Follow up: I rebooted and I was able to make and hang up 5 calls in a row. All the audio was redirected correctly. I had some of the "SCO packet" errors.

Then, moments after hanging up the last call I got a kernel crash. I changed my screen display to be able to show the whole crash, so now I am able to see if in completion. I've attached it here. It's not very helpful. However, "swapper" is the same task that my other crashes were claiming, but I was doing post-mortem analysis on that other system (using 'crash') Inline image 1 On Sun, Sep 20, 2015 at 2:17 PM, Jason Gauthier <jagauthier(a)gmail.com <mailto:jagauthier@gmail.com>> wrote: Georg, Thanks for your response. I've never heard of that option before, so I added it. Up until this point, I've been just trying to figure it out. I've not found any documentation on how to accomplish this. So, I added that parameter. My results are similiar to results I've achieved before. No crashing this time. (But it's not 100% reliable either). I placed one call, and everything worked (audio in out of the computer). I've been able to get this to happen once in a while. I disconnect the call from the phone. I placed a second call, there wasn't any audio, and my logs scroll like this: [ 1052.809382] Bluetooth: hci0 SCO packet for unknown connection handle 2 [ 1052.809964] Bluetooth: hci0 SCO packet for unknown connection handle 16384 [ 1052.810563] Bluetooth: hci0 SCO packet for unknown connection handle 48 [ 1052.811371] Bluetooth: hci0 SCO packet for unknown connection handle 1 [ 1052.811982] Bluetooth: hci0 SCO packet for unknown connection handle 256 [ 1052.812581] Bluetooth: hci0 SCO packet for unknown connection handle 1 [ 1052.813378] Bluetooth: hci0 SCO packet for unknown connection handle 1 [ 1052.813968] Bluetooth: hci0 SCO packet for unknown connection handle 1 [ 1052.814712] Bluetooth: hci0 SCO packet for unknown connection handle 1 [ 1052.815681] Bluetooth: hci0 SCO packet for unknown connection handle 1 [ 1052.816536] Bluetooth: hci0 SCO packet for unknown connection handle 1 [ 1052.817712] Bluetooth: hci0 SCO packet for unknown connection handle 1 [ 1052.818544] Bluetooth: hci0 SCO packet for unknown connection handle 1 [ 1052.819508] Bluetooth: hci0 SCO packet for unknown connection handle 1 [ 1052.820332] Bluetooth: hci0 SCO packet for unknown connection handle 1 I disconnected that call. I placed a third call and all audio came out of the phone. In a few previous tests, when this happens I see that ofono still thinks I have a voicecall. So, I probed dbus to verify this: qdbus --system org.ofono As soon as I did that, the VM shut off. (No kernel crash - just instant off - I've seen this a few times) On Sat, Sep 19, 2015 at 9:59 AM, Georg Chini <georg(a)chini.tk <mailto:georg@chini.tk>> wrote: On 18.09.2015 20:01, Jason Gauthier wrote: Greetings, I've been working on getting a HFP working with bluez and pulseaudio.

Maybe >the virtualization layer is the reason for the kernel crashes. Did you also >test it on a physical machine? You are correct. I do a bunch of my R&D on a VM because the hardware is so much faster than the pi.. and I try not to compile over and over on the pi. So, I went through the set up this on my pi, to verify functionality. It really does work much better. As far as stability and functionality I would say it works like it should. After the first call, the audio is broken and distorted. the A2DP profile still plays perfectly though. I don't know which layer this is happening it. I restarted pulse, ofono, and bluetoothd methodically testing after each and could not improve it. So, that could at any layer. Thanks for your help. I've been struggling with this setup for a few weeks, trying to get it all to work.
