Category: audio output problems Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Pete (pete4abw) Assigned to: Nobody/Anonymous (nobody) Summary: shn files don't play properly Initial Comment: xine-lib-1.1.8 kernel 2.6.22.6 AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ Using xine, gxine, amarok, etc., shorten files simply do not play. Output is short (< 1 seconds) blips of unintelligible sounds. Everything is in slow motion. Blip, second pause, blip, second pause, blip.....
