Has anyone else noticed frequent audio interruptions using the remote headphone jack, but only when the Roku is on 5GHz Wi-Fi (as opposed to 2.4GHz)? Wanted to see if this is a known problem or if I should do further testing on my end.
(Note that my Roku phone app private listening does not have these drop-outs, though it can have a different issue with audio out of sync depending on location and router being used. AFAIK remote headphone jack works over Wi-Fi Direct between the Roku and remote without going through the router, though the connection shares the same Wi-Fi channel as the router since the Roku has to re-use the same radio. In contrast, phone app private listening audio is sent over the router connection.)
Anyways, I tried remote headphone jack private listening a couple weeks back at 2 houses, using combinations of various enhanced remotes with headphone jack and the 2017 Ultra, 2016 Ultra, 4K Stick+, HD Stick, Roku 3, and 2017 TCL 4K Roku TV's. Half were on OS 7.7 at the time, but I can re-try on OS 8.0 after today.
In most instances I heard more audio stuttering when the Roku was on 5GHz. Which is strange since 2.4GHz definitely has more congestion at both houses (the usual combination of having more 2.4 signals from neighbors et al, less channels to avoid overlap, and having those signals travel further into other homes). In general, speed tests on 2.4 show random dips whereas 5 is usually stable. Interestingly, Miracast screen mirroring (which also normally works over Wi-Fi Direct) with the Roku on 2.4 shows a few anomalies here and there, but stable on 5.
Hmm, both houses happen to use the same Asus AC router. Perhaps I should do more testing with other routers/locations...
I have *always* had audio dropouts when using headphones attached to my Roku 3 remote. Gave up on it a long time ago.

Did the Roku 3 use a different technology (i.e. bluetooth) to send audio to the headphone jack on the remote?
I've been using the headphone jack on for more than a year with my Roku3 and never had a problem. But a couple of weeks ago I "upgraded" to the 2017 Ultra and have been getting audio drops frequently (maybe every 10 minutes). The Roku is hardwired. Not sure how the remote is connected to the Ultra (is there a way to tell?).
