Just for trouble shooting purposes. Is is possible to connect your PC to SA30 analogue input, e.g. CD and use analog direct. @AleisterCrumpet reported in ARC: audio and video are not in sync, ref#52 - #4 by AleisterCrumpet there is no delay if he used analogue input icw analog direct. I was wondering if the same delay was occurring once you used this setup. If you cannot connect it through the analogue input, that is no problem. I’ll create the ticket without this information.
