Call audio is not routed to headset with HFP

[Simon Fels]

With bluez 5.33 on Nexus 4 and silo 43 installed:

* pair and connect a headset over HFP
* Establish an outgoing call or accept an incoming one
* Once the call is established the call audio isn't routed through the handsfree device

[Simon Fels (morphis)]

There seems to something wrong with the whole management of audio over bluetooth between bluez <-> pulseaudio <-> media-hub as also switching between speakers and A2DP speaker doesn't work reliable and causes media playback to be not usable as long as a A2DP speaker is connected in some cases.

This is fixed now and working with silo 43 and 52.

[Pat McGowan (pat-mcgowan)]

still broken as described

[Simon Fels (morphis)]

@Pat: With which device you see this still broken? For my two headsets this working fine now. As I were the initial reporter I would like to close this as we have other bugs with the same symptoms and this is then just a duplicate.

[Konrad Zapałowicz (kzapalowicz)]

I confirm this with krillin running rc-proposed from 27th of Feb with silo 47 [pulseaudio fix].

During the call audio in not in the headset however it is possible to transfer it between the phone [works ok] and back through the Bluetooth [silence]. Will capture and attach logs later today.

Think this affects me too on my MX4 using HTC BH M200 headset. If there's anything I can send from the phone that'll help, let me know.
Looks by the packages that are affected that it could also be loosely related to https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1544477
This started with me with OTA-9 and continues after OTA-9.1

Status changed to 'Confirmed' because the bug affects multiple users.

@Geoff,

You could capture logs as stated here: https://wiki.ubuntu.com/DebuggingBluetooth

Thanks

@simon I have a rockfish mab2
I added logs at bug #1536493 which you attributed to pulse or telepathy-ofnono

[Geoff Lowther (r-ubuntuone-b)]

sorry not been able to set my phone up for logging at the moment - although reasonably technical and used to using the cli for out of the normal occasions, I don't go for the cli normally and prefer a gui, so just need to get my head around setting up.

Not sure if it helps, but I did notice though that for normal operation as long as you are slow in connecting everything then it does all seem to hang together. Here's what I do (to get it to work);
- have bluetooth switched on on the phone (with the pairing already completed)
- switch on the headset and wait for the bluetooth icon to go from a black background, to white and then back to black.
- wait 20-30 seconds (till I think it will have sorted itself out)
- press the button on the headset (the one that initiates a connection and is also used for answering and ending calls)
- wait till the bluetooth icon goes white and the bluetooth volume 'overlay' is shown - this can take 30-40 seconds

I can now make or receive calls and the sound/mic are passed to/from the headset correctly.

If I try to 'rush' this cycle or answer a call then switch on the headset, that's when the problem shows and I get connection to the headset to no sound to or from the headset or speakers/phone mic.

Looked through Pat's log file and it actually shows that the HFP profile is never correctly connected due to

Mar 1 13:26:27 ubuntu-phablet bluetoothd[739]: src/profile.c:ext_connect() hfp_ag connected to 00:18:16:20:00:FE
Mar 1 13:26:27 ubuntu-phablet bluetoothd[739]: src/service.c:change_state() 0xb775f8b8: device 00:18:16:20:00:FE profile hfp_ag state changed: connecting -> disconnected (-5)
Mar 1 13:26:27 ubuntu-phablet bluetoothd[739]: src/device.c:device_profile_connected() hfp_ag Input/output error (5)

That is the reason why audio is never routed throught he headset. Needs more investigation to find out what the reason for this is.

Really important feature very useful to get safer while driving / calling, marked as Critical is delayed; that's really sad :(
Is there anything that I can do help solving that bug? Provide some logs, test something?

[Peter Penzes (penzi-hu)]

I have N-Com BT3 headset and Nexus 4 r498.

[John McAleely (john.mcaleely)]

Is this the bug I saw last week? bug #1607466

[Peter Penzes (penzi-hu)]

@John

I think, yes. N-Com BT3 is mono headset.
Other car bt set work properly.

I have a Nokia J Bluetooth headset (BH-806) that connects to my Meizu Pro 5 Ubuntu phone OTA-13 but no sound is directed to the headset during calls or during music playing.

[David Kaplan (davidkiryat8)]

I have a CarKit bluetooth FM radio hands free kit that my Nexus4 running BQ Aquarius RC v69 can connect and does not crash but no sound is routed to the FM radio upon answering a call. The FM radio plays music from a disk on key until the call is answered where it goes silent. There is no sound coming from the phone's ear peice or speaker.

 My car has also a hands free generic Bluetooth kit recognized by touch as comf_comp V12b which connects and works but upon reconnection it crashes touch Bug #1579025 .

 Now I have two bluetooth devices that both do not work.
A working Hands free is a must to use touch when driving.
This is the reason for me dual booting Android.
 If there is anything I can do to help just respond.
 Thanks
