Hi Ralphy, i try to run squeezeslave (latest version) on my eee pc 901 (intel atom 32bit) on ubuntu 11.04. Unfortunately squeezeslave freezes from time to time, escpecially when changing tracks, reaching the end of a playlist etc. I tried several versions of squeezebox server and also a switched from pulseaudio to pure ALSA without success... I started to investigate a little bit; i compiled squeezeslave with full debug symbols and made some debugging. When squeezeslave freezes i get following information from a backtrace of all running threads of squeezeslave:

Debug output is quite useless, because the printfs are not flushed and when everything freezes it lacks entries. Some more information: Kernel 2.6.38-8-generic, *multicore* as hyperthreaded, i686/x86 not 64bit. Audio "HDA Intel"/"Realtek ALC269". I hope we could figure out whats wrong.... With best regard, Robinson. -- gonzo255 ------------------------------------------------------------------------ gonzo255's Profile: http://forums.slimdevices.com/member.php?userid=48250 View this thread: http://forums.slimdevices.com/showthread.php?t=83362 _______________________________________________ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/discuss
