Binary search failed

🐛 Bug Report

When you encode in one hardware and try to decode on a different machine it will fail to decode even using the same versions for all libraries.

To Reproduce

1. Encode a file on a machine that has no GPU or ir a notebook (I'm not sure what hardware difference is causing the error TBH)
2. Try to decode the file on a machine that has a GPU or is a desktop (must be totally different hardware)

Expected behavior

It should decode as both machines are using encodec 0.1.1 and torch 2.4.1 and python 3.9.13

Actual Behavior

The decoding fails with this error:

It has happened multiple times using different machines. I have old encoded files that I am unable to decode on any machine now.

Your Environment

• Python and PyTorch version: python 3.9.13, torch 2.4.1
• Operating system and version (desktop or mobile): windows 11 on both machines
• Hardware (gpu or cpu, amount of RAM etc.):
  machine A - encoder) 16gb, notebook, Intel(R) Pentium(R) CPU 4405U @ 2.10GHz
  machine B - decoder) 48gb, AMD Ryzen 5 3600 6-Core Processor
