PulseAudio

  • configure sampling rate:
# edit /etc/pulse/daemon.conf

## default-sample-format = s24le
default-sample-format = float32le

## default-sample-rate = 96000
default-sample-rate = 48000
## alternate-sample-rate = 44100

## resample-method = soxr-vhq
## resample-method = speex-float-3
resample-method = speex-float-5


# then restart pa

  • speex-float-5 is for 96KHz, speex-float-3 is ok for 48KHz

  • debug current pulseaudio stream:

pacmd list-sink-inputs
  • for youtube music (chrome), sample spec is: float32le 2ch 48000Hz, no resample occurred
  • fro steam game, sample spec same as above, but it still do resample
  • for Rhythmbox, sample spec for normal CD: s16le 2ch 44100Hz, which will apply resample to 48000Hz with speex-float-5
    • hi-res CD: s24le 2ch 96000Hz playback will be down sample, although DAC support higher.
  • if you want to hi-res, set default-sample-rate = 96000, but this will cause steam/chrome always up-sample

GPU

  • video hardware decode in Chrome with nvidia
/usr/bin/google-chrome-stable --ignore-gpu-blocklist --disable-features=UseChromeOSDirectVideoDecoder --use-gl=desktop --enable-features=VaapiVideoDecoder %U
