This is likely to happen with a sound card that's constrained to a 
specific input format (i.e. 48KHz PCM) and an application is requesting 
a different format (i.e. 32KHz PCM).

To fix it, upgrade to ALSA 1.0.9 (which will enable automatic conversion 
for format-limited soundcards using analog output) or fix your .asoundrc 
( http://mythtv.info/moin.cgi/DigitalSoundHowTo ) to fix analog and 
digital output.
