Errors I met to use AIY Voice Kit from Google

Errors I met.

Couldn’t use my 32GB Micro SD card.

Couldn’t authorize “AIY-voice-kit-python/src/examples/voice/”.

Re make new project on Google Chrome and used ssh of Chrome extention solved OAuth authorizing problem. 😄

(Used default Micro SD card.)

ssh commands memo

ssh pi@ipAdress #connect to raspberry
#cp from Local to Remote
scp '/home/masa/Downloads/client_id.json' pi@ipAdress:/home/pi

To solve error message below
masa@em-p:~$ ssh pi@

Setting for Native Instruments Traktor Scratch Pro 2 Audio Latency and Jumpiness On Nec Lavie (Dee-Jay)

Fundamental resources to do this.


First download this tool.


Set processor schedule, prior background service than program.
Computer > Property > Advanced System Setting! > Advanced tab! > Performance > check Background service

Checked diagnostics of A/I control panel.
Latency 1500ms when 96khz, 1024 buffer samples
It’s almost same when 44.1khz,512 samples.

My present situation is seldom jumpiness.

Next should try BIOS ?

No, just stop one driver was enough for me.

Used LatencyMon Drivers analysis.
My case “ACPI.sys for NT ACPI driver” was cause.

Stop this driver from Device driver > Battery > Microsoft ACPI-Compliant Control Method Battery > Right click and stop this driver

Solved my latency problem.
This is much worse than using wifi adapter.LoL.



Next time I used Traktor recording error occurred again.

Cause windows update, I don’t know.

Perhaps i8042prt is being used by Internal Keyboard and this is the cause…

I wanted to update BIOS but not supplied by NEC “NEC Lavie LL700/VG6W”.

Found newer version of Traktor


Driver version updated from 2.9.6 to 4.2.0.

Firmware is the same.

The problem still persisting…
