Try the following.
In
/usr/share/pulseaudio/daemon.conf
edit the following lines, then they should look like.
resample-method = src-sinc-best-quality
default-sample-format = s16le
default-sample-rate = 48000
And add the use_ucm = 0 ched = 0 option to
/usr/share/pulseaudio/default.pa
load-module module-udev-detect use_ucm = 0 tsched = 0
Then restart Pulseaudio
pulseaudio-k
pulseaudio - start
Sorry for my bad english.
