Default Why do mp3s and audio CDs sound like crap on my PS3?

Could it be my TV or perhaps the sound settings on my system?

I get this wierd fuzz when it plays CDs and mp3s and even music that plays in the background when you select a demo game. What the frick?

In game audio is fine, though.

I've never had a problem playing audio, whether it be a copied file from CD or an actual CD itself. Might check your cables, not sure what's causing your problem. Maybe the CD's are scratched or dirty?

Can you give us more details? how do you have your audio hooked up? (RCA, Optical, HDMI) Is this audio through your tv speakers or do you have a home theater setup? etc?

combination speakers + cables most likely.. tv speakers aren't really geared for music, and have probably seen abuse from loud movie playing..

Which is probably correct... Go composite cables with crappy TV, for the win!

During music playback push triangle and go to the volume setting. If it's adjusted above normal it could cause this problem.

Also found this - the XMB defaults to 48 kHz PCM output, meaning it upsamples CD's and probably MP3's and the background music, so you might consider disabling 48 kHz for 44.1 kHz.

You mean oversamples, not upsamples. It actually doesn't though with an analog audio output as BBM is using. In the case of HDMI, it might conceivably take the 44.1kHz sampled CD, perform a D to A conversion, and then resample it at 48kHz to digitize it prior to output over optical or HDMI. While this may sound like it has the potential to degrade the audio, in theory and practice it won't as long as you are sampling at over the nyquist rate (and in the case of oversampling you are).

Edit: even taking a 48kHz signal, performing D to A, and then resampling at 44.1 kHz shouldn't provide discernible results. The reason for sampling at 48kHz or even 44.1kHz rather than the theoretically acceptable 40kHz is that it allows the use of cheaper anti-aliasing filters.

The use of 96 or 192kHz sampling rates is overkill and in reality 16-bit is plenty sufficient.
