Hello,
I bought ReSpeaker 6-Mic Circular Array kit for Raspberry Pi.
I successfully tested librespeaker examples below on Raspberry PI 3 with the 6-mic array kit.
(<LINK_TEXT text=“http://wiki.seeedstudio.com/librespeake … mples.html”>http://wiki.seeedstudio.com/librespeaker_doc/examples.html</LINK_TEXT>)
But librespeaker examples on Raspberry PI 4 with the same array kit don’t work properly as follows.
pi@raspberrypi:~/librespeaker $ ./alsa_agc_test
num channels: 0, rate: 0
Error : Not able to open output file.
pi@raspberrypi:~/librespeaker $ ./alsa_base_test
num channels: 0, rate: 0
Error : Not able to open output file.
Can you help me?
Hi @ultragen,
The error occurred due to unavailability of alsa_agc_test.wav file, make sure you have the file in your directory .
HI @salmanfarisvp,
That file is created by running the program.
The problem here is that the program on Raspberry PI 4 can’t read the channel information.
See the output.
“num channels: 0, rate: 0”
The program can read the channel info on Raspberry PI 3.
