Outputunderrun is when there is no data left to be output - this trigger rebuffering. Interesting the rebuffering threshold is 80000 - I thought it would be higher but it took a long time for even When rebuffering occurs, the stream has stalled (i.e. 4 secs to go from 150 to 3069, 20 secs when data received is still only 3069) - it is not being filled up and in the end LMS gives up after a timeout. This means the "buffering" issues is not in LMS, but in the network - somewhere - local LAN, modem, ISP, CDN, station and so it may not be fixable. Using LMS to play the station and using LMS measure/settings turned off (e.g. proxied streaming) can only mitigate the problem - reduce the impact on listening but cannot eliminate it. Since you can do nothing about ISP, CDN or station - all you can do is to investigate to see if it is an issue with your network. You should spend a little bit of time investigating the issue to check is there something obvious. The problem can be in the network hardware or the use of the network. Check common equipment (e.g. dodgy power barrel connection on switch which gets occasionally knocked by cat). A problem with an audio stream is obvious (gap in audio) whereas same problem would not be noticeable on a webpage display or a file transfer If the issue is network usage - then is it caused by - a whole network event (e.g. network storms, big traffic upload/download, DHCP leases expiring) - isolated issues such as the loss of a single TCP ACK packet. ------------------------------------------------------------------------ bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=116117 _______________________________________________ Squeezecenter mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/squeezecenter
