<steev>
heh
<steev>
one of the suggested things to do from pipewire devs was "upgrade alsa-firmware" so... that's a bust
<bamse>
steev: have you tried rebooting? ;)
<steev>
heh
<bamse>
at least in Europe we could try switching polarity of the ac cable...
<bamse>
well, in Sweden...several European countries that doesn't support flipping polarity of the power cable
<steev>
they also said try playing with the volume in alsamixer, but tbh, i really don't wanna re-find all that
<steev>
i don't understand why there are like 300 options exposed in there
<bamse>
steev: that's a question i've asked myself many times...
<bamse>
vkoul probably knows
<steev>
i remember something about rx7
<steev>
i'm too lazy to scroll back
<steev>
but again, scrolling through the 100+ options to find them.... zzzzzzzz
<bamse>
guess how i found that ;P
<steev>
you asked vkoul :P
<bamse>
i neighbors must have been happy as i sat there on my patio trying to lower the volume of my music
<steev>
lol
<bamse>
haha, no i couldn't wait for vkoul
<bamse>
had to find the knob :)
<bamse>
but is your pulsewire issue only related to the volume control?
<steev>
well
<steev>
it also pops when using aplay?
<bamse>
constantly?
<steev>
no
<steev>
it's just 2 pops at the very beginning, silence, and then *sometimes* 2 pops at the end
<bamse>
obviously you shouldn't have kfree'ed that buffer...
<steev>
i did "while true; do aplay -D hw:0,1 africa-toto.wav; done" and then in another terminal... i started futzing around with all the different alsamixer settings
<steev>
i want to say it was slimbus_0_*something* that it was unhappy that i muted
<bamse>
sounds like a bug in itself
iivanov has quit [Remote host closed the connection]
<steev>
https://bpa.st/QRTQ and another one but... i think i should stop fucking around with this because now i get absolutely nothing
<bamse>
steev: looks like it would be useful to put a fuzzer to work on the audio interface :)
<bamse>
steev: but for the sake of getting audio working, it doesn't look like you're moving in the right direction
<steev>
well, no
<steev>
so what i did was
<steev>
rm /var/lib/alsa
<steev>
reboot
<steev>
make sure var/lib/alsa was empty
<steev>
reboot again
<steev>
get blue screen, so reboot again
<steev>
this time, when it booted, i got the double pop, so audio is "back" and i can aplay the song
<steev>
i noticed something though
<steev>
i changed the ucm config to point to rx7 and.... that isn't completely right either
<steev>
because increasing and lowering the volume causes the mono audio to become stereo?
<bamse>
isn't that just one of the channels?
<steev>
well, yes, but i don't know how to say use 2 channels
<steev>
and i'm scared of alsamixer at this point
<bamse>
because that was the part that i think srini ran into, that they required him to somehow describe both channels
<bamse>
but that was a bleeding edge feature and didn't work for him
<steev>
i just think it's kinda cool that i can make mono stereo?
<bamse>
i wish i knew how to read those knobs
<bamse>
will have to bother vkoul or srini about it some more, maybe they can teach us
<steev>
hm
<steev>
yeah it's a bit more involved than just being rx7
<bamse>
i'm fine with it being rx7...but i would like to know what that actually is
<steev>
well what i mean is
<steev>
i have the volume all the way down... and it's still playing
<bamse>
not because one of the other rx is non-zero?
<bamse>
iirc rx7 was just one of the speakers
<steev>
i honestly have no idea... like i said i'm scared to go into alsamixer :P
<steev>
i gotta go find it
<steev>
which is the other annoying thing
<bamse>
which makes me wonder why this things worked prior to the refactoring...when i think we just did volume on rx2
<steev>
i really wish i could just / and RX7 and it would bring up all the rx7
<bamse>
i guess that's not very useful when you have the typical 2 bars in alsamixer ;)
<steev>
hm
<steev>
i can't find the second rx7 now?
<steev>
there is a "SpkrLeft PA" and "SpkrRight PA" and those seem to do the speaker volumes for... well, obviously, left and right
<steev>
i recall my x1c looked a lot like this when you went into the actual audio card
<steev>
it's definitely not arm specific anymore :(
<bamse>
there's two wsa8815 (iirc) that are dedicated amplifiers for the two speakers...but i don't know if they are just providing a constant amplification and that it's the input to those that are volume controlled
<bamse>
they should be in the list as well though...as least for muting purpose
<bamse>
or perhaps they are just powered on/off when needed
