Yep. It's so frustrating what all the mobile operating system based streamers do to our audio signals. It's all resampled to 48khz because the OS inserts itself into the audio workflow in case it needs to send audio from other sources, like a notification, phone call, or command feedback "ding".
The strange thing is that the 44.1kHz can be forced only in one setting. I've got a JTech device inserted that extracts an optical and RCA connection, but it has a manual switch on it. If it's in "5.1" mode, KODI on the Shield can force 44.1kHz for music files and it works as well as being able to convert everything to Dolby Digital and DTS that the Lexicon can then use.
The problem is that in that position, the JTech device will not pass a Dolby Atmos signal so you have to manually switch it back to "TV" mode to get Atmos and TrueHD, etc. working again. But then the 44.1kHz switch doesn't work anymore for some unknown reason. I verified that it's not just forcing everything to 44.1kHz. If I change the setting to 48kHz in KODI, it goes to 48kHz immediately. So I don't understand how it's able to function in one mode, but not the other. KODI can still send the Lexicon Dolby Digital or DTS in that "TV" mode, just not 44.1kHz audio. It's very strange.
I'm going to have to just send the RCA outputs to the Lexicon instead of my Carver Sonic Holography unit and then feed the Carver the Zone2/Record outputs from the Lexicon. Then, if I want to use Panorama mode, I'll switch to the analog input and if I want to hear "5.1 Logic 7" or "DTS Logic 7" I'll switch to the optical input. It's not ideal (the Lexicon will auto-switch modes if it's given the proper inputs), but at least it would work.
Overall, the Lexicon sounded quite good in Logic7, even fed Atmos music as 5.1, it got most of the rear information correct. It did choke on Alan Parsons' ON AIR album on the last "Blue Blue Sky" track in THX 5.1 mode (doesn't use rear speakers separately) in that as the guy singing moves to the right side of the room, it does some weird echo/cut out thing like it's having an amplifier bad connection or something. It did it if I used direct DTS or converted to Dolby Digital and I confirmed the track played correctly when sent directly to my Marantz 7012 with the Auromatic upmixer used (It doesn't use rears either) or turning off rears and playing DTS directly (how the track was meant to be played in 5.1). So it's not any amplifier issue. That's kind of sad a $5000 processor considered near top of the line in 1999 can't play that track correctly (it does better in Logic7 mode, but there's still some slight anomaly in that spot).
I compared Panorama with Logic7 after calibrating both. There's a definite tonal difference. Panorama seems "heavier" in the mid-bass or somewhere in that vicinity, but even though it seems "clearer" in Logic7, I kind of miss the bass just the same. Imaging seems oddly similar with a calibrated Panorama imaging in 360 degrees, similar to when I tried Carver's Sonic Holography in Multi-Channel Stereo mode after I got all the speakers aligned just so except that SH doesn't sound good with every song in that mode, but Panorama seems acceptable, at least, all the time so far.
Panorama, after making some adjustments, does reasonably well simulating Binaural Headphone tricks with my Zucharelli Holophonics CD. It's not perfect, but you can definitely hear the effect. I got close with Sonic Holography in multichannel stereo mode as well, but I think Panorama works slightly better, but it's not night and day like some have told me in the past. There's some settings to make Panorama less picky (you can set it to sit off center, for example or change the relative speaker angle whereas it's fixed on Carver), but it still requires precision alignment to sound its best so they're not as different as I imagined either.
