I have been doing further testing on this and now have some logs that I hope might show something to somebody who knows what they are looking at.
I have tested several devices now, JRiver ID, d-link DSM-320 and a WD TV Live.
NONE of these give me gapless playback all the time, by gapless I mean less than 1 second gap. Since the ID is wireless that could introduce a bigger gap so I didn't test a lot with that, but the d-link and WD seem to exhibit the same issue.
What I have found so far is that if I reset the dsm-320 and then start MC I initially get "gapless" playback, but after a little while I start getting gaps. After that I seem to get gaps until I power off the dsm-320 and close and restart MC.
I am attaching 3 logs.
1) A log showing gapless playback between two mp3 tracks.
2) A log showing gapless playback between the first two tracks, but I let play continue. After a few tracks a gap of several seconds started to happen. I believe it started at the change to "Young Lust".
3) A log with gapped playback between the two tracks
All testing is done pushing from MC to the device and with mp3 files so no conversion is necessary.
I did some testing with Nathan and we couldn't get the gap issue at his place with the same version on MC using a dsm-320, but we are going to put one at his house for a bit longer to test further.
Do the logs show anything that might point to the issue???
Thanks
