Update of /cvsroot/xine/xine-lib/src/audio_out
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv15684/xine-lib/src/audio_out

Modified Files:
	audio_alsa_out.c 
Log Message:
Summary: For alsa-lib version 1.0.9 or above, we can detect if the hardware can do resampling or not.

If resampling is not supported in hardware, old alsa normally does software resampling, but the current alsa-lib software resampling is not very good quality, so as we can detect if the software resampler is being used, we can choose to use our own high quality resampler.
TODO: This requires the addition of a new ./configure detection option HAS_ALSA_1_0_9
