The previous commit was misleading due to the flag names used.

The rationale for this change is that it is ok to return EAGAIN on first
read as playback has not started.  Then it shoud wait on every subsequent read.

This is what makes the high precsision throttling of pad(4), for which these
degree of fine-grained sleeps are not possible in userland.  This is a

Convert double block size of data though the play back filters.  This is
primarily for when audio mixing is disabled to stop inserting silence when

This change should have no effect when mixing is enabled as there is only

Speed up improvements for MIX_FUNC.

As suggested by jmcneill@.

(nat)

Use correct combination of mix ring block size and vc playring used low
for signalling the writer or fetching data from the vc play ring filters.

When dealing with the ring buffer sc_mpr.s it is necessary to use the hwvc
or mixring block sizes as they represent the final size of the data to be
played back from the stream vc.

When dealing with sc_pustream when there is play back filters or not one
should use the vc->sc_mpr.blocksize, as this represents the amount of data
before going through play back filters.

This should address PR kern/52685.

(nat)

Add vc to debug messages in audio_mix.
Also add debug message when available data in the vc is less than the mix

(nat)

For the virtual stream it is required to insert silence.  As these streams
are not harware streams audio_pint_silence is ineffective.

As audio_mix() was the only consumer of audio_pint_silence it has been
removed along with sc_sil_count - which was only used by this function.

(nat)

The harware vc is rounded to a power of two then round_blocksize is called.

This improves playback and makes it possibile to use mmapped audio on usb.

(nat)

Improved audiostartp for when audio mixing is disabled.

One block of silence is also played in audio drivers using start_output
when draining the hardware, this helps playback of short (less than
blocksize) samples.

(nat)

Plug memory leak as the mixer state does not grow or shrink when audio
mixing is disabled.  This avoids triggering a panic also.

(nat)

Don't return EIO falsely when dealing with the hardware vc.
Draining of the hardware vc on close is now possible.

There currently is a problem draining the last block with the mixer

AFAIK there will be a problem wiht vs(4) on x68k with the mixer disabled

(nat)

Revert commit rev 1.419 to audio.c.  This should address PR kern/52685.

This also means that drivers that have a static block size will have more
latency at lower sample rates/precision/channels.  Also audio drivers that
do more than supply rounded blocksizes in their round_blocksize functions
will have to be changed.

(nat)

round_blocksize is only used for the hardware ring buffer.  All other
buffers (mix ring, streams) are set to be a power of 2.
