There may have been a misunderstanding about SNDCTL_DSP_SETBLKSIZE. It is only
useful to us if it can set an exact fragment size on Virtual OSS - otherwise it
does not provide any benefits over SNDCTL_DSP_SETFRAGMENT.

Did you test it? Because your current code won't run the SNDCTL_DSP_SETBLKSIZE
part AFAICT. It should produce 2 fragments of size 36864. Just replace the
SNDCTL_DSP_SETFRAGMENT ioctl with SNDCTL_DSP_SETBLKSIZE for testing.

But if it works now we can also opt to let it be and just use the
SNDCTL_DSP_SETFRAGMENT implementation we had before.
