Pulse audio was a workaround to allow for audio in the early C2 days of development. It was removed due to the oversun /etc/asound.conf which resolved sound working with ALSA, at that time.
https://github.com/Fourdee/DietPi/blob/ ... #L527-L548

This has now been fixed in the kernel I believe. As the oversun workaround was no longer required, it was also removed via a dietpi-update, during patching: https://github.com/Fourdee/DietPi/blob/ ... 1334-L1341

Not clear yet if LXDE and XFCE have by default pulseaudio?
Mate is the only desktop we use, that installs Pulse audio due to it being a dependency.
Code: Select all
root@DietPi:~# apt-get install xfce4 -s | grep pulse
#Nothing, not installed
root@DietPi:~# apt-get install lxde -s | grep pulse
#Nothing, not installed

root@DietPi:~# apt-get install mate-desktop-environment -s | grep pulse

Thank you for explanation! Have Debian 's ARM 64 no environments (LXDE and XFCE) pulseaudio by default? Why Meveric installed pulseaudio?

Yes, they do NOT have pulseaudio installed by default.

I do not install pulseaudio. Even if you think I do, I do NOT.

Why you have to delete pulseaudio? Is it not included in new image Debian8 arm64, isn't it?

I have problem running CEC using libcec (via cec-client from cec-utils).
When executing cec-client -l command I get message that none device where found.
When executing any cec command with device manually provided (echo "standby 0" | cec-client -s /dev/cec) log suggest that library is writing to device but never got any response from TV (Sony bravia) - even ping ended in "not asked by controller message".

However CEC is working (even without libcec installed at all) both I kodi and I console.
I found somewhere that there is hybrid driver (sometimes reffered as aml keyboard) included in kernel that does not work with libcec.

As I understand adding hdmitx=cec0 should disable this mode, but it is not working in dietpi.

Any idea how to use cec-utils or libcec on thisi distro?

EDIT:
I broke my secondary card (cut it in half while removing from card reader) so I am not able to check on HW kernel.

However I found other solution than libcec that is working (a bit crude one may say).
There is device /dev/cec which is created by HW cec driver. It allows direct write to cec (ex. echo -n -b "\x01\x36" > /dev/cec) and read from it (ex. xxd /dev/cec). It not as reliable as libcec (read operations does not change internal buffer) nor easy to use but allow to do everything. And it is better in one case as this not close other cec connections so it does not brake kodi cec when used (libcec does)

It should be the same as any Debian Jessie image as we don't specifically change any CEC related settings, however, as I lack a CEC capable device, i'am unable to assist with CEC support at this time.

My only suggestion would be to try the official HK Ubuntu image, see if the problem persists there. That could indicate an issue with the setup and/or configuration.

I think I saw the same issues on my image. Lately I can't turn off CEC anymore which was working before. I'll try to check what have been changed, but CEC had low priority up to now since I don't use it either.

Thank you both for answers and effort. I will try HK version on other card for comparison.

Wine in DietPi...yay (any possibility of a package of that happening) or nay?

What Windows ARM64 programs are you trying to run under Linux?

Hello,

I just installed DietPi to test kodi and sickrage, both are working great, nice build. however, I'm seeing a big CPU usage because Xorg (67%) is that correct or I did some thing wrong?

thanks

Am...stupid question, forget it lol.

Was hoping to run some old office software on it. I forgot that they're not even the same architecture.

Hi,

When Kodi is idle, you should experience roughly the following CPU usage figures:
