09:34 <marc|gonzalez> srinik: bamse: are you aware of any effort (even incomplete) to mainline sound/audio support for msm8998/apq8098 ?

10:15 <aka_[m]> marc|gonzalez: it shouldn't be much different to currently supported socs

10:16 <aka_[m]> What kind of codecs your device use?

10:16 <aka_[m]> On 660 it can use codec from pmi or wcd9335 for analog frontend

10:17 <phh> if i'm not mistaken that's "custom" (as in non-qualcomm) codecs over I2S for both input and output

10:17 <aka_[m]> Well

10:18 <aka_[m]> On older socs

10:18 <aka_[m]> Analog front-end is done via pm codec and digital front-end(connected to mi2s) is done via custom codecs like tas/tfa

10:19 <phh> (also the output is 3.3 but there is a custom adsp module that converts 5.1 to 3.3. let's say it's a problem for later)

10:42 <marc|gonzalez> aka_[m]: do you suggest to look at msm8996 or sdm660 or sdm845?

11:59 <phh> and there is HDMI (both output and input for ARC)

12:20 <marc|gonzalez> rawoul just mentioned that, as far as HDMI audio is concerned, sdm660 & sdm845 would be no help as qcom dropped support for that after 8998.

13:37 <aka_[m]> <marc|gonzalez> "aka_: do you suggest to look..." <- it all depends on specific board setup

13:38 <aka_[m]> 8996 tends to ship with wcd9335 connected over slimbus

13:38 <aka_[m]> cheaper socs like 8953 mostly use pm codec but also can use slimbus

13:38 <aka_[m]> if your device uses pm codec there is some work done on 660/670

13:38 <aka_[m]> not sure if it works tho

13:40 <aka_[m]> qcom,model = "msm8998-tavil-snd-card";... (full message at <https://matrix.org/_matrix/media/v3/download/matrix.org/YLGvRQkVEaowDSKuHMYLjUVO>)

13:40 <aka_[m]> tasha is wcd9335 setup

13:41 <marc|gonzalez> aka_[m]: our board doesn't use slimbus or wcd9335 or wsaXX :)

13:41 <aka_[m]> is there ds sauce for it?

13:42 <marc|gonzalez> ds sauce = DT source? :)

13:42 <aka_[m]> downstream source

13:42 <marc|gonzalez> Yeah it's in one of the qcom trees, lemme find a link

13:42 <aka_[m]> uh tavil seems to be not pm one but atleast have source
