stopping sound hangs device #496

Closed norbusan closed 5 years ago

norbusan commented 5 years ago

Currently, when I tell SuSI:

hey susi, play some music

it always plays the same music on the RPi. Then, when I say

hey susi, stop

it does stop the vlc process, but keeps it hanging somehow occupying the sound card. Asking Susi for something new does not play the detection bell sound, but hangs, too:

 1580 ?        TLl    0:09 /usr/bin/vlc -I dummy https://r4---sn-ogul7n7s.googlevideo.com/videoplayback?id=o-AGCHokAMEVnVZPxrSioJNZT
 1649 ?        S      0:00 play /home/pi/SUSI.AI/susi_linux/extras/detection-bell.wav
 1655 ?        S      0:00 sox -q -t mp3 - -d trim 0.1 reverse trim 0.07 reverse tempo 1.2 pitch 2 speed 1

This needs improvement.

Maybe we stopped VLC in a dirty way? Maybe we should tell VLC to stop the music first, then kill it?

I think this should be fixed by the susi_linux audi thread rework, later on.

saying stop doesn't stop the song in my case image

norbusan commented 5 years ago

fixed with recent merge of sound rework
