ch 16/16bit 44100Hz}
azalia_codec_connect_stream: fmt=0x4011 number=1
azalia_codec_connect_stream: leave with 0

and after the loop has finished:

azalia_halt_output
azalia_round_blocksize: resultant block size = 9600
azalia_round_blocksize: resultant block size = 8704
azalia_round_blocksize: resultant block size = 9600
azalia_round_blocksize: resultant block size = 8704
azalia_close

Relevant boot-time dmesg snippets:

 Disabling ioapic solves the sound looping problem:

 ---
 include "arch/i386/conf/GENERIC"

 no ioapic* at mainbus?
 ---

 Unfortunately, I need ioapic for MP support. Any suggestions how to
 debug this further and what information is useful?

State-Changed-When: Sun, 12 Jun 2016 01:15:39 +0000
State-Changed-Why:
Is this problem still current? I'm guessing probably not...

State-Changed-By: dholland@NetBSD.org
State-Changed-When: Sun, 26 Jun 2016 02:17:46 +0000
State-Changed-Why:
feedback mail bounced. given the various changes in ACPI and MP stuff, and
the transition from azalia(4) to hdaudio(4), assume that either the problem
is fixed or it's mutated past the point where keeping this PR open serves
any purpose.

If anyone runs into the same or similar problem, write in to this PR (or
file a new one...)
