Hi PulseAudio team,
Hope you are having a good day.
I’m trying to connect my Raspberry Pi 4 and mobile phone via Bluetooth to
access both media audio and phone call audio (A2DP and HFP), with the goal
of streaming this audio using GStreamer.
I successfully connected my Raspberry Pi to my phone and managed to get
both HFP and A2DP profiles. Running pacmd list-cards gave the following
output:
index: 5
> name: <bluez_card.2C_BE_EB_8B_F2_D7>
> driver: <module-bluez5-device.c>
> owner module: 39

> device.form_factor = "phone"
> bluez.path = "/org/bluez/hci1/dev_2C_BE_EB_8B_F2_D7"

> melphone
> ports:
> phone-output: Phone (priority 0, latency offset 0 usec,
> available: unknown)
> phone-input: Phone (priority 0, latency offset 0 usec,
> available: unknown)
To test audio streaming, I used the following GStreamer command:
> gst-launch-1.0 -v pulsesrc
> device=bluez_source.2C_BE_EB_8B_F2_D7.headset_audio_gateway ! audioconvert
> ! audioresample ! wavenc ! filesink location=output.wav
However, I encountered an issue: the media doesn’t play. The Video is not
paused, but playback doesn’t progress beyond 0:00.
Any guidance on resolving this would be greatly appreciated!
I am happy to provide any more info required.
Best regards,
Dhruv Menon
