On a quick side note, to my knowledge pulseaudio is never up at boot. This is intentional as it helps speed up the boot time. PulseAudio should however be launched when requested, I think there is an issue with it not being started for phone related tasks ATM.
From: IVI [mailto:[email protected]] On Behalf Of Podolyak, Zoltan Sent: Wednesday, May 14, 2014 9:16 AM To: [email protected] Subject: Fwd: ofono/pulseaudio/bluez5 Hello Jaska, Thanks for your reply. I will try to be a bit more specific about what my problem is. I'm using the Plantronics_Plantronics_C420 USB headset with microphone. I'm aware that there's no pre-amp on the NDiS. It actually took me quite a while to just get the system to use the headset for our Music Player app. What I ended up doing is setting these settings in my /etc/pulse/client.conf file. default-sink = alsa_output.usb-Plantronics_Plantronics_C420-00-C420.analog-stereo default-source = alsa_input.usb-Plantronics_Plantronics_C420-00-C420.analog-mono With this setting, our Music Player uses the USB headset. I also verified the microphone with alsa tools such as aplay/arecord. This works fine. I'm definitely using default.pa<http://default.pa> when loading through the service file. Here's what it looks like: [Unit] Description=pulseaudio sound server [Service] ExecStart=/usr/bin/su app -c "DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/5000/dbus/user_bus_socket /usr/bin/pulseaudio --start --log-target=syslog" Restart=always [Install] WantedBy=multi-user.target So it's being loaded exactly how it would be loaded by webkit. My problem is, that when trying to make a call through my Bluetooth paired device, the audio still defaults to the built-in analog device. I verified this by connecting a regular headphone to the audio line-in jack. I do however, hear static on the USB headphone since that's loaded by default through my client.conf. My guess is that Bluetooth uses different PA settings or something because udev is detecting the audio drivers at PA startup. Here's the top part of the output from the pacmd list-modules command: index: 0 name: <module-udev-detect> argument: <> used: -1 load once: yes properties: module.author = "Lennart Poettering" module.description = "Detect available audio hardware and load matching drivers" module.version = "4.0-rebootstrapped" index: 1 name: <module-alsa-card> argument: <device_id="1" name="pci-0000_00_1b.0" card_name="alsa_card.pci-0000_00_1b.0" namereg_fail=false tsched=yes fixed_latency_range=no ignore_dB=no deferred_volume=yes use_ucm=yes card_properties="module-udev-detect.discovered=1"> used: 0 load once: no properties: module.author = "Lennart Poettering" module.description = "ALSA Card" module.version = "4.0-rebootstrapped" index: 2 name: <module-alsa-card> argument: <device_id="0" name="usb-Plantronics_Plantronics_C420-00-C420" card_name="alsa_card.usb-Plantronics_Plantronics_C420-00-C420" namereg_fail=false tsched=yes fixed_latency_range=no ignore_dB=no deferred_volume=yes use_ucm=yes card_properties="module-udev-detect.discovered=1"> used: 0 load once: no properties: module.author = "Lennart Poettering" module.description = "ALSA Card" module.version = "4.0-rebootstrapped" index: 3 name: <module-bluez5-discover> argument: <> used: -1 load once: yes properties: module.author = "João Paulo Rechi Vita" module.description = "Detect available BlueZ 5 Bluetooth audio devices and load BlueZ 5 Bluetooth audio drivers" module.version = "4.0-rebootstrapped" I'm going to try setting the default-sink/source to the USB headset from default.pa<http://default.pa> and see what happens. I also tried commenting out the udev detection, but the results were the same. The other strange thing is that I had this working through the USB headset on Friday. I played around with dLeyna a little bit and ever since then, BT only wants to use the built-in audio. I don't get it. Thanks for your help!

I had also little bit trouble figuring out what you are really trying to do. First, you should check, that despite your own .service files you are loading pulseaudio with the default.pa<http://default.pa> configuration file. This you can easily check by seeing if pulseaudio-module-murphy-ivi (policy/routing) module is loaded (pactl list modules). Otherwise you might be missing some automatic routing stuff... and then I can't help you too much :) Second, what kind of headset you are trying to connect (wired with separate mic and headphones, some phone headset with combined jack, usb, bluetooth)? As I remember ndis166 has only line in, so no microphone pre-amplifier. So with wired headset either you should use external preamp or shout like a mad man to hear anything (the levels are _really_ low). Also it might be that in ndis166 alsa is not even reporting "mic" to exist, so we are not routing there ever. Some phone headset with combined jack will just not work at all (the mic part). Could you try connecting usb headset? That's probably the easiest input/output device for testing the phone functionality. br, Jaska ________________________________________ From: IVI [[email protected]<mailto:[email protected]>] on behalf of Podolyak, Zoltan [[email protected]<mailto:[email protected]>] Sent: Tuesday, May 13, 2014 9:25 PM To: [email protected]<mailto:[email protected]> Subject: ofono/pulseaudio/bluez5 Hello Everyone, I've been playing around with ofono/pulseaudio/bluez5 recently, trying to get audio working over Bluetooth through our HTML5 Phone app. I noticed that pulseaudio is currently not started by default so I created a systemctl service file to start it up at boot time. My understanding is that currently GStreamer starts it somehow through webkit. I'm not sure if there's a better solution out there, such as launching it through ofono or something. Anyway, the problem I'm having is that even though I hard coded the default sink/sources in PA to use the headset (I verified this works by launching the Music Player app), Bluetooth audio is always routed through the on-board sound card. I'm using an NDiS 166 and this has no on-board microphone that we can use for testing. I know it's possible to route it through the headset because I had it working with some phones last week. However, after playing with DLNA and other audio stuff, it seems to be forever stuck on the on-board audio. I tried deleting PA settings files and the like, to no avail. Does anyone know where the sound source/sink is saved for BT? I'm using the newest versions of ofono/pulseaudio. Thanks!
