Segmentation fault

[WeeJeWel]

On a Raspberry Pi, Raspbian jessie, using a USB microphone interface that does work with arecord.

When executing ./witd-arm -i plughw:1,0 -v 10:

[wit] initialized sox: 14.4.1
[wit] init state machine
[wit] initialized with device: plughw:1,0

[wit] Sending speech request with content type: audio/raw;encoding=signed-integer;bits=16;rate=48000;endian=big

Any idea?

Thanks for the report. Do text queries work? (http://localhost:9877/text?q=hello&access_token=***) And what about queries with end-of-speech detection disabled? (http://localhost:9877/start?access_token=*** and http://localhost:9877/stop)

stop and text works.

start without autoend outputs a lot of numbers:

We haven't had a chance to test witd-arm on Jessie yet. I updated witd-arm so that it contains debugging symbols. If you have time could you try running it inside gdb and showing a backtrace? (gdb --args ./witd-arm -i plughw:1,0 -v 10, then run, do the http request with autoend=true, and do bt when you get a segfault). This way we might be able to see what is failing.

Hi Emile, we are looking into the issue.

[WeeJeWel]

Awesome, thanks. If i can help, let me know!

[martinraison]

I'll try to reproduce your issue today and let you know what I get. Thank you for your patience!
