03:13 <bamse> Marijn[m]: a coccinelle thing seems quite useful for that

09:09 <srinik> DylanVanAssche: sound should work all the time, I see no reason why it should not work. What kind of errors do you see in failure case?. Not to mention there are some pending slimbus patches that needs to be worked on w.r.t tearing the channels when playback/capture is done.

10:32 <DylanVanAssche> srinik: it happens when the routing is configured. So you execute the amixer cmds, play sound for the first time with aplay (no sound). Repeat aplay and it works fine since then

10:33 <DylanVanAssche> Maybe something is not fully initialized which is then achieved by the first time you run aplay?

10:33 <srinik> DylanVanAssche: or the sequence or the volume setting. do you see any errors when you do not hear

10:34 <DylanVanAssche> srinik: some underflow/overflow errors in the dmesg, but they happen as well when it works

10:34 <DylanVanAssche> DEBUG logs are enabled though

10:35 <srinik> DylanVanAssche: that is okay, it just happens due to the sequence of closing the slim ports and the channels

10:36 <srinik> DylanVanAssche: what ever you are seeing is not normal, I never noticed anything like that, it worth a debug this.. am guessing its to do with order of mixers

10:37 <DylanVanAssche> Besides those none, I checked it line-by-line. I just find it weird that it works after the second call to aplay. It only happens with the wcd codec btw

10:37 <srinik> DylanVanAssche: which kernel version are you using?

10:37 <DylanVanAssche> srinik: I will try to convert to your MR regarding the wcd codec to see if it improves. I use 5.18.1

14:25 <steev> srinik: speaking of pending patches - https://patchwork.kernel.org/project/alsa-devel/patch/20211210114747.1485-1-srinivas.kandagatla@linaro.org/ what happened with this? it's marked as both new and archived?

14:26 <steev> there are no responses at all to it though

14:28 <steev> https://git.linaro.org/people/srinivas.kandagatla/linux.git/commit/?h=c630/v5.15 this one also seems to not have gone anywhere?

14:37 <srinik> steev: will recheck and resend if required

14:38 <srinik> steev:i think the channels sorting thing might not be required, I need to verify this once again.

14:45 <steev> audio does seem to work without it on the c630

14:45 <steev> i'm just going through what patches i am applying to 5.19 and seeing what is still outstanding, and those two are two of them

14:53 <Tooniis[m]> srinik: is there a specific reason for using RX5/6 channels for headphones in db820c? https://github.com/alsa-project/alsa-ucm-conf/blob/master/ucm2/Qualcomm/apq8096/HiFi.conf#L12-L13

14:54 <Tooniis[m]> do the slimbus channels have different capabilities?

18:28 <vknecht[m]> any thought how to diagnose/fix such "rcu_preempt detected stalls" ? afaik it happens about when gpu/dsi/mdp should kick in... https://pastebin.com/aBnMYazg
