[opensuse-factory] bluetooth audio performance
Hi there, I got a few bluetooth speakers that behave very well but not when the source is my laptop. I'm inclined to think there is either a power management issue or a degradation? of the bluetooth signal after several minutes (10-15). for which I need to go into the Control Panel, disable Bluetooth, set it back on and off it goes well. While misbehaving, the audio is cutting off and is pretty behind to my play/pause actions. Is there some performance tuning that could be done to fix this? Broadcom Corp. BCM20702 Bluetooth 4.0 [ThinkPad] I don't see much help with btusb vermagic: 3.11.10-7-desktop SMP preempt mod_unload modversions parm: ignore_dga:Ignore devices with id 08fd:0001 (bool) parm: ignore_csr:Ignore devices with id 0a12:0001 (bool) parm: ignore_sniffer:Ignore devices with id 0a12:0002 (bool) parm: disable_scofix:Disable fixup of wrong SCO buffer size (bool) parm: force_scofix:Force fixup of wrong SCO buffers size (bool) parm: reset:Send HCI reset command on initialization (bool) and bluetooth parm: disable_esco:Disable eSCO connection creation (bool) parm: disable_ertm:Disable enhanced retransmission mode (bool) parm: enable_hs:Enable High Speed support (bool) I wonder if anyone else is having a similar problem and if any of these were any good?

What 'Control Panel'? I'm using bluetoothctl, but after pairing the headset, I had no job for it anymore.

I just tried this and it works fine for me (listening to my google play music collection via chromium for 22 minutes right now)
Is there some performance tuning that could be done to fix this?

I don't think it is a kernel issue. What bluez and pulseaudio version are you using? bluez-5.15 pulseaudio-4.99 works well here. Can you use a different BT dongle for testing? This would rule out issues with your particular device (or, if you use an old dongle, rule out buetooth 4.0 specifics) -- Stefan Seyfried "For a successful technology, reality must take precedence over public relations, for nature cannot be fooled." -- Richard Feynman -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
