Nines - No Sound Via HDMI ARC (Troubleshooting)
If you notice that The Nines are working on non-HDMI sources, but you can't seem to get any sound through the HDMI-ARC source, it could be due to an incorrect output format on your TV's end.
Your TV should always have it's audio output format set to "PCM" when playing The Nines via HDMI-ARC. The output format should not be set to any "Bitstream", "Dolby" or other surround sound output format
This "PCM" format stands for Pulse-Code Modulation and is a standard technology for converting analog audio into digital audio for 2 channel stereo mixes.
