Hi JYA,


I'm using ALSA, and using your repository. The trouble I'm having is that the 
delay is not consistent - sometimes its spot-on, while the worst I've had is 
120ms, and usually it's between 50 and 80ms. Video is via GT220 HDMI, but 
audio is going out through the motherboard S/PDIF connector. Between the on-
board sound card, on-board HDMI, and GT220 card I have more audio output 
options available in Myth than I can shake a proverbial at. Have tried a 
variety of them and it is always the same.
