<div dir="ltr">Hi Julian, To debug pulseaudio please run: pulseaudio with -"vvvvv" parameter. To debug bluetooth please run bluetooth daemon: bluetoothd with "-d -n". Also you can get hci bluetooth logs with btmon. To get this data run simply with superuser btmon. This is useful to know what's happening "over air". Best regards, Grzegorz<code> </code></div><div class="gmail_extra"> <div class="gmail_quote">2017-07-19 22:34 GMT+02:00 Julian Sikorski <<a href="mailto:belegdol@gmail.com" target="_blank">belegdol@gmail.com</a>>: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi list, I have recently purchased a pair of bluetooth headphones. While A2DP support seems to be working fine, HSP/HFP are not. In A2DP mode I can do the speaker test in gnome-control-center without issues. On the other hand, switching to HSP/HFP mode using pavucontrol results in no sound being played and the bluetooth connection being dropped very quickly. A quick google search reveals that this seems to have been an ongoing issue until recently at least. Is it expected to work on pulseaudio 10? If so, how can I try do debug it?
