3. Disable HDMI Audio through ALSA
In some cases, you may need to disable HDMI audio at the ALSA (Advanced Linux Sound Architecture) level.

a. Edit the ALSA Configuration
You can disable HDMI audio in ALSA by editing the alsa.conf or by creating a custom file.

Create or modify the ALSA configuration file to blacklist HDMI devices:

bash
Αντιγραφή κώδικα
sudo nano /etc/modprobe.d/blacklist-hdmi.conf
Add the following lines to disable HDMI audio drivers (replace snd_hda_intel with the correct driver name if different for your setup):

Αντιγραφή κώδικα
blacklist snd_hda_codec_hdmi
blacklist snd_hda_intel
b. Rebuild the initramfs
After making changes to ALSA configuration files, you may need to rebuild the initramfs:

bash
Αντιγραφή κώδικα
sudo update-initramfs -u
Then, reboot your system for the changes to take effect.
