No audio over HDMI - UHD730

[Risto82]

PC specs:

Motherboard: Biostar Z590MHP

CPU: intel i5 11400

GPU: intel i5 integrated UHD730

RAM: 16MB, 3200

SSD: PC SN740 NVMe WD 256GB

Windows 10. 64bit.

Problem:

No audio when PC is connected to TV via AVR over HDMI. Video works.

Notes:

Audio works when headphones are connected to PC via 3.5 mm jack. So integrated audio card works.

PC and AVR are connected directly by HDMI cord, no other connections in between. Audio works with other PC-s (laptops) connected behind the same HDMI. So it is not HDMI cable, connections nor AVR settings issue.

Under device manager the PC recognises AVR as monitor but not as audio device. Other PC-s connected recognise AVR both as monitor and audio device.

In BIOS HD audio is enabled.

Have tried several audio drivers: Realtek, Intel, Windows generic. Nothing works.

Have the latest graphics drivers + done a clean install of the drivers as instructed in intel forum somewhere.

All win10 updates have been done.

Have tried win11, same issue. Reverted back to win10.

Intel processor diagnostic tool: all passed.

Intel SSU report is created, but what is the relevant part I should look at in order to diagnose the problem.

Any ideas or suggestions what to try?

I have found a solution, that fixed the issue for me. I reset BIOS settings to factory settings and now it works.
