10:15 <hexdump> LiquidAcid: your 257px patch indeed fixed my x2 hdmi problem - with it get a proper 1280x1024 signal for my monitor - thx a lot!

10:35 <hexdump> is audio supposed to work out of the box on the x2 on mainline? i checked and i have set all the options you combined in your x2/u3 option, but don't get anything in /proc/asound/cards - are there other changes in the tree to make audio work, maybe in your dtb changes?

10:49 <mszyprow> hexdump: audio works on x2/u3 with mainline out of the box

10:50 <mszyprow> hexdump: I just test it with "aplay /usr/share/sounds/alsa/*.wav"

11:28 <hexdump> strange - for me there is no audio device - which kernel version and config is this on your end? (4.12.8 and exynos_defconfig with some docker required options)

11:38 <mszyprow> hexdump: vanilla v4.12 with exynos_defconfig

11:38 <mszyprow> hexdump: just tested to be sure, odroid u3

11:39 <mszyprow> [ 2.215920] max98090 1-0010: MAX98090 REVID=0x43

11:39 <mszyprow> [ 2.278797] max98090 1-0010: use default 2.8v micbias

11:39 <mszyprow> [ 2.359272] #0: Odroid-U3

11:39 <mszyprow> [ 2.357183] ALSA device list:

11:39 <mszyprow> [ 2.309550] asoc-simple-card sound: HiFi <-> 3830000.i2s mapping ok

11:42 <hexdump> ok - thx - will have to double-check

11:42 <hexdump> maybe its because i have changed the sound stuff to modules, but they get properly loaded

11:43 <mszyprow> hexdump: everything compiled in

11:43 <mszyprow> hexdump: maybe you missed some modules or so

11:43 <mszyprow> hexdump: or indeed there is an issue with modules

11:44 <mszyprow> hexdump: but I have no time now to check it with modules

11:45 <mszyprow> X2 also works fine, I just checked the eMMC used earlier in U3 in the X2 board

11:45 <hexdump> no problem - let me double check first - just built LiquidAcid's 4.13 kernel with the same config, lets see if i get audio there

11:48 <mszyprow> hexdump: better check vanilla exynos_defconfig first

12:03 <hexdump> will do

13:09 <hexdump> ok, with exynos_defconfig audio works - will have to check, which option in my config did break it

13:25 <tjakobi> hexdump, concerning the sound question, like marek said, it should work on mainline

13:26 <tjakobi> i have just added some kconfig to my tree to make things easier (https://github.com/tobiasjakobi/linux-odroid-public/commit/824133eca0d9abc46a44c6dfe5f22fa0a4c27b49)

13:26 <tjakobi> and because i always tend to forget what options need to be enabled

13:36 <hexdump> tjakobi: yes i saw your config option and had all thos in - mainline from exynos_defconfig really works - rebuilding my config now with sound no longer as modules, lets see if this changes things ... one other thing was different in my config too: i had usb-audio enabled as well

13:40 <tjakobi> would be interesting to know if it's related to build-in vs. module. i think i have never used the internal codec as module

14:12 <tjakobi> hexdump, i just sent the 275px hack to the ml. if you want, make some noise and voice your interest. might improve the chance for this to hit upstream

22:30 <hexdump> it looks like the reason for the missing alsa devices was the sound being compiled as modulues - i have now reverted all the module compile from m to y and now i have working sound with my config too

22:32 <hexdump> anoher sound question: still the sound does not work on the snow chromebook (5250) - /proc/asounc/cards looks good, alsamixer and all works, but i can't get sound ... the hardware seems to be the same as on the x2: max98090 codec, but looking into the dts files the sound stuff there looks completely different

22:33 <hexdump> would it be possible to rewrite the sound part of exynos5250-snow-*.dts* in a way like exynos-odroid*.dts*? i tried to have a look at it, but i do not really understand enough of how all this dtb stuff works

22:34 <hexdump> in last line i ment exynos4412-odroid*.dts*

22:35 <hexdump> one other thing i notice with mainline (4.12.8) on the x2 is that reboot does not work - but i think i saw patches for that in tjakobi's tree - will have a look at this in the next days

22:36 <hexdump> and will respond to the list tomorrow regarding the 257px patch

22:41 <hexdump> another nice side-effect of the 257px patch is that i can now properly connect the monitor to the hdmi port of the snow chromebook and it works perfectly and i can set everything fine with xrandr

22:41 <hexdump> i.e. external monitor work and extending the desktop to it as well

22:44 <hexdump> btw. i can really recommend those snow chomebooks (xe303c12), they are light (just about 1kg), quite cheap nowadays, everything works with a slef compiled chromeos kernel (3.8) and a lot works with mainline (no audio and no suspend at least) and its still quite snappy with its dated 1.7ghz dual-core

22:45 <hexdump> battery still lasts around 4-6 hours even on a used device - quite impressive keeping in mind that they are a few years ald now already

23:05 <Wizzup> hexdump: for sound on snow you need toggle certain switches

23:05 <Wizzup> but it will in the end still not work, because the sound runs too fast and is unstable

23:05 <Wizzup> suspend used to work fine in mainline

23:05 <Wizzup> audio never worked well on mainline, battery life can be up to 11 hours

23:06 <Wizzup> for example this is the only way to get 44.1Khz audio to play somewhat decently on snow/peach-pi: mpv --audio-pitch-correction=no --speed=0.91 foo.wav

23:06 <Wizzup> for 48000 you want 0.75 speed...

23:06 <Wizzup> and this of course doesn't work outside of mpv

23:06 <Wizzup> There's something wrong with the PLLs I think

23:07 <Wizzup> <-- been using peach pi as main work machine ever since I got it ... like two years ago?

23:08 <Wizzup> another thing that I'd like to fix is the brightness sensitivity. on chromeos kernel it was much more sensitive/nicer, in mainline it's very coarse

23:09 <Wizzup> but everything else works great

23:21 <hexdump> Wizzup: do you remember which switches one needs to toggle to get sound working at all? so far everything looks good, but ido not get any sound out of the speakers - ucm stuff should be correct and alsamixer setting as proper too i think

23:21 <Wizzup> Left Speaker Mixer Left DAC?

23:22 <Wizzup> those kinds of things

23:22 <Wizzup> Left Speaker Mixer Right DAC

23:22 <Wizzup> same for Right Speaker

23:22 <Wizzup> I'm going to sleep.

23:23 <hexdump> this i all have, but still no sound at all

23:24 <Wizzup> http://sprunge.us/SChb <- peach pi amixer

23:25 <Wizzup> on 4.11.12.
