No, I did not transmit to the ether, only to my loudspeakers. It seemed that there was a holdup, as there were no packets for some secondes and then came a lot of them. But it could also be sent this way from the ahavi and cups daemons which produce them. It did not change the behaviour after restarting having unloaded the ax25 and mkiss modules. 73 de OE8BCK, Christof Am Sonntag, den 13.09.2009, 11:26 -0700 schrieb Dave Platt: > Christof Bodner wrote: > > Hi, > > > > Soundmodem stopped to work in Ubuntu 8.04, in 7.10 it works fine with > > OSS.
