  • I’m in a similar situation - I’m a (retired) Unix admin and have Linux servers at home but I’m still on windows for my desktop because of OneDrive. If you use it as intended, it works really well. I can login to my laptop, my phone or either of my wife’s PC’s and all my stuff is just there.

    Yes, I’ve tried nextcloud and it’s close, but the windows sync client is (was?) broken - the upload speed throttling logic is broken and it was going to take ages to sync my data. I went to the nextcloud community and it seemed to be a known issue that know one cares about because the sync just happens in the background and it’s done when it’s done.

    As I typed this I realised that if I move to Linux desktop I don’t care about the windows sync client :-) So now I’ve just got the issue that I won’t get my wife off windows and if we’re paying for 5TB of cloud storage, I might as well use it. Yes, I know there are ways to use OneDrive on Linux, but it doesn’t look as seamless and I’d be always concerned that Microsoft will do something to break it.








  • I suggest you learn about the difference between line level and speaker level. This article seems to do a decent job:

    https://www.electronicshub.org/speaker-level-vs-line-level/

    Your boiling water analogy does not fit - water boils at 100°C (depending on air pressure). It’s like the digital signal - boiled/not-boiled, on/off, 1/0, etc.

    The output of a DAC (Digital to Analogue Converter) is a line level analogue signal and this signal has an amplitude (voltage) that can be controlled. I’m not a software or audio engineer so I don’t understand how, but my reading and own testing supports this.

    My own simple test: I have a Google Pixel 4a and an Apple USB-C DAC (dongle). If I use headphones connected to either the phone audio jack or the DAC and any “normal” music player I can listen at full volume - it’s loud, but far from uncomfortable. If I use USB Audio Player PRO and configure direct hardware access to the DAC I cannot listen at full volume - it’s too loud.


  • No - I know the difference between a DAC and an amp. The Android (or, maybe it’s just Google Pixel devices, I can’t recall) audio subsystem limits audio output. My phone max. output is about 800mV. I believe they assume all output is going to earphones and they’re trying to protect your hearing. This happens even if you’re using a USB DAC. But, there is an app called USB Audio Player PRO (the may be others) that can bypass the Android audio subsystem and send output directly to the DAC and thereby get the full DAC output - typically around 2V.
