View Full Version : Internet Radio and Digital Outputs

I've had my squeezebox for about 3 days now, and I think it is fantastic. I
do have an issue with internet radio that I hope can be addressed.



I have a pretty high end Amp, A Yamaha RV-X1, and it apparently has some
issues with internet streams when using the digital outputs (either coax or
optical). Let me provide some background first. The Yamaha onboard DACs
will interpret MP3s from my library as coming over as PCM at 44.1 kHz, and
it will let me use any of the numerous DSP modes (live concert, stadium,
arena.) to utilize the surround speakers. Some radio stations will come
over as PCM 44.1 kHz as well, but others come over as PCM with an unknown
sample frequency. When the sample frequency is unknown, the DSP modes will
not work, and I can only get stereo.



I'm not sure it is an issue with the Squeezebox, Slimserver, or the stream
source, but I would think it is with the Squeezebox - after all, it should
output a 44.1 kHz sample, shouldn't it?



I'm using Win2k for Slimserver, ver 5.1.1, and other than the digital output
issue, everything seems fine.

A stream that reports an unknown sample frequency is

Thanks for any insight,

If that's what it gets for input, sure.

That's a 22 kHz 56 kb/s stream. I'm pretty sure the Sqbx doesn't
resample, so it's likely coming out at 22 kHz. Your receiver may report
this as "unknown" but that's misleading. If the frequency were truly
unknown, you wouldn't hear a recognizable output. The DAC has to lock
onto something.

Not every stream on the net is 44.1 kHz.
