Pulseaudio settings for audiophiles

Pulseaudio is usually installed with default options to make it work with most hardware.

But settings can be tuned for better sound-quality. Adjust the following settings in your daemon.conf:

resample-method = soxr-vhq
avoid-resampling = yes 
flat-volumes = no 
high-priority = yes
realtime-scheduling = yes
default-sample-channels = 2
default-sample-rate = 96000
alternate-sample-rate = 48000 
default-sample-format = float32le

The two sample rate settings can be adjusted to suit your hardware configuration.

Also the sample-format can also be u8, s16le, s16be, s24le, s24be, s24-32le, s24-32be, s32le, s32be float32le, float32be, ulaw, alaw.

resample-method can be
