The fact that the code is such a horribly mangled mess explains why they abandoned it. In the source code there is no mention of whether this is still looking for ALSA or ? The problem is exclusively the sound interface - it does not seem to exist. (My setup is Fujitsu T580 4g i5 dual boot, Ubuntu 14.04 xubuntu 32bit Saga_of_Fail) The first answer, of course: wipe Ubuntu and install win7 - it just works. The sound most definitely works under windows 7. I have almost the same problem, using the e173 modem.
other sample formats can be gotten from aplay -help
TIP:-if you hear scratcy sound instead of human voice, change S16_LE to S16_BE.This is the sample format. Maybe modem-manager-gui might also implement voice someday The mmcli developers are trying to implement it in ModemManager.I think If you want to keep you modem online so you can recieve calls, then keep both terminals open You should now hear sound from your speakers and you can also speak into theĪfter you are done with your call, you can hangup with: AT+CHUP
Go back to the first terminal and dial the number: ATDxxxxxxxxxx įrom the same dialogue terminal he route audio: AT^DDSETEX=2 The audio sampleformat, S16_LE is 'Signed 16 bit Little Endian', Rate 8000 Hz, Mono it depends on the response from AT^CVOICE? other modems may require S16_BE Open another terminal and enable microphone: Open another terminal and enable audio: sudo cat /dev/ttyUSB1 | aplay -f S16_LE The -c means local echo on, making AT commands visible as you typeįind the audio sample formats supported by your modem: AT^CVOICE?Ī reponse of 0,8000,16,10 means the rate is 8000hz Usually, the dialogue port (ie 1st port) is /dev/ttyUSB0, audio port (ie 2nd port) is /dev/ttyUSB1 and sms & internet aka data port (ie 3rd port) is /dev/ttyUSB3
