Any time you’ve got audio configured and working properly, then the configfiles for that should be removed or updated in ~/.pulse/. If this is where your pulse config lives, then in there look for any settings for the HDMI-Audio, its driver and the device itself. If the settings on the HDMI device were already correct, then you can normally let the config-files in ~/.pulse/ match those in the settings. If the HDMI-Audio driver was initially configured, that probably already exists as well and/or you can drop those values in ~/.pulse/. I imagine they only need to be modified or updated if you’ve added something to the device and/or for whatever reason the device was not reporting HDMI audio when the system was initially started. If you haven’t added anything, then the HDMI-Audio-device name that the configfiles expect will be the device-name itself, e.g. HDMI-Audio-HDMIHD5682. Also, there is no need to have a device-name for the HDMI-Audio even if you did create one and do not use the HDMI-Audio-Device property of the device. In this case, I would use all zeroes, e.g. HDMI-Audio-HDMI0. However, if you do set up the device properly, you should set the HDMI-Audio-Device property on it to the same value you would use in the configfiles. If that property is not set, then a value of 0 will cause all audio in HDMI mode to return to the one sound card.
Remove the config files for the HDMI-Audio-Driver, HDMI-Audio and HDA ATI HDMI device from ~/.pulse/. Remove any config files that it finds there. In fact, purge the config files for all devices related to HDMI audio so that even if the HDMI-Audio-Driver, HDMI-Audio and HDMI-Audio-HDMIHD5682 were configured, they will re-create the config files with the defaults you’d expect.
