--- Comment #227 from Alexey Loukianov mooroon2@mail.ru 2011-11-10 18:37:11 CST --- P.S. Sorry for hi-jacking the bug report a bit more but I have a semi-related question for Andrew to ask: looks like that the default samplerate for dsound is set to be 44100Hz, which differs from the typical 48000Hz value that's being used by most AC97 codecs. HDA codecs typically use 96000Hz or 192000Hz as their base internal samplerate (ones that don't use PDM internally, but latter are extremely rare and are typical only for Hi-End sound interfaces). It leads us to a fact that if we've got DSound resampling everything that's being fed into it to the 44100Hz, then it would get another resampling to 48KHz (96/192), either in software (dmix/pulse/name your beloved soundserver here) or in hardware (SB Live! cards resample internally to 48KHz using built-in DSP for such cases). Maybe it would be wise to change the default to be 48KHz? It would save users from extra resampling in good cases and wouldn't hurt quality much for unfortunate case having non-matching hardware internal sample rate.
