Basically this happens when we are muting/unmuting the ALSA master channel instead of PA master channel. Muting ALSA master will also mute PA master (which may even mute ALSA PCM as a consequence). Unmuting ALSA master will unmute such channel but not PA master. The correct way is to mute/unmute PA master. The current KMix/KMilo code in master and R14.0.x does not support PA well and this problem is a consequence of that. I have recently prepared a full fix that will go in master branch probably tomorrow, but given that it brings along a significant API change, it won't make it to R14.0.x branch. Anyhow a small section of the fix will be backported to address some of the issues I found will fixing PA support for R14.1.0. For the time being (till R14.1.0 is out - possibly end of 2020) you have the following choices: 1) you can mute/unmute from the KMix slider LED, this should work fine with PA already 2) you can open KMix mixer windod -> Settings -> Configure global shortcuts and remap the "toggle mute" keyboard shortcut to some other key combination. Do not use "XF86AudioMute" key, since this is normally used by KMilo and therefore may not work 3) you can create a script that calls "dcop kmix Mixer-1 toggleMasterMute", this will mute/unmute the PA master channel. You can add an input action tied to a keyboard shortcut to call this easy. 4) if you are on debian-like distro, you could switch to Slavek's PTB packages and get the latest R14.1.0-dev packages at regular intervals. This will bring you the complete fix in a few days Cheers Michele --------------------------------------------------------------------- To unsubscribe, e-mail: trinity-users-unsubscribe(a)lists.pearsoncomputing.net For additional commands, e-mail: trinity-users-help(a)lists.pearsoncomputing.net Read list messages on the web archive: http://trinity-users.pearsoncomputing.net/ Please remember not to top-post: http://trinity.pearsoncomputing.net/mailing_lists/#top-posting
