Possible audio problem? Terminates after "How can I be of service, #myname"?

[Kevin Lin]

Hi, 

I've had a little hard time trying to setup Jasper on my Pi 2, and now it seems it finally starts working! Jasper was able to detect what I was saying:

client.stt:Transcribed: ['JASPER']

However, it wasn't replying or doing anything else. There were also a lot of errors before detection started. So I went to tts.py and changed the 

aplay -D plughw:1,0

line to:

aplay -d plughw:1.0

Now when I start Jasper, the program will tell me "How can I be of service, Kevin?", before it terminates (does not listen for speech inputs anymore). I changed -D to -d because -D gave an error when I tested it on a separate .wav file I recorded for testing.

Might that be what the error is about? I tried to change -D back to -d, but my program still terminated (without saying "How can I be of service, Kevin?"). I'm not sure what's happening here as I don't remember changing anything other than the line in tts.py. 

Here is the full error log that I get now:

Any help would be really appreciated!

Update: 

I found out a fix to the error on line 75 (invalid input device). I have to re-plug in my USB microphone into the Raspberry Pi after every run (and subsequent quit), or else I would receive that error. Does anyone know why?

However, I'm still receiving the ALSA errors; the only difference is that instead of terminating, the program continues to listen.

i found that the tts.py didn't work for my setup. i removed the "-hw" and its arg from the play() function as follows:

cmd = ['aplay', str(filename)]

That fixed my system. I hope it works for yours

Thanks you so much!! This made it all work for me.
