[vlc] Audio filters: bug?

[Forest Bond]

Hi,

I'm dealing with a lot of audio-related problems.  They manifest as either a lot
of audio output starving issues or upsampling due to apparent clock drift,
depending on the specifics of the configuration.

I thought I was dealing with an ALSA bug, but I notice this:

[00000349] main private debug: using audio filter module "float32tos16"

--------------------------------------------------------------------------------

What's with the 52800 Hz?  It looks like we're doing:

mpga 48000 Hz Stereo -> fl32 48000 Hz
fl32 52800 Hz -> fl32 44100 Hz

Should that be this?:

mpga 48000 Hz Stereo -> fl32 48000 Hz
fl32 48000 Hz -> fl32 44100 Hz

What am I missing here?  If this is a bug, it would explain a lot about why I
can't get ALSA to fix things :)  That signal chain would be impossible to keep
sane.

Thanks,
Forest
