I’ve just started using Volumio and I must say I’m incredibly impressed (hat tip to the developer) .
My current setup is a raspberry pi 4 with a hifiberry amp2 and a single speaker driver , output device set as Hifiberry Dac plus and gpio button plugin installed with assigned play and vol up and down .
I’ve so far manage to connect to my Nextcloud storage to play local files ,which works a charm and test out the stereotomono plugin.
Here in lies my problem the plugin does work at downmixing the stereo to mono, but the mixer type then defaults to none and to adjust the volume via the UI it steps in 5 when adjusting the volume and using the gpio buttons I can only raise the volume to 31, I understand this is because it is not compatible with softvol and probably defaults to hardware volume control
This is obviously the same if I disable the plugin reset back to Hifiberry Dac Plus only and have its default mixer type as hardware I can only raise the volume to 31 when using the Gpio buttons and it step in 5’s in the UI.
If use the software as my volume mixer type i can raise the volume with the Gpio button all the way to 100 in steps of 1 and also in the UI .
I’ve read that I could use asound.conf to convert stereo to mono as described here https://support.hifiberry.com/hc/en-us/community/posts/360001927178-Yet-another-Amp2-Mono-Output-thread?mobile_site=true however I’m not sure how well this plays with the existing softvol setup present in the asound.conf file . Of course using software control has its downsides and it does prevent me from potentially using the equalizer plugin but is this my only options ?
I not sure what is the best option available or if there are any other options, but I would be grateful for any help .
thanks in advance .
