Jetson-voice on nx whats the trick

I wanted to try jetson voice on my nx but the docker want’s r32.4.2 which is not avalable on the NX. is there another image that I am not finding? if so where do i get it?

Hi @Nick_579, here’s the link to the JetPack 4.4 Developer Preview SD card image: https://developer.nvidia.com/jetson-nx-developer-kit-sd-card-image-44-dp

Also there is newer version of jetson-voice project that has containers for JetPack 4.4.1 / 4.5 / 4.5.1:

I got things going using your git on 4.5.1 all except for a mic.

My Tascam DR-05X
Input Device ID 25 - ‘TASCAM DR Series: USB Audio (hw:3,0)’ (inputs=2) (sample_rate=44100
Output Device ID 25 - ‘TASCAM DR Series: USB Audio (hw:3,0)’ (outputs=2) (sample_rate=44100

gives me the invalid sample rate
