I presently have a trial version of DFX Speakers which does work, not so much by increasing all round volume but by adding an 'electronic echo' (my description) to system sounds. Volumey is somewhat similar but again i have not been able to boost beyond 100%. Ear Trumpet used to work OK but only adjusted sound for specific devices up to the already available 100%, and now the updated version will not open on my computer at all. I have tried all the settings on the PC so have started to examine some apps.
It has not much mattered up to now, as I often have external speakers connected for music, videos etc.(and I can Cast to my smart TV which provides all the volume and quality I want.) But I find the volume of system sounds is not loud enough, I can easily miss Reminder notifications for example and there are some other problems despite sound being set at 100% and easily adjusted via a Gadget. It is accepted that the volume from my TabletPC is low.
