PA only register one A2DP sink and one A2DP source, so you can only connect to one headset at time. We could in theory not publish the in_use flag of endpoints, but afaik we tried that some years ago and that caused some problems, so perhaps adding more endpoints to PA would work. > Version-Release number of selected component (if applicable): > bluez-5.50-1.fc28.x86_64 > pulseaudio-12.2-1.fc28.x86_64 > > How reproducible: > Always. > > Case 1: > Steps to Reproduce: > 1. bluetoothctl > 2. connect 50:1A:A5:xx:xx:xx # Jabra Evolve 65 > 3. connect 00:02:3C:yy:yy:yy # Creative MUVO 2c > > Actual results: > Attempting to connect to 00:02:3C:yy:yy:yy > Failed to connect: org.bluez.Error.Failed > > Expected results: > Attempting to connect to 00:02:3C:yy:yy:yy > [CHG] Device 00:02:3C:yy:yy:yy Connected: yes > Connection successful > [CHG] Device 00:02:3C:yy:yy:yy ServicesResolved: yes > > Case 2: > Steps to Reproduce: > 1. bluetoothctl > 2. connect 00:02:3C:yy:yy:yy # Creative MUVO 2c > 3. connect 50:1A:A5:xx:xx:xx # Jabra Evolve 65 > 4. pactl set-card-profile bluez_card.50_1A_A5_xx_xx_xx a2dp_sink > 5. pactl list sinks short |grep bluez > > Actual results: > $ pactl set-card-profile bluez_card.50_1A_A5_xx_xx_xx a2dp_sink > Failure: Input/Output error > $ pactl list sinks short |grep bluez > 26 bluez_sink.00_02_3C_yy_yy_yy.a2dp_sink module-bluez5-device.c s16le 2ch 44100Hz SUSPENDED > 27 bluez_sink.50_1A_A5_xx_xx_xx.headset_head_unit module-bluez5-device.c s16le 1ch 8000Hz IDLE > > Expected results: > $ pactl set-card-profile bluez_card.50_1A_A5_xx_xx_xx a2dp_sink > $ pactl list sinks short |grep bluez > 26 bluez_sink.00_02_3C_yy_yy_yy.a2dp_sink module-bluez5-device.c s16le 2ch 44100Hz SUSPENDED > 27 bluez_sink.50_1A_A5_D7_43_93.a2dp_sink module-bluez5-device.c s16le 2ch 44100Hz SUSPENDED > > Additional info: > Selecting a2dp_sink when Jabra is the only device with a2dp_sink > connected works just fine. > > Regards, > Dominik > -- > Fedora https://getfedora.org | RPMFusion http://rpmfusion.org > There should be a science of discontent.
