Automatic Downsampling PulseAudio/ALSA

Postby kogami on Sun Jan 12, 2014 4:06 pm

Hello Everyone,

I'm currently running a Linux Mint 16 setup with ALSA and Pulseaudio configured. I've gone through every configuration file on both ALSA and PA that I can find, attempting to put the settings to 24/96 output in every instance. I don't know whether ALSA or PA is to blame, but higher resolution files are being automatically downmixed to 16/48, which is less than ideal. These are the files I've edited:


cat ~/.asoundrc:
defaults.pcm.!rate_converter "samplerate_best"
defaults.pcm.dmix.!rate 96000
defaults.pcm.dmix.!format S24_LE

I don't know guys. I'm out of ideas, does anyone else have any?

Linux Mint is funded by ads and donations.

Yes - that higher than 16 bit, 44.1K is a waste, sometimes with negative audio artifacts:
"OK, so 192kHz music files make no sense. Covered, done. What about 16 bit vs. 24 bit audio?" etc.
