View Full Version : Gaps in playback

I don't have the web interface active when I've had a break happen and I'm
not rescanning (unless it happens automatically at random intervals). The
buffer just drains and doesn't begin to fill until a second or two after the
music stops. As far as I know, there is nothing else using my wireless
network at that time. I have 70-80% signal level at the Squeezebox. I
can't verify the 100% CPU because I've never been near the server when it
happens. It's not a constant thing -- maybe once every 30 minutes to an
hour or so for me.

I'm running 5.1.6 (2.3) on 667Mhz PC running XP home.

This is annoying, but so is the "Pause" problem that I'm seeing. Streaming
flac->wav, 30 second pause causes no problem, but a 32 second pause empties
the buffer and won't resume until I issue some play-related command.
Streaming MP3, the safe period was longer, of course.

This is definitely not right and is a serious problem. Intermittent
networks, usually wireless interruptions, are the most common cause for

The CPU overhead problem is a new one for me, but could be related to
loading from scanning your music library or heavy load on the web
interface. Is there a reliable way to reproduce this problem?
