I am trying to install Jasper (Jasper is an open source platform for developing always-on, voice-controlled applications) on Raspberry Pi 2 (Jessie). I have a mic to give the commands, but it does not seem to be working. As per the documentation
Plug in your USB microphone. Let’s open up an ALSA configuration file in vim:
sudo vim /etc/modprobe.d/alsa-base.conf
Change the following line:
options snd-usb-audio index=-2, to this:
options snd-usb-audio index=0
Back in the shell, run:
sudo alsa force-reload(Does not work, says "could not find alsa")
Next, test that recording works (you may need to restart your Pi) by recording some audio with the following command:
arecord temp.wav(throws error "arecord: main:722: audio open error: No such file or directory")
I have looked at one of the solutions on this site, but it did not work for me.
The Jasper instructions are: Manual Installation
mic: Kinobo USB Microphone
speaker: Logitech S150 USB Speakers with Digital Sound
indexworks only if used with all drivers); please use the
slotsmethod instead, and file a bug with Jasper.
indexoptions are no longer needed.
/dev/snd/? Is your user in the audio group?
