I have a hokey workaround of a recording of two seconds of silence I made in Audacity, which I put in my favorites and always put first in the playlist. Gapless transitions are fine. I think the UMC-200 is just taking too long to come out of the muted state for the first song played.
Has anyone reported this one?
I have some more information to report on this problem. Just to recap, with S/PDIF input to the UMC-200, I was getting the first second or two of the first song on a playlist cut off, and as a workaround I was putting a two-second recording of silence as the first song in each playlist. This prevents the chopping-off of the sound at the beginning of the first actual music track.
Unfortunately, the problem is not limited to the first song of a playlist. If later songs have a silent portion at the beginning of about 200 msec or less, these additional songs will have their beginning cut off too, though not quite as rudely as the first song of the playlist. This became very noticeable on the album Get Together - The Essential Youngbloods
, for which it happened on every song. Very annoying.
Just a couple of days ago, I ran into another related problem. The playlist reached the end of a song, then when it was time to play the next one, the sound just dropped out altogether, then came back in, then dropped out again, then came back in. At first I thought my router might be having problems, as it's a wired network so no problem with wi-fi dropouts. Then I had a look at the song that caused the problem. I was listening to a playlist of randomly-chosen songs, and the culprit was a song ripped from a DVD-A, having 24/96 resolution. The transition from 16/44.1 to 24/96 caused a major dropout, not just a minor glitch. I tried this a second time and it is completely repeatable.
For this reason, if you're using S/PDIF with any regularity, I recommend not
getting the UMC-200 until such time as they fix the problem.
I decided to see if this happened using HDMI, so I put some music on my laptop and hooked its HDMI output to one of the UMC-200 HDMI inputs. There was no problem, either with truncating the beginning of the first song, or with changing resolutions and sample rates on the fly with a playlist of mixed file types.
