I game on Audiophile today on Gnu Librem 5 device. The test was to bypass Pulseaudio, and i got a very nice High Rest output. I still working for more pure sound output on Gnu Librem 5.
The benefits to bypass Pulseaudio is to direct delivery the audio signal to the sound card without alteration, manipulation, resulting in a bit-perfect output and power save via low cpu. This also eliminate potential artifacts or distortions introduced by resampling or bridges, improvement the purity on the sound from direct dac/amp horsepower hardware output.
DO NOT use L5-earbuds for HR test.
On my test i see that wav has better sound than flac, still need testing aiff.
