Hi All, I just want to say I upgraded to kernel 2.6.36 today and still miss the first 0.5seconds or so of the sound output. Again I have ruled out player - mplayer, aplay and audacious all do it I have ruled out source format - both flac and the wav decoded version have the same problem. I have also ruled out physical connection to the AVR, both HDMI and SPDIF exhibit the same problem. Any ideas?
