Hey all with no sound. I found a fix. I have had no sound on MSNBC. I tried uninstalling / reinstalling, clearing the cache, killing to app and still no sound. Then I did one easy thing, while on MSNBC and connected to Chromecast, I changed to HGTV and HGTV had sound. Then I changed back to MSNBC and poof I had sound. Not sure if it will work for you. Since there is no customer support I just kept trying things. Next may be a new channel supplier. Hope this helps.
