I tried, but couldn't get that to work. Ran the S/PDIF out from the daughterboard and into the optical S/PDIF of the GTXP breakout box. Then MyHD S/PDIF. No sound. Reconfigured the GTXP in Digital Output Configuration for "Digital Audio Source." Still no sound.
So, I instead ran the optical cable directly to the receiver. Now, I get audio two ways:
1. Selecting the source on the receiver I have sound by virtue of the optical S/PDIF connection from the MyHD daughterboard when MyHD is configured for MyHD S/PDIF.
2. Selecting my usual receiver source for the computer, which is from a coaxial S/PDIF from the GTXP breakout box, and selecting PC Soundcard/Dolby Surround in MyHD config.
Both work, but each has its downside:
Optical out from the daughterboard direct to the receiver is presumably the best sound, and I'll probably never get the garbled sound, but if anything happens to interrupt the sound (e.g. changing channels) the receiver loses synch and has to regain synch to get sound again. This is attended by an annoying click!
So, I figure if I'm going to be doing any channel hopping, I'll use PC Soundcard to avoid the clicking as long as the sound is OK. If I'm watching a recording or a program and won't be changing channels or doing anything else to interrupt the stream, I can use the direct digital approach (1.).
I'm wondering if I wouldn't have trouble using MyHD optical
S/PDIF --> GTXP breakout box --> receiver S/PDIF if I used optical
output from the breakout box to the receiver, but there are only 2 optical inputs on the receiver and currently one is being used by my DVD player, the other by the MyHD daughterboard. I could remove the latter and try that, but I figure it wouldn't work. I guess I'll try to find a workaround for the soundcard's reluctance to pass through the digital information. I believe there are some GTXP forums. Their site's been down for a couple days, though.
