I recently just upgraded to a Pandora premium member, hoping for better sound quality when chrome casting to my TCL TV (Roku Interface) or playing Pandora from the app on the TCL TV. The sound quality when casting from my iPhone is muffled, not clear, and quite bad (and yes I have put the quality of the sound on High through the settings). I have a iPhone SE (2020). I also have tried the Pandora App on the TCL TV (Roku Interface), again very bad sound quality and it is not very clear. Only when I chrome cast from my desktop computer, the sound quality is amazing! Desktop computer is connected thru an ethernet cable. All other devices are wireless. Yamaha sound system is being utilized for the TV and front 3 speakers are wired, and 2 rear speakers are wireless and run on 2.4 ghz. Internet at home uses 5 ghz.
Any ideas on how to get good sound quality using the Pandora Roku app or when chrome casting from the iPhone? These are the more convenient devices when playing music at home.
