Audio output balance slider start with incorrect position for HDMI port
After opening the control center/sound, the "Balance" slider is always positioned in the middle no matter what the volume values are for the Left/Right channel of the HDMI. Nevertheless, there's no such problem neither for the internal speaker nor the headphone. I set the slider to left, close the control window and then re-open it to sound settings, the slider is not updated correspondingly.
Steps to reproduce:
- Plugin the HDMI cable
- Open GNOME Settings
- Go to Sound tab
- Select the HDMI as the audio output device if it's not automatically selected
- Slide the balance slider to any position other than the middle.
- Close the control center and reopen.
- Check the balance slider again for the HDMI output.
