[ALSA] Firefox vs Chromium: Which crap sounds better?

Firefox downsamples Hi-Res Audio to 44.1 kHz, or it prefers to play 44.1 kHz audio format, because of PreferredSampleRate

about:support 

Media
-----

Audio Backend: alsa
Max Channels: 10000
Preferred Sample Rate: 44100

Chromium downsamples Hi-Res Audio to 48 kHz (or it prefers 48 kHz).

To find out which crap sounds better, you may try to conduct a blind test, a scientific method where listeners evaluate options without knowing their identity or brand.

$ firefox 2>&1 youtu.be/dMTKSSqDwyU
Input:  44100 Hz, 2 ch, 's32_le' (0xa): dummy = 0, period = 1764
Output: 48000 Hz, 2 ch, 's16_le' (0x2): dummy = 0, period = 1920
Rates:  44100 --> 48000 (J: 0.00%, T: FFT, W: Vorbis)
Ok.

To disable resampling, or change PreferredSampleRate, one may try to recompile Firefox.
There is a manual for Ubuntu newbies.
