I ran the following steps: 1. Power laptop on with bluetooth turned off 2. Turn BT on in gnome settings and set my BT headphones in pairing mode 3. Pair the headphones. 4. In Sound settings, it looks like the selected device is the BT headphones, but if I play something it outputs on the laptop speakers. output of `pactl list` gives something interesting though: Source #1 State: RUNNING Name: alsa_input.pci-0000_00_1f.3.analog-stereo Description: Built-in Audio Analog Stereo Driver: module-alsa-card.c Sample Specification: s16le 2ch 44100Hz Channel Map: front-left,front-right Owner Module: 7 Mute: no Volume: front-left: 30421 / 46% / -20.00 dB, front-right: 30421 / 46% / -20.00 dB balance 0.00 Base Volume: 6554 / 10% / -60.00 dB Monitor of Sink: n/a Latency: 123 usec, configured 40000 usec Flags: HARDWARE HW_MUTE_CTRL HW_VOLUME_CTRL DECIBEL_VOLUME LATENCY Properties: alsa.resolution_bits = "16" device.api = "alsa" device.class = "sound" alsa.class = "generic" alsa.subclass = "generic-mix" alsa.name = "ALC3254 Analog" alsa.id = "ALC3254 Analog" alsa.subdevice = "0" alsa.subdevice_name = "subdevice #0" alsa.device = "0" alsa.card = "0" alsa.card_name = "HDA Intel PCH" alsa.long_card_name = "HDA Intel PCH at 0xd1128000 irq 128" alsa.driver_name = "snd_hda_intel" device.bus_path = "pci-0000:00:1f.3" sysfs.path = "/devices/pci0000:00/0000:00:1f.3/sound/card0" device.bus = "pci" device.vendor.id = "8086" device.vendor.name = "Intel Corporation" device.product.id = "9d71" device.product.name = "Sunrise Point-LP HD Audio" device.form_factor = "internal" device.string = "front:0" device.buffering.buffer_size = "65536" device.buffering.fragment_size = "32768" device.access_mode = "mmap+timer" device.profile.name = "analog-stereo" device.profile.description = "Analog Stereo" device.description = "Built-in Audio Analog Stereo" alsa.mixer_name = "Realtek ALC3254" alsa.components = "HDA:10ec0295,102807e9,00100002 HDA:8086280b,80860101,00100000" module-udev-detect.discovered = "1" device.icon_name = "audio-card-pci" Ports: analog-input-internal-mic: Internal Microphone (priority: 8900) analog-input-headphone-mic: Microphone (priority: 8700, not available) analog-input-headset-mic: Headset Microphone (priority: 8800, not available) Active Port: analog-input-internal-mic Formats: pcm Source #2 State: SUSPENDED Name: bluez_sink.E3_28_E9_21_94_78.a2dp_sink.monitor Description: Monitor of TaoTronics TT-BH07 Driver: module-bluez5-device.c Sample Specification: s16le 2ch 44100Hz Channel Map: front-left,front-right Owner Module: 25 Mute: no Volume: front-left: 65536 / 100% / 0.00 dB, front-right: 65536 / 100% / 0.00 dB balance 0.00 Base Volume: 65536 / 100% / 0.00 dB Monitor of Sink: bluez_sink.E3_28_E9_21_94_78.a2dp_sink Latency: 0 usec, configured 0 usec Flags: DECIBEL_VOLUME LATENCY Properties: device.description = "Monitor of TaoTronics TT-BH07" device.class = "monitor" device.string = "E3:28:E9:21:94:78" device.api = "bluez" device.bus = "bluetooth" device.form_factor = "headset" bluez.path = "/org/bluez/hci0/dev_E3_28_E9_21_94_78" bluez.class = "0x240404" bluez.alias = "TaoTronics TT-BH07" device.icon_name = "audio-headset-bluetooth" device.intended_roles = "phone" Formats: pcm This matches what I have, but not what I see in Sound settings. 5. Now, if I select the speakers as the output device in the sound settings, then back to BT device, the sound is correctly output to the BT headphones (and not the laptop speakers), and I see this in `pactl list`: Source #1 State: RUNNING Name: alsa_input.pci-0000_00_1f.3.analog-stereo Description: Built-in Audio Analog Stereo Driver: module-alsa-card.c Sample Specification: s16le 2ch 44100Hz Channel Map: front-left,front-right Owner Module: 7 Mute: no Volume: front-left: 30421 / 46% / -20.00 dB, front-right: 30421 / 46% / -20.00 dB balance 0.00 Base Volume: 6554 / 10% / -60.00 dB Monitor of Sink: n/a Latency: 6610 usec, configured 40000 usec Flags: HARDWARE HW_MUTE_CTRL HW_VOLUME_CTRL DECIBEL_VOLUME LATENCY Properties: alsa.resolution_bits = "16" device.api = "alsa" device.class = "sound" alsa.class = "generic" alsa.subclass = "generic-mix" alsa.name = "ALC3254 Analog" alsa.id = "ALC3254 Analog" alsa.subdevice = "0" alsa.subdevice_name = "subdevice #0" alsa.device = "0" alsa.card = "0" alsa.card_name = "HDA Intel PCH" alsa.long_card_name = "HDA Intel PCH at 0xd1128000 irq 128" alsa.driver_name = "snd_hda_intel" device.bus_path = "pci-0000:00:1f.3" sysfs.path = "/devices/pci0000:00/0000:00:1f.3/sound/card0" device.bus = "pci" device.vendor.id = "8086" device.vendor.name = "Intel Corporation" device.product.id = "9d71" device.product.name = "Sunrise Point-LP HD Audio" device.form_factor = "internal" device.string = "front:0" device.buffering.buffer_size = "65536" device.buffering.fragment_size = "32768" device.access_mode = "mmap+timer" device.profile.name = "analog-stereo" device.profile.description = "Analog Stereo" device.description = "Built-in Audio Analog Stereo" alsa.mixer_name = "Realtek ALC3254" alsa.components = "HDA:10ec0295,102807e9,00100002 HDA:8086280b,80860101,00100000" module-udev-detect.discovered = "1" device.icon_name = "audio-card-pci" Ports: analog-input-internal-mic: Internal Microphone (priority: 8900) analog-input-headphone-mic: Microphone (priority: 8700, not available) analog-input-headset-mic: Headset Microphone (priority: 8800, not available) Active Port: analog-input-internal-mic Formats: pcm Source #2 State: IDLE Name: bluez_sink.E3_28_E9_21_94_78.a2dp_sink.monitor Description: Monitor of TaoTronics TT-BH07 Driver: module-bluez5-device.c Sample Specification: s16le 2ch 44100Hz Channel Map: front-left,front-right Owner Module: 25 Mute: no Volume: front-left: 65536 / 100% / 0.00 dB, front-right: 65536 / 100% / 0.00 dB balance 0.00 Base Volume: 65536 / 100% / 0.00 dB Monitor of Sink: bluez_sink.E3_28_E9_21_94_78.a2dp_sink Latency: 0 usec, configured 45317 usec Flags: DECIBEL_VOLUME LATENCY Properties: device.description = "Monitor of TaoTronics TT-BH07" device.class = "monitor" device.string = "E3:28:E9:21:94:78" device.api = "bluez" device.bus = "bluetooth" device.form_factor = "headset" bluez.path = "/org/bluez/hci0/dev_E3_28_E9_21_94_78" bluez.class = "0x240404" bluez.alias = "TaoTronics TT-BH07" device.icon_name = "audio-headset-bluetooth" device.intended_roles = "phone" Formats: pcm The Bluetooth source goes from SUSPENDED to IDLE. I'll attach both logs: one from step 4 (with the BT device shown as selected in Sound Settings Output Device even though the sound outputs to the laptop speakers) and one from step 5 (after switching Output Device back and forth in the Sound settings screen).
