| | Do you have another dongle available to test this? I use an epox
bt-dg03.
|
| sure, I'll have a try with the dongle of a friend of mine. what's sure
| is that with my dongle on another computer, the headset doesn't work..

Sounds like it might be the fault of the dongle, or the bluez stack has
an issue with it. Did you try with M$windows?

| | What kernel version do you use? Make sure it's 2.6.10 and you have th=
e
| | -mh1 patches added.
|
| the kernel is a 2.6.10-r5 from gentoo; I don't know if it's patched, bu=
t
| I'll check

no, it's not patched with mh1. Best thing would be to use the vanilla
kernel (i.e. get it directly from kernel.org) and patch it with -mh1
patchset from bluez. I'm using gentoo, too, btw, so it should work this w=
ay.

|
| | you might also want to try to fire up alsamixer [-c1] and enable the
| | "loopback" so that you can/should hear yourself (simply fires back th=
e
| | audio to the headset directly).
|
| I tried alsamixer, and could set the volume level (and even hear the
| hissing sound become louder or weaker). I can't remember if unmuting th=
e
| loopback didn't simply work, or if I wasn't able to unmute, for a reaso=
n
| or another it didn't work :(

it should. You can use this as the simplest and fool-proof testing
method, as it does not involve any alsa library stuff beyond the
snd-bt-sco-kernel module itself, so there are not many other error
sources than the dongle and the headself itself.

Maybe there's a problem with the hci_usb implementation for your dongle..=
.

best regards,
