Hallo all, (Pulseaudio and Bluetooth devs)
i have Samsung HS3000 bluetooth headset. Mostly it works but there are
different issue with it:
- volume level seems to be set to max (at really uncomfortable level)
- at the moment i trying to change volume with pavucontrol or after it i
get bad sound. Some times sort of cracky or trashy sound, some times
just white noise.
- play/stop key do not works with linux (not pulse issue)
how to troubleshoot this issues? what tools should i use and where
should it start?
Regarding the broken audio: I would suspect that the headset is buggy,
hehe, nice try :) This headset works perfectly with my
smartphone/cyanogenmod.
because the volume handling code should be pretty well tested in
pulseaudio, and I don't think bluetoothd touches the audio signal at
all. To confirm that, I think it's somehow possible to capture the audio
that is sent to the headset, but I don't know how. Maybe the bluez
people can answer that (I'm a pulseaudio guy myself).
Are you using the headset in the HSP or A2DP mode, btw? If A2DP, then
that would suggest a pulseaudio bug, since I don't think the headset
will get any notification via A2DP when you change the volume in
pavucontrol.
You right, i played with different profiles. HSP controls volume on
pulse, but minimal volume is still too loud. A2DP use internal volume
control and i can set it as silent as i need.
I made some more tests with different kernels. It looks more like kernel
issue. I get different oopses and it looks like 3.5.0 sounds better then
current master git.
