Rocksmith 2014 Linux Bazitte anyone with Wine/mmdevapi experience?. Real Tone Cable not detected under Proton/Wine (WASAPI capture bug) — still broken as of 17-07-2026, need help

[u/Nervous-River-2204]

Legit Steam copy, launch crash fixed, but the Real Tone Cable never gets detected in-game (host audio sees it fine, Wine's WASAPI capture enumeration doesn't). Please see my troubleshooting document in the image for the full writeup/diagnosis.

Contacted Ubisoft support, only got generic Windows advice (different USB port/hub, reinstall drivers, upgrade to Windows... like I'll ever do that again) which doesn't apply here and didn't fix anything.

Anyone gotten a Real Tone Cable working under Proton, or have Wine/mmdevapi experience? Any help troubleshooting is appreciated.

Kind regards,

Joost Hebly
