Media playback speed problem

[Bernard Peek]

I'm running Mint 64-bit 12 on an Intel i5 quad-core box. Within the last
week or two something has changed and now I can't play any media files
at normal speed. MP3 & flac sound, MP4 video and BBC iPlayer audio all
run at several times normal speed apparently only limited by the rate my
machine can load the data. Does anyone know if any recent Mint updates
might have borked the system?

I have run into this problem before.
I fixed the problem by setting pulseaudio to 48000 Hz.
In /etc/pulse/daemon.conf
Change
#default-sample-rate = 44100
default-sample-rate = 48000

Restart the PC, and see if that helps.

The reason behind this, is PC based sound cards prefer 48000 Hz, and
pulseaudio can get confused sometimes when using 44100 Hz.
Pulseaudio will resample your mp3s so that they match the 48000 Hz of
the sound card.

Why would you restart the PC?

Why not just restart the pulseaudio daemon?

Thanks James. That worked.
