Remove ALSA resampler bypass

2012-02-01T02:45:20+00:00

In 2005, xine-lib 1.1.1 added the following change:

xine-lib (1.1.1) 2005-11-15
  * Improve sound quality when using alsa 1.0.9 or above.
    When playing a 44.1khz stream on a 48khz only capable sound card.
    It bypasses alsa-lib resampler and uses xine's

That made sense when Alsa's resampling was the worst thing ever.  But now,
if one installs alsa-plugins-1.0.25 and puts this in ~/.asoundrc:

defaults.pcm.rate_converter "samplerate_best"

Alsa then does markedly better resampling (using libsamplerate) than
xine-lib (using its own algorithm).  The bypass added in 2005 is therefore
preventing the use of a higher-quality algorithm and blocking the ability to
tune that algorithm in ~/.asoundrc, and no longer seems to have any
redeeming value.
