Hello,
Does anyone think there will be a security type of OS built for the pinephone, like a Graphene but for the phinephone ? I'm sort of into that type of stuff and figure the phonephone would be a great platform to build something like that on.I could be wrong, and maybe I'm dreaming of something that can't or won't be created.

Any thought on what impact if any the acquisition of arm by Nvidia will have on the community?

I just recorded 9 hours of audio overnight using a USB soundcard only to find it was mostly power supply trash.  This didn't happen on batteries.


I'm scratching my head thinking my microphone preamp had started oscillating, then I realized it was hum.  But not normal 60 or 120 hz hum, this is from a switchmode power supply.  I suppose you could argue that the USB sound card should have better filtering since it's trying to do analog stuff in a digital world, but it just assumes the USB power is clean.  Is there an obligation to provide clean power?  The preamps are battery powered still, it's getting picked up in the sound card.  Which is a $10 cheapie from Aliexpress.  I do have a better one I could try.

OK, with my StarTech USB sound card some of the high frequency stuff is filtered out, it sounds more like 120 hz hum, which of course it isn't.  It's like there's some capacitance there but only enough to take out the high frequencies.

I'm recording with sox and having it normalize the level so the hum becomes most of the signal I recorded.

Just guessing, if you settled for running the soundcard internals on about 4.5 volts instead of 5.0, you could use a PNP pass transistor in linear mode with some active filtering to clean that up. You pull the base of a PNP down to make it conduct so it has less overhead than an NPN. An old LM723 chip has quite good active filtering if you use a few stages of pass transistors to provide current gain. I don't have a spare one of those barrel plugs though.

I live in Switzerland and often buy products directly in China from Aliexpress.com. They have an excellent store, and shipping via Aliexpress standard shipping is cheap, I guess around 10 USD for a 150 USD device. Shipping time over Aliexpress standard shipping is about two week and reliable. You can send products also through China Post, which is even cheaper, but takes more than a month. When the PinePhone is produced in China or Asia, why not to choose Asias best store with Asias best shipping method?

I am running Mobian on an SD card and i would like to change the ring tone and also the Alarm Clock tone.  My plan was to replace the default sound file with what I wanted but I am struggling to find the their locations.  I will keep on searching but if anyone by chance knows will you please post it here?

Note: I am using the default "Clocks" app.

So I wasn't initially aware of the existing trackpad issues, and so a quick google search brought me to this pinebook pro forum post
I was so eager to fix the issue that I didn't really notice this wasn't a pine TAB forum as the OP was simply commenting on how a linked procedure worked for them.

In any case, now my KB/Trackpad are completely unusable. 
I'm able to repeat the procedure, so the basic USB communication is still there. Also the keyboard reacts on some keys but the resulting signal is nothing related to the actual key pressed.

I'm wondering if there's any way to get a hex dump of the actual keyboard/trackpad from the pinetab in order to revive my now botched keyboard...

When I plug in power through the hub, the phone will say it’s charging (in the phosh gui, anyway), but the charge percentage goes down.

Hi ,

I am new to this forum and the world of linux.
I am looking for some general directions for installing a software on pine book pro with (factory) Manjaro.
The software is Monero GUI:
https://github.com/monero-project/monero...-a-package

Is this feasible?

I sometimes need several attempts to start the PineTab after shutdown. I don't know if it's the "video issue" or something else. Normally it starts after 2s of holding down the power button, but sometimes it needs 10s+ several times. Have you experienced the same behavior?

Edit: Currently Mobian, running internal emmc but had the same experience with UT also...
