snowboy: Device or resourse busy

[sdetweil]

@banbutcher snowboy will use arecord, not aplay…

so ps -ef | grep arec

[banbutcher]

heres the result of that:

pi@MirrorPi:~ $ ps -ef | grep arec
pi         765 21495  0 16:23 pts/1    00:00:00 grep --color=auto arec
pi       25903     1  0 13:36 pts/0    00:00:00 arecord -D plughw:1 -q -r 16000 -c 1 -t wav -f S16_LE -

this is with MM shut down.

[sdetweil]

@banbutcher so arecord is hung ( parent is 1) … kill it

sudo kill -9 25903

[banbutcher]

yup, thats done it. Any idea what would cause it to hang?

[sdetweil]

@banbutcher no… i see it end unexpectedly more than hang, 999 times :1

[banbutcher]

and you can tell from that output that it hung?

I think its when i refresh MM, it doesnt close snowboy properly so when MM refreshes snowboy is open already and hangs?
EDIT* (I tested the theory and if i refresh my MM then snowboy goes into that error loop.)

would that make sense?

[sdetweil]

@banbutcher yes, seems logical. Another platform cleans up on refresh.

[banbutcher]

could there be a way to shut it properly if the mirror is refreshed?

[sdetweil]

@banbutcher yes, but coding required

[banbutcher]

@sdetweil as always thanks for your help!

i think i need to bring in the expert: @Bugsounet have you any thoughts?

@banbutcher don’t know really, in all case it will be restart
I have coded this code ‘on error… Retry and make a loop (is needed)’
And I code ‘stop snowboy every 12h snowboy and restart it (and verify any error)’

So the code is normally controlled by the library
