hi, I bought a ReSpeaker 4-Mic Array for Raspberry Pi. I have a 64-bit operating system. when I do the ./install_arm64.sh it will tell me there is an error because I run it already and the error is that the directory /etc/voicecard is already excising. when I do the command record -L I get this :
pi@raspberrypi:~ $ arecord -L null Discard all samples (playback) or generate zero samples (capture) lavrate Rate Converter Plugin Using Libav/FFmpeg Library samplerate Rate Converter Plugin Using Samplerate Library speexrate Rate Converter Plugin Using Speex Resampler jack JACK Audio Connection Kit oss Open Sound System pulse PulseAudio Sound Server upmix Plugin for channel upmix (4,6,8) vdownmix Plugin for channel downmix (stereo) with a simple spacialization default Playback/recording through the PulseAudio sound server playback ac108 usbstream:CARD=b1 bcm2835 HDMI 1 USB Stream Output usbstream:CARD=Headphones bcm2835 Headphones USB Stream Output
This is not what I need to get if you look in the documentation (ReSpeaker 4-Mic Array for Raspberry Pi - Seeed Wiki)
What can i do to fix this?
