No more audio through HDMI in 22.04.1 LTS

Ok, I've been running Ubuntu 22.04 for a while now. Everything worked fine until an update a few months ago.

Now, when I am connect and HDMI cable to my laptop, the audio will always use the internal speakers.

Under settings / Sound, I see the HDMI output device. If select it, and use the "test" feature, then the sound comes out of the "built-in" speakers (instead of the HDMI) and moving the volume control has no effect.

Selecting "build-in speakers" works as expected.

I think this is the audio controller:

0000:00:1f.3 Multimedia audio controller: Intel Corporation Tiger Lake-LP Smart Sound Technology Audio Controller (rev 20)
    Subsystem: Lenovo Tiger Lake-LP Smart Sound Technology Audio Controller
    Flags: bus master, fast devsel, latency 32, IRQ 189, IOMMU group 14
    Memory at 601f270000 (64-bit, non-prefetchable) [size=16K]
    Memory at 601f000000 (64-bit, non-prefetchable) [size=1M]
    Capabilities: [50] Power Management version 3
    Capabilities: [80] Vendor Specific Information: Len=14 <?>
    Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+
    Kernel driver in use: sof-audio-pci-intel-tgl
    Kernel modules: snd_hda_intel, snd_sof_pci_intel_tgl

I am not sure what to try to get the audio "routing" to work correctly.

additional:

3.5mm Headphones work fine (sound is routed to headphones)
using bluetooth headphones, the sound is still routed to the "buildin speakers" vs the bluetooth ones.

Thanks for your help

The audio chipset has nothing to do with Bluetooth audio. The relevant question is: Are you selecting the Bluetooth audio output and the sound still being routed to the internal speakers? If so you have a problem indeed.

@ChanganAuto... that's exactly it. Audio is always routed to the internal speakers

Note. If I plug in headphones and then unplug them, I can get sound to route through the HDMI port.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
