View Full Version : Browser refresh causes AAC cut-offs (5.4.1)

I reported this issue back in November when 5.4.0 came out and had hoped it
would be better in 5.4.1 but I still have the same problem
(http://lists.slimdevices.com/archives/discuss/2004-November/038700.html)

System is:- G4 iMac OSX 10.3.8, SlimServer 5.4.1 using iTunes 4.7.1,
Squeezebox

I get audio cut-offs on AAC files when the browser displaying the SlimServer
web interface does a refresh * either the default 30 second browser refresh
or a manual refresh.

The problem happens with Safari, Firefox and Internet Explorer.

The problem happens when playing an AAC file * it doesnıt appear to happen
when playing a MP3 file.

The problem doesnıt appear to be related to the size of playlist * it
happens with one file in the playlist.

Looking at the Mac activity monitor, when a refresh happens, the browser
seems to grab well over 50% of the real time and the CPU maxes out.

The cut-offs only appear to happen when the SlimServer web interface is
refreshed * I donıt get cut-offs when refreshing another web-pages.

The debug logs shows the following when a cut-off occurs:
2005-03-20 17:43:00.9477 00:04:20:05:04:d6: Underrun while this mode: play

A workaround is obviously not to have the web-browser pointing at the
SlimServer when Iım listening to music but Iıd rather not be forced to do
this * I would have thought a G4 Mac would have more than enough horsepower
to run SlimServer playing AAC files and do a browser refresh.

Iıd rather not try SlimServer 6 as a friend tells me it is still quite
buggy.

Any ideas? Iım happy to collect more debug information if someone could tell
me what is needed...

Michael - this issue has been addressed for 6.0. I do suggest you give it a
try. We can only make 6.0 better if we know the issues with it, and right now
there are many people using it without any problems.

Thanks.

Michael - has the server finished scanning? There is also a cleanup task
which runs right after scanning, depending on how large your collection is,
it might take a few minutes.
