  • #### My Rationale
  • Occasionally, audio from a very useful proprietary application is too quiet to be audible. This is impossible to remediate at the application level because:
  • 1. I am unable to request that the application author(s) implement a method of increasing the volume >100% intra-application, because it has no issue tracker.
  • 1. I do not want to record the audio and manually increase the volume > 100 %, because that would be inconvenient.
  • #### My Question/Desire
  • Instead, hopefully it is achievable at the OS level. Consequently, [how] can I set any and/or all sound channels (especially the media channel) to > 100 % volume?
  • ---
  • #### The Feasibility Of The Desired

However, I've been unable to ascertain confidently what it is, nor which of myriad projects sharing that name is relevant.

How to increase the volume for all audio streams >100%?
#### Rationale

Occasionally, audio from a very useful proprietary application is too quiet to be audible. This is impossible to remediate at the application level because:

1. I am unable to request that the application author(s) implement a method of increasing the volume >100% intra-application, because it has no issue tracker.

1. I do not want to record the audio and manually increase the volume >100%, because that would be inconvenient.

#### Query

Instead, hopefully it is achievable at the OS level. Consequently, how can I set any and/or all sound channels (especially the media channel) to >100% volume?
