XM will not unmute after standby
When comming out of standby, the XM box will not unmute and send audio out of it's audio jacks. RR is unmuting the line-in fine, I tested it by unplugging the XM box and plugging in another audio source, and the test audio comes through line-in just fine. Also, it appears the XM box is communicating with RR normally with no error messages and all XM channels load and appear normal in RR, with the programs showing and changing, and I can change stations like normal, so I feel RR is talking to XM just fine.
I can't seem to do anything to make it unmute, restarting RR, rebooting the PC, cycling power on XM, or any combination. The only way I can get the XM to unmute itself is to re-install RR. Then it works fine for several standby cycles, and then the XM box mysteriously mutes itself and won't unmute. When it does initially work, the RR volume and mute buttons work fine with XM and all other audio sources.
I just installed a new laptop (ASUS EEEPC) for my carputer, upgraded FROM Vista to XP, and updated my RR, which was an older 2007 version. I also added a USB sound card, but I don't think this is the problem, since I can plug audio into the USB soundcard from another source, and it's fine. Before the computer change and RR update, everything had been fine, running for a couple years.
Help, this is about to make me nuts!
Edit - Just thinking, is there a chance it's my XM box? I had it off for a few months, and I had to do a reactivation to make it work. But all that seemed to be fine, until it quit unmuting. I'm also thinking the problem may only occur when XM was active when it went into standby. Could this be some kind of inverted mute/unmute problem? I think I will go test for that. Nope, no audio ever out of the XM box, unless I start over and reload the RR software. Then the cycle repeats...
