I tried a different Pi 4 with a different OS image and it has the same distorted audio on the TV.

Audio hdmi raspberry pi. The 35mm audio sounds normal. The ALSA mixer has no effect on the HDMI volume. When I plug either into my computer monitor however the audio is just fine same HDMI.

The Raspberry Pi has up to three audio output modes. If your HDMI monitor or TV has built-in speakers the audio can be played over the HDMI cable but you can switch it to a set of headphones or other speakers plugged into the headphone jack. If you want sound over HDMI configtxt should have both.

Theres another setting in your bootconfigtxt that affects sound. You can switch between these modes at any time. You need them both set because hdmi_group1 tells the kernel we are using CEA mode for TVs has sound instead of DMT modefor monitors no sound and hdmi_drive2 tells the kernel to use HDMI if available.
