I've noticed a reproducable playback issue on two listener machines I'm using for testing: a Duron 800 with a cheap Avance soundcard and a P3-900 laptop with builtin audio. I'm testing across a LAN so bandwidth isn't an issue. Stream is a 32kbps mp3 and all machines are set at 128kbps upload/download.
I connect the machines and they playback fine. Then I open a web browser and load a graphics-intensive page (e.g. http://abcnews.go.com/
). During page-loading, and if I scroll the loaded page rapidly up/down, the playback stutters. This is most noticeable using Firefox 1.5, but also occurs (to a lesser degree) with IE6.
As an experiment, I tried changing the priority of the streamer.exe process on the listening machines (I have Windows 2000 on both). Increasing the priority from 'normal' to 'above normal' cures the stuttering issue. Playback remains stable regardless what I do in the web browser.
I should add that I don't experience this issue on a third test machine -- a higher-end P4. And also, the two 'stuttering' test machines have no issues with other streaming audio sources, e.g. http://www.cbc.ca/listen/index.html
Any ideas, anyone? Changing the priority of a running streamer.exe process isn't a solution to the issue, but perhaps provides a clue as to the cause of the problem.
