Created attachment 117444 [details] Pulseaudio log first time succes + 2nd time fail Hi, I'm currently integrating in Yocto pulseaudio 6.0 with bluez 5.28 and ofono 1.16 on a Nitrogen6x board (with dongle bluetooth Belkin). My purpose is to use the board as handsfree gateway: with a smartphone connected via bluetooth redirect the sound of a voicecall from the smartphone to the board output (HFP profile). I already got it work on my computer as I can hear the voicecall with the computer's speaker as output and use the integrated microphone as input. I'm using Pulseaudio launched as a user-instance with the backend ofono. I had strange behaviour testing it : After connecting my phone with bluetoothctl pulseaudio create an HF card and I got the same output as on my computer where HFP is working D: [pulseaudio] bluez5-util.c: oFono is running: yes D: [pulseaudio] backend-ofono.c: New HF card found: /card_4 D: [pulseaudio] backend-ofono.c: RemoteAddress: 40:A6:D9:6E:1B:73 D: [pulseaudio] backend-ofono.c: LocalAddress: 00:0A:3A:7A:3A:58 D: [pulseaudio] bluez5-util.c: Transport /card_4 state changed from disconnected to idle D: [pulseaudio] module-bluez5-discover.c: Loading module-bluez5-device path=/org/bluez/hci0/dev_40_A6_D9_6E_1B_73 I: [pulseaudio] module-card-restore.c: Restoring port latency offsets for card bluez_card.40_A6_D9_6E_1B_73. I: [pulseaudio] card.c: Created 1 "bluez_card.40_A6_D9_6E_1B_73" D: [pulseaudio] module-bluez5-device.c: Acquiring transport /card_4 E: [pulseaudio] backend-ofono.c: Deferred setup failed on fd -1: Transport endpoint is not connected I dial a number on my phone and it works well at the first try, the audio is routed to the output of the board.(see pulseaudio_log_success_HFP) Then, I hangup the call and make a second try, and the problems are coming : pulseaudio loops for few minutes : I: [alsa-sink-HiFi sgtl5000-0] module-loopback.c: Could not peek into queue D: [bluetooth] module-loopback.c: Requesting rewind due to end of underrun. and I also have this kind of messages with dmesg : Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 1536 Bluetooth: hci0 SCO packet for unknown connection handle 48 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 1536 Bluetooth: hci0 SCO packet for unknown connection handle 48 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 4864 Bluetooth: hci0 SCO packet for unknown connection handle 14 Bluetooth: hci0 SCO packet for unknown connection handle 61695 Bluetooth: hci0 SCO packet for unknown connection handle 65527 Bluetooth: hci0 SCO packet for unknown connection handle 0 Bluetooth: hci0 SCO packet for unknown connection handle 65520 Bluetooth: hci0 SCO packet for unknown connection handle 57392 Bluetooth: hci0 SCO packet for unknown connection handle 101 Bluetooth: hci0 SCO packet for unknown connection handle 63191 Bluetooth: hci0 SCO packet for unknown connection handle 641 Bluetooth: hci0 SCO packet for unknown connection handle 3566 Bluetooth: hci0 SCO packet for unknown connection handle 60418 Bluetooth: hci0 SCO packet for unknown connection handle 41479 Bluetooth: hci0 SCO packet for unknown connection handle 2516 Bluetooth: hci0 SCO packet for unknown connection handle 6178 Bluetooth: hci0 SCO packet for unknown connection handle 56309 Bluetooth: hci0 SCO packet for unknown connection handle 5636 Bluetooth: hci0 SCO packet for unknown connection handle 20508 Bluetooth: Unexpected continuation frame (len 0) Bluetooth: Unexpected continuation frame (len 0) Bluetooth: Unexpected continuation frame (len 0) No sound can be heard in that case.
