Using Roku through Sony AV receiver
Roku stick plugged in to HDMI in on receiver. Then HDMI cable in ARC on TV and receiver. Worked great. And then suddenly stopped. Works fine if I plug the stick directly into HDMI port on TV, but...

You didnt mention your Roku stick model # or firmware version (Settings/System/About).
If JWS9518 's suggestions don't restore surround sound, check the following:
1) If highlighting Settings/Audio/Digital output format/Auto = Dolby Atmos, Dolby Digital+, DD+ then you should get 5.1 from most services - if this only says Dolby Digital or DD (Or Stereo) then you wont get 5.1/surround from most apps/services - power off all devices for 3 minutes and check again
2) Make sure your Sony AVR (model unknown) doesnt have a sound/processing mode applied - verify Pure/Direct (disable Dolby Surround/AFD/etc, at least temporarily)
3) Your TV (brand/model unknown) should be able to pass DD/DD+ (Dolby Digital/Dolby Digital Plus; AC3/EAC3) which streaming services/apps use for 5.1 from HDMI to ARC/eARC if its even remotely recent - you might want to try this again making sure to adjust any relevant HDMI/ARC/eARC audio settings in the TV.
