13:59 <tolszak> Hello guys, anyone have an idea what to enable in yocto's meta-meson to get hdmi sound over pulseaudio. I've built amlogic-image-sato and there is no pulse audio card available

13:59 <tolszak> Only dummy sink

14:02 <narmstrong> tolszak: which board ? in meta-meson, only a few card have the correct audio routing setup as mixer configs

14:02 <tolszak> odroid n2 plus

14:03 <tolszak> I've tested kubuntu 21.10 which I suppose has more or less upstream kernel and audio works there

14:03 <narmstrong> here is how LibreELEC does audio setup https://github.com/LibreELEC/LibreELEC.tv/blob/master/packages/audio/alsa-utils/scripts/soundconfig#L131

14:03 <tolszak> kernel on kubuntu is 5.15

14:03 <narmstrong> they must have a script which does audio setup

14:04 <tolszak> Thank you! Will look at the script

14:04 <narmstrong> let me open another issu in GH about that...

14:05 <tolszak> so actually I need amixer to make it work instead of having pulseaudio plugin

14:05 <tolszak> narmstrong: Previously I used usb speakers and it worked pretty good

14:05 <tolszak> comparing to other soc's or even intel boards - less tweaks needed.

14:05 <tolszak> But I now realized that there is no hdmi output

14:07 <narmstrong> with proper amixer config it works well

14:09 <gbisson> \q chewitt

14:09 <gbisson> sorry ;)

14:11 <chewitt> driver routing comes from device-tree (so nothing to change) but userspace needs mixer settings our you get spam in dmesg

14:12 <tolszak> On kubuntu there is a file

14:12 <tolszak> narmstrong: /usr/share/alsa/cards/G12B-ODROID-N2.conf

14:12 <chewitt> it's simple to fix if you are creating images for a single board .. you can one-time save config using alsactl, then restore it on boot

14:13 <chewitt> it becomes more challenging once you attempt single images support for many boards

14:13 <chewitt> hence the soundconfig script that I use with LE

14:13 <tolszak> That's content: https://pastebin.com/iDhkVqFH

14:13 <chewitt> i've been trying to wrap my brain around alsa ucm2 with the long-term idea of upstreaming something that generally works

14:14 <tolszak> chewitt: At first glance the debian/ubuntu approach seems generic

14:14 <chewitt> that's the alsa conf

14:14 <chewitt> that gives you a detected device

14:14 <narmstrong> here you go https://github.com/tobetter/odroid-alsa/tree/master/usr/share/alsa/cards

14:14 <chewitt> but you still need to set mixer settings :)

14:15 <narmstrong> wait yes snother package is missing

14:16 <tolszak> That's content of /etc/alsa/conf.d

14:16 <tolszak> https://pastebin.com/j335JvkA

14:18 <tolszak> grepping for mixer in etc shows /etc/init.d/alsa-utils and modprobe.d/alsa-base.conf

14:19 <narmstrong> can't find the script... must be a first boot stuff in odroid-base but I can't find it

14:19 <narmstrong> HK source is a mess

14:20 <chewitt> HK restore a saved-state file using alsactl IIRC

14:21 <tolszak> narmstrong: That's init.d script which looks a bit similar to what you sent https://pastebin.com/VdDAxGks

14:22 <narmstrong> that's the default init script for alsactl store/restore

14:23 <narmstrong> all these should go in https://github.com/superna9999/meta-meson/tree/honister/recipes-bsp/alsa-state

14:24 <narmstrong> or a script or the new way introduced recently

14:27 <Guest59> Hello Everybody. I am looking for a way to minimize idle power consumption of the LePotato board. I was able to go down to 0.18A by shutting down all but 1 CPU core, powersave governor and using meson-gxl-s905x-libretech-cc-v2 dtb instead of meson-gxl-s905x-libretech-cc. I don't need USB or HDMI, only Ethernet. I would be greatful for any hints if

14:27 <Guest59> I can disable anything else to save some milliamps, e.g. is is possible to completely disable HDMI?

14:29 <tolszak> narmstrong: Found it, it is in /usr/share/odroid-alsa/functions

14:30 <tolszak> narmstrong: https://pastebin.com/jxceKF4Z

14:30 <narmstrong> @Guest59: yes you can modify the DT to disable the vpu code and usb controller entirety

14:31 <narmstrong> tolszak: this is the one

14:31 <tolszak> SO what I need is to ensure that I;ve installed amixer and just run this script on startup right?

14:33 <tolszak> #!/bin/sh

14:33 <tolszak> . /usr/share/odroid-alsa/functions

14:33 <tolszak> if [ ! -f /var/lib/alsa/asound.state ]; then

14:33 <tolszak> if dpkg -l | grep odroid-alsa >/dev/null; then

14:33 <tolszak> dpkg-reconfigure odroid-alsa

14:33 <tolszak> fi

14:33 <tolszak> fi

14:34 <tolszak> That's the firstboot script

14:36 <tolszak> narmstrong: And that's the postinst script od odroid-alsa package

14:36 <tolszak> #!/bin/sh

14:36 <tolszak> . /usr/share/odroid-alsa/functions

14:36 <tolszak> alsa_setup

14:36 <tolszak> if [ -f /etc/pulse/default.pa ]; then

14:36 <tolszak> sed -i "/set-card-profile/d" /etc/pulse/default.pa

14:36 <tolszak> echo "set-card-profile 0 output:hdmi-stereo" \

14:36 <tolszak> >> /etc/pulse/default.pa

14:36 <tolszak> fi

14:58 <tolszak> chewitt: I've just realized that it was you who replied on odroid forum about panfrost issue. Thanks!

15:03 <chewitt> I get around :)

15:04 <Guest59> narmstrong Thank you for the hints! What is the correct way do disable vpu? Removing it makes the board unbootable and there is no "status" property.

15:05 <narmstrong> @Guest59: just add the property in the node

15:07 <chewitt> normally setting "disabled" instead of "okay" in the root nodes

15:24 <Guest59> Thank you. It's down to 0.17A after disabling gpu and vpu. Disabling USB seems to make no difference when nothing is connected to it.

16:34 <gbisson> mkorpershoek: ok so I believe I found the reason for the bcb issue

16:34 <gbisson> mkorpershoek: it's a mem address issue, I can reproduce the all 0s buffer with mmc read

16:35 <gbisson> I didn't bisect as I don't have a vim3 board so painful

16:36 <gbisson> at least it's not cache related, the cache mechanism of mmc/blk is ok and works as expected

16:41 <gbisson> mkorpershoek: fixed!

16:41 <gbisson> mkorpershoek: pretty it wasn't bisectable actually, I'd say it's toolchain-specific

16:42 <gbisson> pretty sure*

16:42 <gbisson> mkorpershoek: I'll cc to my patch as it might not be accepted as-is

16:45 <mkorpershoek> gbisson: great news! thank you for having looked into it :)

18:00 <BiggestSmile> hey guys. new to all this kernel building stuff, but.. i have x96 box powered by s905x3 and i super wanna run more up-to-date distros like ubuntu 21 on it. is it feasible task?
