Hi, do you have planned to use 5.10 kernel?

 

[KonstaT]

Hi, i have been using Lineage OS 17 for a while. I have problems with my wifi signal it keeps dropping. But i have no problems with using the ethernet (im sharing my laptop's wifi connection to ethernet) i restarted my raspi and then got stuck on bootloop and i dont know the reason. So what i did is i downloaded the Lineage 18 and installed gapps tv stock now my computer cant detect the ethernet connection, and im currently connected to my laptops hotspot i wanted the ethernet port to work. Checked eth0 via if config it says that its Up,broadcasting,running,multicast but on my laptop network adapter settings there is no device that is connected on my laptops ethernet port. Anu thoughts on how to fix this?
And any updates on the hardware video decoding? Videos stutter when its decoding 1080p videos. Thank you so much. Love your works

Difficult to say what could be the issue with ethernet. Could be a lot of things including your computer (rebooting everything is of course the first thing to try).

http://disq.us/p/2flzmq1 is the latest discussion on hw video dec/enc with relevant links.

Following manual and looking for a way to boot in TWRP I am unable to find Advanced Restart entry in Developer options


edit
Found in under "Gestures" settings, not in Developer Options

Yes, this was moved in LineageOS 18. FAQ does point you to the right place, though.

Hi, do you have planned to use 5.10 kernel?

Yes, I've had it running all the way from 5.10.0 version. 5.10 also brings supports for DSI display with KMS driver used with hw accelerated graphics (among various other improvements to KMS support) so I'm looking forward to this as well.

There's no sdcardfs for 5.10 which means using the new quota storage. There's a strange storage issue with this after installing gapps. Some apps don't have access to internal emulated sdcard after installing gapps. It's fine without gapps, I think it's fine with gapps after formatting /data in TWRP (vs. just doing a normal factory reset). Not sure what is the issue exactly and haven't really had time to look into it more closely.

5.4 is the newest kernel version Android supports for R. 5.10 is actually S (Android 12) kernel so there's that, too.

I use Pi4 as I car head unit with USB DAC, Topping D10S in particular as USB-Optical converter going further to DSP. And what I noticed is that Lineage OS outputs sound as 96khz by default, that is different from all other Androids I used. Is this normal behavior? I'm getting pretty rough jitter, I wonder if this something to do with 96khz upsampling? I plan to try Hifiberry Digi to get that optical out, hopefully it will solve the jitter.

I haven't made any changes to USB audio. It's a common HAL across all Android devices.

Pi device specific audio HAL supports 16-bit PCM at 44100 & 48000 Hz for audio output. This also applies if you use a GPIO audio DAC.

Anyone have "Ok google" hotword working? I've installed nano Opengapps, but won't work.

You need the Google app and maybe also the Google assistant app.

I've installed and updated all google stuff, but the hotword detection won't work.

You need a microphone.

Hi, the versions 17.1 and 16.0 always reboot after loading the boot image over and over again, and never boot. In version 18.1 cannot change the time zone, the rest works fine.

• Audio DAC (using GPIO DACs e.g. Hifiberry DAC+)

I assume it does not apply to Hifiberry Digi+? Trying to get pure optical out but Digi+ does not seem to work.

I've enabled kernel drivers for all Hifiberry DACs.

If you want to use some other DAC besides Hifiberry DAC+ you need to select 'Hifiberry DAC+' from Settings -> System -> Advanced settings -> Audio device. After this edit /boot/config.txt and change dtoverlay=hifiberry-dacplus to load the driver for you DAC (i.e. change it to 'dtoverlay=hifiberry-digi' in your case).

Thanks a lot. Forgot to enable root in dev settings.
So I enabled DAC+ in Advanced settings
Changed config.txt line to dtoverlay=hifiberry-digi
Does not seem to work, it no longer plays via 3.5mm and no signal on digi. YT Music gives playback error. UAPP player is stuck on 'buffering' stage

according to https://www.hifiberry.com/docs/software/configuring-linux-3-18-x/

removal of dtparam=audio=on does not fix the issue
adding force_eeprom_read=0 causes bootloop

Instructions for some other Linux distro don't apply here.

Android audio HAL can currently open and use only one ALSA device at a time. So, that's either HDMI, 3.5mm jack, or audio DAC.

Check 'dmesg' output on booting the device that driver for your DAC is loaded and it's registered as ALSA device. My build also include ALSA tools (tinypcminfo/tinymix/etc) that you can use for this.

Is it possible to use ntfs-formatted usb-devices?

 

[KonstaT]

Is it possible to use ntfs-formatted usb-devices?

You can on LineageOS 17.

Support for NTFS drives is not included in LineageOS 18 for some reason. http://disq.us/p/2fr6xj1

Can we config the setup of vnc server?

The scroll of the vnc seems difficult from android to android.

Thanks

hmm weird i installed it on my micro sd and its crashs right when it gets to the white page with the logo ,"emergency" and "next" on the button. I tried different sd cards, redownloaded the Zip file and the same problem happens. Im running on pi 4 8 gig Ram

In the picture This appears for 2 seconds and just restarts

I'm not aware of any way you could configure it server side. You can do this on the client depending on the app your using. I only tested VNC with Remmina which comes bundled with Ubuntu and it seems to work fine with that.

General advice is to use proper sdcard (at least class 10) and power source (3A in case of Pi 4). Impossible to say what could be the issue without seeing any logs anyway.

There's also https://github.com/lineage-rpi/android_kernel_brcm_rpi/issues/6 but there's been some mixed reports whether this is fixed in Android 11 (or there's two similar separate issues).
