I have a TX5 PRO that i flashed with Armbian a while back. Yesterday i decided to upgrade to the latest focal image from this forum (was running an RC version of focal). Booting into the image worked fine, and flashing it to emmc didn't give any errors. However, now the board will not boot. Not sure if i used the 'shutdown' or 'reboot' command, but after installation finished i intended to boot from emmc, but it didn't boot at all. The light stays red, but i recall the light being blue when powered on, so it looks like it is in sleep mode. Power cycling the device does not work, and i can't find the remote (might have been thrown away). Is there any way i can force it to boot up? I've tried with the SD card inside, but still nothing. I've attached a picture with the board, does anyone notice any debugging pads that might help with booting it up?

Hi @misterzanos. Regarding your issue, you might want to look into pulseaudio's echo cancellation. I remember hearing that it does quite a lot of other things too, like noise reduction. You can also enable beanforming if your mic has more than 1 physical microphone embeded. http://forums.debian.net/viewtopic.php?f=16&t=128306 https://arunraghavan.net/2016/05/improvements-to-pulseaudios-echo-cancellation/

Leaving this here since it might help someone in the future. Moved to a raspberry pi with raspberry pi os but had the exact same problem. Guessing the issue is the same but cannot 100% confirm yet. So, i basically applied this fix: https://hackaday.io/project/165208-an-old-rotary-phone-as-bluetooth-set/log/162491-setting-up-the-bluetooth Looks like the problem is with pulseaudio not setting the proper values when communicating over bluetooth, so you need to compile your own version. ``` git clone git://anongit.freedesktop.org/pulseaudio/pulseaudio The changes need to be made on the files src/modules/bluetooth/backend-native.c and src/modules/bluetooth/backend-ofono.c from the Pulseaudio source. The line that reads *imtu = 48; has to be changed to *imtu = 60; Once this is done the Pulseaudio module can be compiled by calling sudo apt-get build-dep pulseaudio cd pulseaudio ./bootstrap.sh make sudo make install sudo ldconfig ``` Copy/Pasted the original information just in case the link changes. Hope this helps someone, i dug a few days to find that Later Edit: Finally got to testing this myself. Doesn't work, but leaving this here since it might be a push on the right track..

Hi. I am trying to connect a bluetooth speaker that also has a microphone to armbian. When using it as a plain speaker via A2DP, it works fine. However when i switch it to HSP/HFP in order to use the microphone, i get a lot of static, random crackling and very low volume on both the microphone and the speaker. Using a usb bluetooth adapter for this. I've used the same adapter + speaker on a different machine (x86 running lubuntu 19.10) and i did not have any static at all when using HSP/HFP (sound was indeed a bit lower quality that A2DP but nothing major). Also i could not get the speaker to switch to HSP/HFP with the default audio tool in armbian desktop, nor on the CLI with 'pacmd set-card-profile ...'. The only thing that worked was using 'pavucontrol'. I am running "Armbian_20.08.0_Arm-64_focal_current_5.7.0-rc7_desktop_20200531.img.xz" from balbes150's post on an x96 mini.

Hi, thanks for the reply! I was using images from here, since tx5pro is not an officially supported device: I managed to get it working in the end. The issue is that i was following outdated video tutorials for this, and the new instructions changed. To be more concrete, i was copying the device tree to the root of the sd card and renaming it, instead of changing the env file to contain the path to the proper device tree file. So i was booting with the wrong dtb file each time if anyone gets stuck on this, i followed this: https://www.ondroid.net/armbian-os-uenv-ini-and-extlinux-conf/ the folder structure is not 100% the same (dtb files are in dtb/amlogic, not in the 'dtb' folder) but similar enough.

Hi, I've tried booting into Armbian on a TX5 PRO and all i have managed up until now is to get stuck on the boot screen . Most tutorials I found are for older versions of Armbian. What i did: From here: [REMOVED LINK], i downloaded both the bionic and eoan versions, hoping a newen/older version might help. Both produced the same result. Even tried the newer RC2 version. After downloading the image, i used xzcat IMAGE | dd of=/dev/sdc to write it to a microSD card (also tried with usb stick) copied each *S905X* dtb file to the root of the same partition, and renamed them to dtb.img. None behaved any different. From the update app inside of android, i selected the JAR file inside the microsd card and pushed update. It rebooted but only showed the boot splash screen. I have managed to boot libreELEC on this machine so i know that the usb stick / microsd card are bootable. Any ideas on how to get this up and running?
