08:49 <DylanVanAssche> bamse: FYI: the HFP/HSP advertisement issue for the WCN3990 was due the fact that RFCOMM was built as builtin, it has to be a module otherwise the kernel won't initialize the RFCOMM layer, thus no HFP/HSP. This is a known thing according to the Gentoo wiki and I encountered it in the past as well but my patch was lost during rebase

09:13 <nergzd723> sounds like a bug

10:47 <DylanVanAssche> nergzd723: Yeah it is weird... but it is even documented on the Gentoo wiki so it is something that exists for a really long time already...

15:33 <bamse> DylanVanAssche: never knew, i always build non-essentials as modules...that certainly sounds like a bug to me

15:34 <bamse> DylanVanAssche: nice that it's documented, preferrably though it should have been fixed, or at least prevented

15:56 <DylanVanAssche> bamse: Yeah I have no clue why to be honest or I would have made a patch 😛 Anyway, I reached now the state where HFP is supported and connected devices actually switch between A2DP and HFP.

15:57 <DylanVanAssche> bamse: No audio though, 2 options: either PCM or over the serial HCI connection. No idea what the default is or what the HCI command is to switch (vendor specific)

20:57 <bamse> DylanVanAssche: when i flipped the mode in pavucontrol my ear drums broke...so i guess you should be lucky ;)

20:57 <bamse> DylanVanAssche: didn't know you potentially can switch between external and in-band audio, perhaps though srinik can give you some pointer on how to wire up the audio routing

21:22 <DylanVanAssche> bamse: heheh yes because in USB dongles it is always over HCI instead of PCM but the hard thing is finding the right raw HCI command

21:23 <DylanVanAssche> I found already some SLIMBus stuff in downstream for HFP. 7 and 8 are reserved for that and handled separately. If I am stuck I will ask :)
