Yeah, I'm pretty sure that the "*.1" is supposed to mean subwoofer.
Success. The adapter works.
Thanks to Jimmie (and all who participated, too)!
The LG TV I'm now using (got it when my mom passed away) also only has only a TOSLINK output for audio. When watching OTA, it does pass 5.1 , but if you are using the HDMI ports, it only outputs PCM stereo. I'm using a low end Pioneer AVR that I got from Woot, and all the HDMI ports on the Pioneer have crapped out. The analog ports, the 2 Toslink optical ports, and 2 digital coax ports, all work fine. So, I can listen to satellite TV via TV in stereo, or use digital audio direct from them to the Pioneer. Most of the time, we just listen through the TV speakers, saving the AVR audio for things like music award shows / movies, etc. If it was just the wife - she would just use the TV speakers only.
Yeah, I kind of thought that the port was only supposed to pass 5.1 for OTA. (Mine's an LG, too.)
Interestingly enough though, I was able a couple of times (back when I still had my digital AVR) to "trick" it into passing 5.1 from HDMI to its optical port.
The input of the LG had been connected to the HDMI pass-thru port of a capture box. I can't remember the exact sequence, but it had something to do with the specific order of having the computer disconnected or on standby while the capture box was still getting power to maintain the pass-thru, and then putting the DVR into Dolby from PCM.
It was quite by accident I happened to notice the Dolby logo appearing in the info banner of the LG. So I connected an optical cable from it to the TV and lo and behold, it lit up all six channels indicators on the AVR.
I've never been able to find any settings for that function in the TV's menus. I assume it's all supposed to be automatic to the TV and whatever device is connected to its HDMI port. Somehow, those automated signals must've been "blocked" by the capture device in the standby mode. Any other device connected the TV will not pass 5.1 to the optical port.
(Also, when the box was active, whle it was capturing 5.1, if I'm remembering correctly the TV's audio would then go dead until the DVR was put back into PCM mode.)
At any rate, for me at least, I'm one that doesn't tolerate audio from TV speakers for very long.
