Hmmh.snd_bcm2835.enable_hdmi=1 relates to the legacy audio driver. As you're loading vc4-kms-v3d that won't be enabled - HDMI audio and video are inherently connected (audio goes in the video blanking periods)That's not the subject!
ive done testing, and found that you dont need any config changes
simply booting with the hdmi unplugged is enough to reduce the power usage
The Q is if these overlay options actually do what they are designed for. The existence of that cmdline option could point to a
flaw in the system.
You can confirm for yourself with "aplay -l" to list the audio devices on the system.
I thought the legacy driver would be turned off with:
Code:
dtparam=audio=offAnd I'd also assume that if I have a different GPU driver - also in charge for the audio part - in the game, that the legacy driver for HDMI audio should be disabled by the system to avoid concurrent operation. But again. The confusing part is what's shown in /proc/cmdline. And that after turning all related params to "off". The entry still keeps showing "on".
