[flame suit on] Personally I find it unfortunate that S/PDIF was ever specified to run over coax copper in the first place. There are some who claim it's better than fiber for various reasons, but all empirical data says that optical S/PDIF is FAR more reliable, works over longer distances, and delivers measurably lower jitter at the receiver. It also inherently isolates ground offset, low frequency and EMI noise between devices. The only good reason to use coax is if you don't have an optical cable or an optical input available, which is primarily why we have the connector there. [/flame suit]
More constructively:
If you're having problems not just with Squeezebox2 but with other s/ pdif sources, then the problem could well be the cabling or your DAC. Some things to check:
- try a different cable. Video cable may have higher bandwidth and better shielding than those marketed as "digital interconnects", and definitely will have the correct 75 ohm impedance.
- check your Squeezebox2 MAC address printed on the bottom. The first SB2s produced had a bug in the coax output which could cause errors. If your MAC is 00:04:20:05:A3:FA or lower, contact [EMAIL PROTECTED] for repair.
- If neither of those narrows down the problem, then it's probably a defect in your DAC's input. I could help you troubleshoot but you'd need an oscilloscope to see what's happening in there.
