Description Jim Downie 2018-05-04 11:49:44 UTC

Description of problem:

Laptop appears to connect to bluetooth speaker (Anker SoundCore 2). gnome-bluetooth and bluetoothctl both say there is an active connection, and the speaker appears in audio devices in gnome-settings, but the speaker does not play a confirmation sound upon connection, and no audio can be heard when the speaker is selected as the audio output. The speaker worked perfectly with F27 and also pairs fine with my phone.

Bluetooth/WiFi chip is an Intel Corporation Wireless 8265 / 8275

journalctl provides this output:

Version-Release number of selected component (if applicable):

bluetoothctl version 5.49
linux-firmware 20180402

How reproducible:

Always, either when pairing for the first time or when reconnecting to the speaker.

Steps to Reproduce:
1. Pair speaker with computer via gnome-bluetooth or bluetoothctl.
2. Once paired, play audio.
3.

Actual results:

Bluetooth speaker appears to be connected but no audio can be heard.

Expected results:

Bluetooth speaker should connect and be able to play audio.

Same issue here. happy to perform tests if asked.

Comment 2 Jim Downie 2018-05-13 18:45:43 UTC

I have been playing about with this a bit and it seems it might be an issue with PulseAudio. Running pacmd ls, I can get the PulseAudio index for the device:

    index: 1
	name: <bluez_card.08_EB_ED_99_58_41>
	driver: <module-bluez5-device.c>
	owner module: 25
	properties:
		device.description = "SoundCore 2"
		device.string = "08:EB:ED:99:58:41"
		device.api = "bluez"
		device.class = "sound"
		device.bus = "bluetooth"
		device.form_factor = "speaker"
		bluez.path = "/org/bluez/hci0/dev_08_EB_ED_99_58_41"
		bluez.class = "0x240414"
		bluez.alias = "SoundCore 2"
		device.icon_name = "audio-speakers-bluetooth"

Then running `pacmd set-card-profile 1 a2dp_sink` forces the device into a2dp_sink mode, after which I can play sound through the device quite happily. This seems to be stable through both disconnecting and forgetting the device and re-pairing, though I haven't tried it after rebooting yet.

This message is a reminder that Fedora 28 is nearing its end of life.
On 2019-May-28 Fedora will stop maintaining and issuing updates for
Fedora 28. It is Fedora's policy to close all bug reports from releases
that are no longer maintained. At that time this bug will be closed as
EOL if it remains open with a Fedora 'version' of '28'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 28 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 4 Ben Cotton 2019-05-28 20:13:34 UTC

Fedora 28 changed to end-of-life (EOL) status on 2019-05-28. Fedora 28 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
