Hi Dave,

Just wanted to give you an update after going through everything again on my Kindle Paperwhite 4 (10th Gen), running firmware 5.16.2.1.1 (HF).

I reinstalled the Sox v1 package and confirmed that all the expected files are there, including sox and soxi in /mnt/us/extensions/sox/. However, when I try to run either of those binaries from the terminal, I get this error:

-sh: /mnt/us/extensions/sox/sox: not found

Even though the file exists and has execute permissions, the system refuses to run it. I also checked for /lib/ld-linux.so.3, which might be needed to run the binary, and it’s not present on the device.

So at this point, I have the files in place, but the sox binary itself won’t run at all. This might be due to how it was built, or maybe there’s something in the HF environment that prevents it from loading properly.

Let me know what you’d like me to try next. I’m happy to test anything or provide more info if needed.

Thanks again for your help!

You could try running "ldd /mnt/us/extensions/sox/sox" and see what if any missing libraries are reported.

You could also run "uname -a" and tell me what it shows.

Here on my PW4 with an earlier firmware it shows:

Code:
Linux kindle 4.1.15-lab126 #1 SMP PREEMPT Tue Nov 27 03:27:44 PST 2018 armv7l GNU/Linux
I would expect yours to be different on HF firmware.
