<aka_[m]> are there any debugging switches in alsa for userspace?
<aka_[m]> Was loosing my mind over non enabled dai backend and it turned out i included not-exisiting file in UCM conf
<aka_[m]> aklimov: right from the bat it seems wcd937x driver misses LO/CLSH enable switch which should be toggled from ucm like its done on wcd938x
<aka_[m]> DS when enabling RX3 toggles LO, for RX1 it toggles HPHL and for RX2 HPHR
<aka_[m]> somehow while i got earpiece working speaker ain't wanting to work
<aka_[m]> no idea if there is channel miss-config or something
<aka_[m]> but ear is on left
<aka_[m]> ds when comparing tinymix otuputs from headphones and ear+bottom(thats default combo) only shows this control diff... (full message at <https://matrix.org/_matrix/media/v3/download/matrix.org/LmiXctAochMbGpZJtCfOKWDK>)
<aka_[m]> vs just one on headphone
<aka_[m]> no idea if in ucm i should mux RX1 into different Multimedia
<aka_[m]> or into same like RX0
<aka_[m]> tried once and it crashed on me

<aklimov> aka_[m]: no success here. I discussed that switch with Prasad on Friday and yes, it is missing
<aklimov> aka_[m]: EAR output from wcd is analog, right?
<aklimov> aka_[m]: wait, i didn't add CLSH switch
<aklimov> aka_[m]: on qrb4210 the AUX also should be "right" channel and non-existing EAR should "left" channel
<aka_[m]> aklimov: do you have working downstream?
<aka_[m]> What about dumping wcd regs from it?
<aka_[m]> After enabling stream
<aka_[m]> There is also thing about that wcd I don't like
<aka_[m]> It says it has 3 inputs and ds says it connects to hp/hr/aux but my schematics says inp3 comes from mic gnd
srinik has joined #linux-msm
<aka_[m]> And i sorta believe maybe rdac4 should have mux like rdac3 to route audio from either rx2 or rx1
<aka_[m]> or maybe there is minimal chance i need to have only 2 switches enabled to get CLSH?
<aka_[m]> schematic for my dumb phone:
<aka_[m]> HPH_REF <-HP_GND
<aka_[m]> hmm
<aka_[m]> what if AUX alone is bad
<aka_[m]> so with this it means we can mux into EAR_OUT either AUX(RX3) or HPHL(RX1)
<aka_[m]> can we mux into AUX_OUT something else than RX3?
<aka_[m]> time to go, hope you get some progress
<aka_[m]> im bit burned out on this.

<aklimov> aka_[m]: yes, i tested downstream and it worked there, but it had production kernel and not debuggable at all (no debugfs)
telent has quit []
<aklimov> aka_[m]: schematics link doesn't work for me
<aka_[m]> Guess some blocks you have
<aka_[m]> Can't you printk from wcd937x.c?
<aka_[m]> Unless ds kernel had no sauce
<aka_[m]> I'm too stupid to manage to o build my ds kernel as it fails to build with anything starting from old gcc to clang
<aka_[m]> And it some old 4.19.83 or something
telent has joined #linux-msm
<aka_[m]> I kinda hate lack of /dev/mem in android kernels otherwise I would just use iotools
