>Description:
audioplay expects to be able to pass the kernel audio stack raw 24-bit
PCM, but this doesn't work. the kernel only supports 8/16/32-bit PCM
PCM, so it fails with EINVAL.
>How-To-Repeat:
play a 24-bit wave file with audioplay
>Fix:
audioplay should pack the 24-bit samples into 32-bit samples,
as libao in pkgsrc does.
