Mixer not resampling very well
|Reported by:||Pete||Owned by:||nobody|
If audio is generated at a different rate from the driver's sample rate, the output has crackles, hash and other artefacts. This seems to happen whatever the mismatched rates are. I originally noticed it with 96000 output and 48000 source, but, as I have now reduced my system's rate to 48000, I'm attaching two sample audio sweeps that are identical except that one was generated at 48000 and the other at 44100. If the output rate is not one of those, both will sound bad, but if you select one or the other of those rates in Media Prefs, the corresponding file will be a perfect sweep, and the other will have crackles and "ghost sweeps" in the background!
(My audio is HDA, but I assume that this is irrelevant because the resampling is done in the mixer.)
