I would recommend to try to re-compile soundmodem from sources. The current sources version is 0.14. If that doesn't help, I'd recommend you back down to less of a bleeding edge distro. I chose the exact opposite approach and have everything running on Centos 5.3 but it took a lot of work. --David Christof Bodner wrote: > Hi Dave, > > I am using the soundmodem provided by the Ubuntu team > $ dpkg-query -W soundmodem > soundmodem 0.10-6 > > This is the output of soundmodemconfig: > > on_configtree_selection_changed > selection: cfg: default chan: Channel 0 > Modulator: afsk Demodulator: afsk > Modulator: parameter bps value 1200 > Modulator: parameter f0 value 1200 > Modulator: parameter f1 value 2200 > Modulator: parameter diffenc value 1 > Demodulator: parameter bps value 1200 > Demodulator: parameter f0 value 1200 > Demodulator: parameter f1 value 2200 > Demodulator: parameter diffdec value 1 > Minimum sampling rate: 9600 > Audio IO: type alsa > ALSA: Using sample rate 9600, sample format 2, significant bits 16, > buffer size 3276, period size 102 > ALSA: Using sample rate 9600, sample format 2, significant bits 16, > buffer size 3276, period size 102 > Real sampling rate: 9600 > Joining TxThread > Joining RxThread > Releasing IO > Modulator: afsk Demodulator: afsk > Modulator: parameter bps value 1200 > Modulator: parameter f0 value 1200 > Modulator: parameter f1 value 2200 > Modulator: parameter diffenc value 1 > Demodulator: parameter bps value 1200 > Demodulator: parameter f0 value 1200 > Demodulator: parameter f1 value 2200 > Demodulator: parameter diffdec value 1 > Minimum sampling rate: 9600 > Audio IO: type alsa > ALSA: Using sample rate 9600, sample format 2, significant bits 16, > buffer size 3276, period size 102 > ALSA: Using sample rate 9600, sample format 2, significant bits 16, > buffer size 3276, period size 102 > Real sampling rate: 9600 > delete event > on_configtree_selection_changed > Modulator mode: afsk > Demodulator mode: afsk > Packet IO mode: MKISS > Joining TxThread > Joining RxThread > Releasing IO > selection: cfg: - chan: - > podex@rosi-atom:~$ sudo soundmodemconfig -v 4 > on_configtree_selection_changed > selection: cfg: default chan: Channel 0 > Modulator: afsk Demodulator: afsk > Modulator: parameter bps value 1200 > Modulator: parameter f0 value 1200 > Modulator: parameter f1 value 2200 > Modulator: parameter diffenc value 1 > Demodulator: parameter bps value 1200 > Demodulator: parameter f0 value 1200 > Demodulator: parameter f1 value 2200 > Demodulator: parameter diffdec value 1 > Minimum sampling rate: 9600 > Audio IO: type alsa > ALSA: Using sample rate 9600, sample format 2, significant bits 16, > buffer size 3276, period size 102 > ALSA: Using sample rate 9600, sample format 2, significant bits 16, > buffer size 3276, period size 102 > Real sampling rate: 9600 > Joining TxThread > Joining RxThread > Releasing IO > Modulator: afsk Demodulator: afsk > Modulator: parameter bps value 1200 > Modulator: parameter f0 value 1200 > Modulator: parameter f1 value 2200 > Modulator: parameter diffenc value 1 > Demodulator: parameter bps value 1200 > Demodulator: parameter f0 value 1200 > Demodulator: parameter f1 value 2200 > Demodulator: parameter diffdec value 1 > Minimum sampling rate: 9600 > Audio IO: type alsa > ALSA: Using sample rate 9600, sample format 2, significant bits 16, > buffer size 3276, period size 102 > ALSA: Using sample rate 9600, sample format 2, significant bits 16, > buffer size 3276, period size 102 > Real sampling rate: 9600 > Joining TxThread > Joining RxThread > Releasing IO > Modulator: afsk Demodulator: afsk > Modulator: parameter bps value 1200 > Modulator: parameter f0 value 1200 > Modulator: parameter f1 value 2200 > Modulator: parameter diffenc value 1 > Demodulator: parameter bps value 1200 > Demodulator: parameter f0 value 1200 > Demodulator: parameter f1 value 2200 > Demodulator: parameter diffdec value 1 > Minimum sampling rate: 9600 > Audio IO: type alsa > ALSA: Using sample rate 9600, sample format 2, significant bits 16, > buffer size 3276, period size 102 > ALSA: Using sample rate 9600, sample format 2, significant bits 16, > buffer size 3276, period size 102 > Real sampling rate: 9600 > Joining TxThread > Joining RxThread > Releasing IO > delete event > on_configtree_selection_changed > Modulator mode: afsk > Demodulator mode: afsk > Packet IO mode: MKISS > selection: cfg: - chan: - > > I started the oscilloscope twice and the spectrum analyzer once.
