So, Adrian, you're saying this 93% pitch thing only applies when playing
Flacs through SB's DAC... when doing digital outs you leave it at 100%?

I'm playing Flacs via the digital out and can hear a difference when I drop
the pitch--but can't say it's "better" or worse for that matter. If it's
not 100% pitch though my receiver's DAC resets every time--and periodically
suffers the L/R swap flaw.

I'm getting confused.

Thanks,
Phillip

No, appologies if I confused you. The DAC bit is unrelated, just wanted to say that Squeezebox can play flacs very well at the
correct pitch.

For the moment (until the bug is fixed):
1) set the squeezebox to 100% pitch [so that the server stores this as the setting for the player]
2) reset the squeezebox - hold down power off on the remote for a while
3) happily flacs and *never* change the pitch again!!!

Re the L/R problem. This appears to occur when the Squeezebox changes from PCM to MP3 mode. If you are a regular player user of
mp3s and are able to stream to the squeezebox as pcm without dropouts, then I would recommend configuring the server to decode the
mp3s, rather than leaving the squeezebox to do it. I think we concluded a while back that something like the following would work:

mp3 wav
[lame] --mp3input --decode -t --silent $FILE$ -

(NB I've just made this up again and not taken it from a working config as I don't have any mp3s and so don't use it!)

I went and looked up the original notes for the pitch control. Dean
specifically stated even then that it was experimental and ONLY worked for MP3.
Clearly it then suffered from obscurity; the lack of support for non-mp3 was
forgotten. Pitch control is clearly NOT VALID for FLAC. The way to deal with
this for now is to set it back to 100%, then unplug your squeezebox and plug it
back in. After the reboot, it should play at its proper speed.
