I've recently purchased and wired up my Audiolab MDAC. Very pleased, however, now that I have switched from having the audio fed directly from the TV, to hooking the sky box directly to the DAC, the audio cuts out intermittently. It might only be for a millisecond every couple of minutes, but is getting to be annoying, especially when I had no problems prior to getting the DAC. Does anyone know how to resolve this issue? Thanks
