Dear Rainer, the commands, that you used to start slmodemd, are slightly wrong. The command should look like: sudo slmodemd -c GERMANY -a hw:0,X here you have to replace the X by the number of the codec, that the sound card uses for the modem.This number can be found by looking at the file sin /proc/asound/card0. There should be two file s starting with codec#. If you look at these files with cat, they will show at the beginning some information about the hardware. For example: >Codec: Generic 11c1 Si3054 >Address: 1 >Vendor Id: 0x11c13026 >Subsystem Id: 0x11c13026 >Revision Id: 0x100600 >Modem Function Group: 0x1 Normally the file codec#0 describes the sound device (DSP and ADC). While codec#1 describes the modem. In addition there should be some directories pcmXx, where X is a number and x is either 'c' or 'p'. Normal sound cards hva at least two directories pcm(1/2)c and one pcm1p. If there is a modem, then there are two more directories pcmX(c/p). The number X in these directory names has to be used for the X in the above slmodemd command. Example: My machine has: ls /proc/asound/card0 codec#0 codec#1 id oss_mixer pcm0c pcm0p pcm2c pcm6c pcm6p so I use "slmodemd -c GERMANY -a hw:0,6" Hope this helps, Joern
