>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:
