I agree that this would appear to indicate a server/transcoding issue.

For recent softsqueeze versions there is no transcoding it acts like
an SB2 and decodes the FLAC directly on the local machine, which
further points to a transcoding issue.

What comes out of the analogue/headphone outputs of the SB1?

Can you switch the fancy DSP off, and just use the external DAC?

There have been some comments about SS 6.x.x being unsupported 
on RH7.2 due to a broken perl build. I don't know if this could
be related, but it's probably unlikely.

For reference try "flac -version" in a command window.

I'm on flac 1.1.0.

This file defines how the transcoding is done. If you'd made
any changes to this then you could have different transcoding
going on than you had thought. You haven't edited it so this is
unlikely to be the problem.

Another interesting piece of data would be to turn the d_source debug
option on and then try to play a FLAC file. You'll see an entry in the
log looking something like:

2005-04-06 22:04:13.0769   command: [flac] -dcs --force-raw-format
--endian=little --sign=signed --skip=$START$ --until=$END$ -- $FILE$

This will confirm that the correct transcoding is happening.
