Hello all,
As stated in the title, I'm looking for a way to disable HDMI audio output.
My goal is to help visual-impaired and blind people to keep their sound
working on the laptop output even if the HDMI output doesn't work. Blind
people only rely on speech synthesis and so PulseAudio to use their
computer.
Before asking you this question I've made lot of search on the internet
and I've tried to blacklist HDMI sound driver like this:
blacklist snd_hda_codec_hdmi
Unfortunately it doesn't work. If I add this line:
install snd_hda_codec_hdmi /bin/false
It disables HDMI but it no longer possible to change the volume both
through PulseAudio or alsamixer.
Do you know how to disable HDMI audio output ? (I'm not an expert in
sound configuration)
Thanks in advance.
Best regards,
Alex.
