Hi,

I have the latest raspian jessie installed on Rspberry pi 2 (Feb 2016 release).

I got a problem on the first step itself which was setting up some alsa config.

The alsa config /etc/modprobe.d/alsa-base.conf is missing on jessie.

I got some other config /usr/share/alsa/alsa.conf where i could not see the mentioned lines.

So I decided to go ahead with rest of the process and everything went well.

I setup PocketSphinx as stt engine.

Now when I run /home/pi/jasper/jasper.py

I get the following long error? Can someone help?

This is just an error showing that you have not setup your audio correctly.

Hi @Matthew,

Thanks for your answer.

But I don't understand why I this error :

ALSA lib pcm_dmix .c:1022:(snd_pcm_dmix_open) unable to open slave

My .asoudrc :

pcm.dmixed {
    type dmix
    ipc_key 1024
    ipc_key_add_uid 0
    slave.pcm "hw:1,0"
}
pcm.dsnooped {
    type dsnoop
    ipc_key 1025
    slave.pcm "hw:0,0"
}

pcm.duplex {
    type asym
    playback.pcm "dmixed"
    capture.pcm "dsnooped"
}

# Instruct ALSA to use pcm.duplex as the default device
pcm.!default {
    type plug

Thank you

What hardware are you using?

First, remove the .asoundrc

Then setup the hardware correctly in alsa.conf, and reboot. Join us in slack, and I can help more.
