Pulse certainly does its own audio processings.Apps can do their own audio processing, although it's uncommon.This is how sound works on Linux:Īpp > Pulse Audio > ALSA > actual soundcard In order for changes to take effect pulseaudio needs to be restarted with pulseaudio -k in a terminal, or by log out and log back in.Ībove answer is correct, but it will change Pulse Audio settings only. Save this file as ~/.pulse/nf or in it's original location (you need to be root then). Possible entries for the sample frequency are anything between 00 Hz (choose sensible values!)
Possible entries for the sample format are: u8, s16le, s16be, s24le, s24be, s24-32le, s24-32be, s32le, s32be float32le, float32be, ulaw, alaw
Always keep in mind that this may be on cost of system performance or stability when choosing extreme values. Uncoment them and replace them with values that suit you better. This means they are not read as the entries given here are the defaults. Look for the following entries: default-sample-format = s16leīoth are commented out with. Please backup the original settings to restore the defaults in case som settings break your audio. To change the sample rate and audio bit depth we need to edit the configuration file for the pulseaudio server /etc/pulse/nf
