Summary: IEC958 output is not muted when plugging in headphones
but volume is increased
Product: neon
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Packages User Edition

SUMMARY
When plugging my headphones into the front 3.5 mm jack of my desktop pc the
output of my speakers that are connected via IEC958 (aka S/PDIF) is not muted
but actually increased.
STEPS TO REPRODUCE
1. Have music playing over IEC958. Volume can be adjusted. The only active
pulseaudio sink is alsa_output.pci-0000_00_1b.0.iec958-stereo
2. Plug in headphone in front 3.5 mm jack.
3. Music is playing through headphones and this volume can be adjusted. The
only pulseaudio sind is alsa_output.pci-0000_00_1b.0.analog-stereo. BUT
speakers are still playing, the volume increased immensly and volume cannot be
adjusted by any known means.
OBSERVED RESULT
Sound is still playing over speakers
EXPECTED RESULT
Sound is only playing through headphones and speakers are muted.
