Hi all,

Any news regarding the audio issues ? I tried to set the output volume down to ~50% but to no avail.

As soon as I start playing Serious Sam Second Encounter for example, audio issues kick in (loud static noise).

Exiting the game is the only way I found to make it stop.

Am I doing something wrong ?

Cheers, Magic Sam

Have you also muted the microphone inputs in alsamixer? I wonder also, how you set the game volume to 50%; is there a system app that sets some volume on some system or other, or did you use pavucontol or alsamixer for that?

@EvilDragon : could you please tell me how to disable microphone input (I only found the mute check box in the sound preferences) ?

Nevermind @EvilDragon , I managed to disable microphone input with alsamixer :)

I'm afraid I don't have the technical skills required to work on the audio driver. Are there any other tasks in need of a system administrator ? I can write Bash scripts, and simple Python scripts too (not object oriented).

I'm willing to do my fair share of work, this is why I pre-pre-ordered :)

Cheers, Magic Sam

I just left clicked on the speakers icon in the Mate taskbar, and lowered the output volume to ~50%. Alsamixer on the CLI reports the volume is down to 49%.

Hi all,

Looks like the poor battery performance and the overheating issue (at least on my unit) are somehow related. I believe the system is drawing too much juice out of the battery, causing it to heat up.

Is my assumption correct-ish ?

As mentioned before: this does not disable the audio stream for the microphone but only mutes it. This can improve things but not fix them.
Disabling the audio stream is only possible by poking a register of the Palmas Chip directly at the moment.

Well, it could be that something is defective on your unit drawing more Power than it should.

You could try to let the unit sit around for an hour doing nothing (with keyboard brightness disabled and screen to lowest brightness so we have the same comparison base) to see how much the battery goes down during that time period.

Also, you can run htop to see if there's a suspicious program / task running that hogs the CPU.
(just don't run htop while doing the battery consumption test, as htop itself needs CPU time as well, so the comparison would be off)

Plain old top only updates every three seconds rather than every second like htop does. It still uses some power, but a lot less.

If you want something that uses even less power then I suppose you could so something like: 'while true; do ps -ef --sort %cpu; sleep 10; done'. In fact if it's something regular then just doing the one 'ps -ef --sort cputime' might well show it
