    No audio from robot (low volume)Reachy speaker volume set too low by defaultIncrease Reachy speaker volume to maximum
    No audio from robot (device conflict)Another application capturing Reachy speakerCheck animation-compositor logs for "Error querying device (-1)", verify Reachy speaker is not set as system default in Ubuntu sound settings, ensure no other apps are capturing the speaker, then restart the demo
    Image-generation fails on first startTransient initialization issueRerun docker compose up --build -d to resolve the issue

    If you have any issues with Reachy that are not covered by this guide, please read Hugging Face's official troubleshooting guide.

    NOTE

    DGX Spark uses a Unified Memory Architecture (UMA), which enables dynamic memory sharing between the GPU and CPU. With many applications still updating to take advantage of UMA, you may encounter memory issues even when within the memory capacity of DGX Spark. If that happens, manually flush the buffer cache with:

    sudo sh -c 'sync; echo 3 > /proc/sys/vm/drop_caches'

    For latest known issues, please review the DGX Spark User Guide.
