Not related to rebase, but more of an FYI as I went through my testing, when I first implemented audio in the rdesktop containers the read aloud feature was emphasized by a blind user. You might want to look into the possibility of fixing this.

Just tested and it's most likely a perm issue. I looks like it is downloading the data but can't write/transfer it. I just need to figure out where exactly it's trying to write it to.

Well, it downloaded the onnx file into the config folder. But something else breaks after. The log I get is:

I'll dig in later

I got it to work, but no idea why it fails in calibre. I'll report to them.

Basically, it needs to download 2 files and place them into /config/.cache/calibre/piper-voices:

• https://huggingface.co/rhasspy/piper-voices/resolve/v1.0.0/en/en_US/libritts/high/en_US-libritts-high.onnx
• https://huggingface.co/rhasspy/piper-voices/resolve/v1.0.0/en/en_US/libritts/high/en_US-libritts-high.onnx.json

It successfully downloads the onnx file, but somehow fails on the json one. Manually downloading the json file made it work:

docker exec -it calibre bash
curl -L https://huggingface.co/rhasspy/piper-voices/resolve/v1.0.0/en/en_US/libritts/high/en_US-libritts-high.onnx.json -o /config/.cache/calibre/piper-voices/en_US-libritts-high.onnx.json
chown abc:abc /config/.cache/calibre/piper-voices/en_US-libritts-high.onnx.json
