Digital Audio Volume Level Suddenly Very Low
As of this morning, the volume level of the digital audio output from our set-top box (Technicolor DVR: Spectrum201-T, via HDMI) is suddenly very low, which means we have to crank the TV volume way up past its normal setting to achieve a reasonable listening level. We've tried every conceivable setting on both the box and TV with no success. The digital audio volume is set to Fixed and cannot be changed. I spent an hour with a Live Chat agent but to no avail. The last option suggested was to change the HDMI cable, which I did, but it didn't help. Of course, we had been through the other options, including cold reboot and wait 20 minutes before turning the box back on.
As I mentioned, the problem began this morning. We're wondering: 1) if anyone else with this same equipment has experienced this recently; 2) whether there's some way to escalate the issue resolution; and 3) do we simply need to request new equipment?
All feedback is welcome.
