I'm trying to decode DTMF (phone tones) from my linux sound card. I tried to use multimon. But when I run "multimon -a DTMF" as it says in the documentation, it doesn't work. Does anyone know how to use "multimon", or any other program that works the same in linux?
$ multimon -a DTMF
multimod (C) 1996/1997 by Tom Sailer HB9JNX/AE4WA
available demodulators: POCSAG512 POCSAG1200 POCSAG2400 EAS AFSK1200 AFSK2400 AFSK2400_2 HAPN4800 FSK9600 DTMF ZVEI CCIR SCOPE
Enabled demodulators: DTMF
open: No such file or directory
When I run "strace -e file multimon -a DTMF 2>&1 | grep ENOENT", this is the output:
$ strace -e file multimon -a DTMF 2>&1 | grep ENOENT
access("/etc/ld.so.nohwcap", F_OK) = -1 ENOENT (No such file or directory)
access("/etc/ld.so.preload", R_OK) = -1 ENOENT (No such file or directory)

access("/etc/ld.so.nohwcap", F_OK) = -1 ENOENT (No such file or directory)
open("/dev/dsp", O_RDONLY) = -1 ENOENT (No such file or directory)
Can you run
strace -e file multimon -a DTMF 2>&1 | grep ENOENT
