Hi,
I've been using various squeezebox devices for years, I helped work on the software many years ago back in the Slim Devices days. I have a SliMP3 that is still going strong. Unfortunately my SB1/SBG seems to have developed a hardware fault. It will look like its starting to play audio, the display time advances but no audio from the RCA, headphone socket, optical or digital outputs.
Looking around with a scope, the 5V, 3.3V and 2.5V power rails are fine, I see a burst of data from the CPU to the DAC on the serial connection which then stops. There is activity on the i2c bus from the CPU to the DAC. The digital outputs and analogue outputs look like they never get enabled by the DAC. It does look like the audio is buffered to the DAC but never starts playing. The server increments the play time on the display but the track never finishes and it never advances to the next track.
Has anyone ever seen this before? Is there pinout information on the unpopulated headers on the SB1/SBG? Anything else I could do to try and debug it? Any pointers appreciated. I can't see much information on the older devices unfortunately.
Cheers,
Richard
