CVS commit: src/sys/dev/pci/hdaudio

Module Name:    src
Committed By:   jmcneill
Date:           Mon Oct 24 02:08:23 UTC 2011

Modified Files:
        src/sys/dev/pci/hdaudio: hdafg.c

Log Message:
ossaudio's SNDCTL_DSP_GETOSPACE will call AUDIO_SETINFO if the block size
isn't a power of two, and since the block size is changing this tells
audio(4) to halt output, reconfigure the device, then trigger output again.

mplayer's oss driver uses SNDCTL_DSP_GETOSPACE a lot.

Instead of simply rounding to 128 bytes as required by the hardware, change
hdafg_round_blocksize to return one of 128, 256, 512, 1024, 2048, 4096,
or 8192.
