Intermittant Chirpy or Pulsing Audio - Roku Ultra 2020 version
Roku Ultra (2020) connected to LG Oled TV via HDMI. Using HDMI Cable with Ethernet to pass audio via ARC to Marantz SR5007.
On Amazon Prime, audio will play correctly 1 time. Then, when the same show is selected, the audio either chirps rapidly or pulses on and off. Any prime video selected after that stays chirpy or pulses.
Other apps seem to play fine. For example, ROKU CHANNEL plays audio correctly.
Restarting ROKU does not have any effect. Have looked for an applicable audio setting but have not found one.
