Hi, I'm trying to enable HFP on pulseaudio 6.0 using oFono and bluez 5 on a new embedded platform which doesn't support alsa yet. In order to confirm that audio is 'played' I record it using parecord tool. - This method worked just fine when enabled a2dp a short time ago. After executing oFono & pulseaudio, a call is answered on the remote device- It is seemed that the relevant profile is chosen on pulseaudio, and parecord fails to record. When executing 'pacmd stat' it seems that Memory blocks allocated during the whole lifetime: 192, size: 699.9 KiB. Is constant while pulseaudio prints to terminal the following message along the call with relatively fixed intervals: ( 482.106| 0.013) D: [pulseaudio][modules/module-loopback.c:201 adjust_rates()] Should buffer 96 bytes, buffered at minimum 128 bytes ( 482.118| 0.012) D: [pulseaudio][modules/module-loopback.c:226 adjust_rates()] [bluez_sink.98_D6_F7_34_98_E8] Updated sampling rate to 8000 Hz.

Also, could someone explain why are there two source available? Nexus 4 and Nexus 4 monitor? How can I confirm that the audio arrives at pulseaudio? By the log I would assume that the answer is positive, but according to 'pacmd stat' the value it seems not. Thanks for your help, Eytan. -------------- next part -------------- An HTML attachment was scrubbed...
