Hello the list! Suddenly, earlier this week, my bluetooth headphones stopped working with Stretch. I update weekly, usually on Sundays, and I am not sure because I wasn't paying attention whether I had successfully used my headphones before the last update I did last Sunday. They definitely were working properly one week before that, when I used them with the computer just before going off on a week-long business trip. Anyway, I use Gnome. When I want to connect the headphones I turn them on, click on the network-like icon in the top right of the screen, click on "Not in Use" beside the Bluetooth icon, and then click on "Bluetooth Settings". (Is there a more efficient, involving fewer clicks, way to connect, by the way?) In Bluetooth Settings I can see my headphones as "BeoPlay H8". If I click on them it brings up the window with the slider switch to connect them. Normally, what would have happened is that clicking that switch would have connected the headphones. WHat happens now is the switch goes very briefly to the ON position, and then goes straight back to the OFF position. Removing / forgetting the device and re-pairing leads to the same result -- pairing is successful, but cannot connect. With journalctl -f running in a terminal while trying to connect I see the following at the moment of clicking the slider switch to connect the headphones: a2dp-sink profile connect failed for AA:BB:CC:DD:EE:FF: Protocol not available <bluetooth address elided, it is actually a sensible-looking bluetooth address> Now, call me a super-sleuth, but I suspect that Protocol Not Available error could be something to do with the problem ;) To re-iterate, this was working until recently, and all I've done is install regular updates using apt update / apt upgrade. Where should I start looking? [Full disclosure -- I previously had a different problem on upgrading to Stretch from Jessie -- see this link for that problem and a link to its solution --> https://lists.debian.org/debian-user/2017/06/msg01196.html I have never been particularly happy with the solution I linked to in that thread, precisely because I was worried it would be damaged by updates, but it seems to be intact at this point, so I don't think that is what the problem is here] Thanks in advance if anyone can help me diagnose the sudden loss of the a2dp-sink protocol. The headphones work fine with my iPhone, so the problem seems to be with the computer, with which they were working fine until a bit over a week ago. Mark
Pulseaudio? If so what does pavucontrol say Did Bluez updates come through? maybe pulseaudio-bluetooth module? regards...
