@lakotaubp Same here on 327, local playback of multiple tracks with screen off works as expected. Web based music stutters with screen off and charger unplugged.

@lakotaubp I'm an idiot, the music totally does cut off on the second track when playing locally with the screen off and charger unplugged, even with app suspension prevented in UT Tweak Tool. With charger plugged in this issue goes away. Sorry about that.

@lakotaubp My experience with this kind of issue is as follows:

• Screen off, charger unplugged, music playing from internal storage: no issues
• Screen off, charger unplugged, music streaming from internet: music stutters and stops a few seconds after screen off
• Screen off, charger plugged in, music streaming: no issues
• Screen on, music streaming: no issues

For streaming music I usually use the emby client app to stream from my jellyfin server (app supension prevented with UT Tweak Tool, but this doesn't seem very effective). I haven't tried to troubleshoot it much becuase it wasn't a huge issue for me. Lmk if I'm misunderstanding the issue you're referring to or if there is something I should test.

@pauloaugusto The links worked for me, they just bring you to the latest oxygenOS software update and the twrp page for oneplus 5.

At first when testing with a sim from a mnvo the APN settings were set incorrectly and mobile data didn't work. Editing the APN settings manually was a little weird as @Lakotaubp mentioned above, the changes didn't seem to stick. I didn't try to get it working for very long because using a different sim card from a different provider worked flawlessly without manual intervention.
On the first day after installing, the about page of system settings showed the last update as being on 7/3/73 (time and date were set correctly in the OS). After a day this changed to the correct installation date.
Overall I think this is awesome, it's my first experience with UT and I'm going to try to daily drive it. Thanks to everyone for all the hard work.
