My Qimedia Android TV have a control app that mirrors your monitor/tv screen to your smartphone via Bluetooth. So you can control your device from smartphone. But it was slow.

Posting on another thread so will duplicate here...

Since your setup should be stable now, you may want to try this SQ tweak. It's probably a tweak utilized on the high-end streamers... I believe this is from the Windows AudiophileOptimizer dude. It works terrifically for I.
For those who don't know, RAMdisk is one of the most high-performance methods for audiophiles in the world, and although I've never read anything about it in this forum and only have a personal friend who has tested before me, I've read a lot, a lot , much information in international scope, where it seems that the theme is more evolved. Reducing latency and high throughput is only a small part of the benefits. If that weren't enough, I've never heard any "original" setup, with SSD, SD card, M.2, or anything else, that delivers audio quality as good as RAMdisk. For me, it's the best, but what I don't know is if there are different RAM models that deliver different sonorities (Corsair vs. Kingston; Kingston vs. Crucial; Corsair vs. GSkill; e.g.).

So what you want to do in go into Squeezelite settings and fiddle with the buffer settings. I have not took a screenshot for my guide yet, but you should be able to locate. I use a 1:1 ratio since I mainly use uncompressed PCM.

This link should help you out. I'll expand more when my guide is finished.

Interesting behaviour on the Squeezlite buffer, but that's not really a RAMdisk. In theory, the best possible performance should come form having a modest buffer, but have your music stored in a 'real' ramDisk (i.e. block storage on xRAM, not just a tmpfs instance. There's a decent article about it here....

What's picore? Crossfeed or not depends on the app, or if you're lucky you have a headphone amp with crossfeed like a Meier.

I'm hoping there is a software plugin that does crossfeed in the digital realm. While I have an old Meier amp, my newer amps dont have crossfeed. Seems like no newer amps do.

SPL Phonitor does as far as I know, even to the point you can't turn it off on some of their models.

Foobar2000 has a crossfeed plugin but it runs only on Windows afaik.

I guess you could check the picoreplayer forums and ask around.

I'm mainly a battery-only type for ultimate SQ purity. So my sound philosophy is LiFePO4 batteries
I do like your setup and I was thinking to do a similar setup myself too, but running RPi on batteries will not improve sound quality! RPi is powered via 5V source, so you're probably using one single 18650 3.6...4.2V battery with a boost converter that regenerates a higher voltage (+5V) to power the RPi. You can use a scope and see if the ripple & noise of this newly generated 5V is lower than the ripple & noise of the original RPi supply, but I doubt there will be a significant difference.

However, using batteries as a backup source for power loss is a great advantage and I am thinking to do the same myyself too.
