How to fix no sound or audio from HBO Max channel – other apps are fine
I'm able tp log onto the Roku HBO Max app, but there is no audio for anything I try to play. All of our other Roku apps have sound (Hulu, Prime, Netflix, etc). I also confirmed that there are no issues with HBO Max in general because we were able to watch it on XBox and had no audio issues. We tried restarting the Roku and even adding a new HBO Max profile. No luck. I believe this was pushed out just today. I'm thinking this new app has a flaw. Hopefully, someone sees this at Roku and pushes out a fix for the audio issue. Thanks.
Hello. I resolved the issue myself. I searched for just general audio issues in the roku community and found this.
Go to Settings -> Audio -> HDMI -> and set to PCM - Stereo.
What was weird for us is the audo issue was only affecting the new HBO Max app and the audio in the older apps worked fine. I am thinking that maybe some of the newer apps require different audio settings. FYI, the sound is also working in our older apps with the PCM - Stereo setting. The setting we had previously was Auto detect
