I am auditioning a HIfi Rose 150B and think it sounds good but there are some audio dropouts when connected to my LG OLED tv by hdmi arc.
This is an instance where it might be the cable - especially so if it's a long run. Try a swap if you have a second HDMI cable handy. As a last resort, here's a link to a list of HDMI cables that were evaluated using a machine that is built to test for adherence to industry specs.
Most TVs have optical digital output nowadays. Another option would be to connect your TV's optical digital output directly to the H590.
I also suggest contacting Rose to see if they've encountered this problem before and have a fix via firmware / software update.
Hope this helps.
