Re: [Ekiga-devel-list] full-duplex problem with USB headset

["A. James Lewis" <james fsck co uk>]

Hi all,

I have encountered this same problem with 2.6.17.13... is anyone aware
of a solution by now?.. I am in the process of upgrading to 2.6.18.5 see
if that will help, however if the problem has remained since February I
am not sure how much chance there is that this will help.

Any suggestions greatly appreciated.

James.
