Linux/AM4378: Bluetooth audio data not playing

Humm.. I thought, you got the HFP demo working, as per this thread. Is this different?

Thanks

I thought it was working, and everything besides the audio data is working. I can start a call, end a call, enter DTMF, etc. but there is no audio data. The audio data is not triggering the HFRM_Event_Callback() function.

From what I've been able to find online, it seems like it could be an issue with pulseaudio? Apparently pulseaudio is needed for Bluetooth audio to work? Is that correct, and if so how can I run pulseaudio? Whenever I try to run it I get the error:

W: [pulseaudio] main.c: This program is not intended to be run as root (unless --system is specified).
E: [pulseaudio] main.c: Daemon startup failed.

And when I try to run it with the --system flag, I get the following error:

W: [pulseaudio] main.c: Running in system mode, but --disallow-exit not set.
W: [pulseaudio] main.c: Running in system mode, but --disallow-module-loading not set.
N: [pulseaudio] main.c: Running in system mode, forcibly disabling SHM mode.
N: [pulseaudio] main.c: Running in system mode, forcibly disabling exit idle time.
W: [pulseaudio] main.c: OK, so you are running PA in system mode. Please note that you most likely shouldn't be doing that.
W: [pulseaudio] main.c: If you do it nonetheless then it's your own fault if things don't work as expected.
W: [pulseaudio] main.c: Please read www.freedesktop.org/.../ for an explanation why system mode is usually a bad idea.

Humm.. I do not think pulse audio is needed.. I believe, all that is needed is ALSA..

As, i noted earlier we have not tried the ALSA routing patches in a while with recent kernels. I will try to make build and test it on AM43x EVM and get back to you soon..

Thanks

Okay thank you

Any updates?

Not yet.. I have some AM43x setup issues, trying to resolve them.. Will get back in a day or two..

Thanks

We, are still working on this issue.. As, you noted with our patch builds on top of TISDK5.1 kernel, we hear no voice, even though from the WL18xx BT controller point of view every thing looks fine.. As, I said earlier we are not testing these assisted modes with each TISDK release and so not sure when it got broken.. I tried both the AG and HF modes and both failed with no voice.. We, took some BT snoop logs as well to check the RFCOMM, SDP interactions before the audio connection and they all seem fine..
We, will now probe the PCM connections between the AM437x and the COM8, to check further.. We, will keep you posted as we identify the issue and the resolution..

Thanks

Okay, yes just keep me posted. Thank you for the update.

Just to give you an update - We, have now verified the voice from peer (phone) to the AM437x Bt PCM and routed to AM437x AIC speakers working.. We, will now check in the other direction and provide you the patches..

Thanks

Hey Hari,

Just checking in, do you have an idea of when the patches will be available?

Sorry for the delay... I shared the files, please give it a try... We, will clean the patches with more comments etc and upload to our server soon..

Thanks

Please, let us know if the patches worked Ok..

Thanks

Yes, I will let you know. It might be a little bit before I get to try them out because we just got our custom boards, so I am currently working on getting that up and running. But once I get a chance (hopefully I will have time this week) I will try the patches out and let you know if they work.
