I can't get the CAT control to work with Yaesu FT991A in Linux version (Ubuntu 24.04). I have tried both Native and Hamlib settings. I have made the serial settings as described in the manual. Program version is 1.0.498. Other Linux programs (WSJT-X, FreeDV etc) are working, also Windows version is working. Automatic self-check: - Too many decoder threads: You have 7 threads on 8 cores. Beyond about 6 decoding does not get faster, but CPU is taken away from audio. ## Bug Report — Decodium 1.0.498 ### User Description ### System Info ``` OS: Ubuntu 24.04.4 LTS x86_64 Qt: 6.11.0 App: Decodium 1.0.498 Screen 0: 2560x1440 @96 DPI (scale 1.00) AudioIn: Built-in Audio Analoginen stereo AudioIn: PCM2903B Audio CODEC Analoginen stereo AudioOut: Built-in Audio Analoginen stereo AudioOut: PCM2903B Audio CODEC Analoginen stereo ``` ### QML Errors (3) ``` 2026-07-25T16:38:57 file:///tmp/.mount_DecodikeoFoF/usr/bin/qml/decodium/components/SettingsDialog.qml:2804:29: Unable to assign [undefined] to bool 2026-07-25T16:39:13 file:///tmp/.mount_DecodikeoFoF/usr/bin/qml/decodium/components/SettingsDialog.qml:2361:29: Unable to assign [undefined] to bool 2026-07-25T16:39:13 file:///tmp/.mount_DecodikeoFoF/usr/bin/qml/decodium/components/SettingsDialog.qml:2307:29: Unable to assign [undefined] to bool ``` ### Auto-Analysis No known bug patterns matched.
