Q990C Source Selection not working

[jb1677]

Integration seems to work well for power on/off and volume up/down but I cant seem to get it to change sources. Anyone else seen this issue, any workarounds or fixes?

It is a problem on the SmartThings side :/

Ugh, was hoping it was something that would actually be solvable!!! I will not hold my breath waiting for them to fix it.... breaking things is why I left that ecosystem in the first place! I should have chosen a better soundbar as to not get sucked back into that mess!

It might be possible to solve it someday after some additional investigation. Also, from HA 2025.4 Samsung soundbars will work with built-in SmartThings integration
