I wonder what is normal Bit Depth for Audacious Player there are 16/24/32 bits available I tried them all seems fine.
I use stereo output for my speakers and I wonder what bit depth be the best for stereo output so not to overload the hardware or some, right now I set it to 24 bits.
You won't hear any difference when your music is still mastered with CD quality (PCM with 44,1 kHz samplerate and 16 bit audio bit depth) for mainstream consumption (loudness war).
Changing the PulseAudio defaults - which are set to CD quality - and setting higher values while still playing the same material from mainstream equipment will only result in computational overhead.
Questions on audio quality are often confused with questions on music taste or general preference.
Going beyond mainstream audio equipment and music formats (lossless CD rips are still mainstream) is rather off-topic for this site, but Monty Montgomery's lengthy article on Why 24-bit/192kHz music downloads make no sense is worth a read.
