Is there any Wip on Armbian for this Board?

Tested the Hummingboard and found only 16bit supported. The Things from Solidrun are far too expensive IMO. Regards

Channel downmixing is still happening on current Kernel Versions on the H3. On the RPi i use this Card, it is connected via I2S so there aren´t any timing Problems and xruns. I was surprised by myself when i first saw this (btw when i bought this card about two years ago, this card was a mess and support on the R Pi community is it still..) I have got an Odroid C2. On Armbian there is no 8 Channel support (compiled yesterday in the morning), speaker-test gives only distorted noise, in case you choose more than 2 channnels. In the LibreElec Project on the Hardkernel Forum, they thought they had solved this Problems but they didn´t as you can see from my post. I have got a Hummingboard, that has 8 Channel Out via HDMI. Regards

There is no Multichannel Output on H3 Boards via HDMI, i have checked this months ago. All Channels are downmixed to 2 Channels playback. I am using a Raspberry Pi 1 (singlecore) for the Thing you want to do. But even with a "tweaked Kernel" the Raspberry can only do 16 bit Output. I am using Brutefir for Crossover and Roomcorrection and build the Filters with rePhase. The Raspberry Pi (1) can do 2 Channels digital Input ( via Wolfson Audio Card) and 4 Channesl Output via HDMI...USB is not recommended cause USB and Network are using the same Chip. Regards

What about the HDMI Sound drivers, is there any change,will there be a prper 8channel support?

what did you use AS I2S capture device?

It is finally up again with some"dirty" trick. To make things clear, no matter what i have tried it was impossible to mount the emmc when there was a ext4 Partition on it (even if there was a device /dev/mmcblk1p1). Using Gpt instead of msdos Label did not make any difference. The fact, that is was possible to use the Emmc with btrfs leads me to try ext3 insead of ext4, so after creating an ext3 Partition I was able to mount Emmc again. There was a Directory "Lost and Found" 193MB on it, but I could mount it. Next step was simple, I forced nand-sata-install to use ext3 instead of ext4 and Armbian is up and running again. Regards

Thanks for your patience. I will stop trying to get the EMMC back, a 20$ Machine is not worth spending so many time on it, in the end it is only another broken SD-Card . (Now I know that i can still use it with btrfs ) A Samsungs Evo is dong its job in the Slot and Firefox is running smoothly with Cache in Ram and the new Opengl feature. Regards

parted -s /dev/mmcblk1 mklabel mbr gives an error at once: ek@orangepipcplus:~$ sudo parted -s /dev/mmcblk1 mklabel mbr [sudo] password for ek: parted: invalid token: mbr Error: Expecting a disk label type.

No matter what i try here; whenever it comes to ext4, i can not mount the emmc. I have used gparted, i wrote zeros on it with dd ....what is puzzling me is the output of fsck, that is the allways the same, there is one big file and two directories on a new formatted partition ek@orangepipcplus:~$ sudo fsck.ext4 -v -f -y -c /dev/mmcblk1 e2fsck 1.43.3 (04-Sep-2016) Es wird nach defekten Blöcken gsucht (Nur-Lesen-Modus): 0.00% erledigt, 0:00 verledigt /dev/mmcblk1: Updating bad block inode.

sudo chown -R ek /mnt/emmc does the trick armbianmonitor reports Health summary: OK and cat /proc/partitions gives ek@orangepipcplus:~$ cat /proc/partitions major minor #blocks name 179 0 31260672 mmcblk0 179 1 30947040 mmcblk0p1 179 16 7634944 mmcblk1 179 48 4096 mmcblk1boot1 179 32 4096 mmcblk1boot0 Is it possible to use nand-sata-install again or do ihave to change the filessytem to ext4 somehow before ?

mkfs.btrfs -O ^extref,^skinny-metadata -f /dev/mmcblk1 works without Errors, mountint to emmc works, armbianmonitor is denied as root or user: ek@orangepipcplus:~$ armbianmonitor -c /mnt/emmc WARNING: It seems you're not testing the SD card but instead /dev/mmcblk1 (btrfs) mktemp: konnte das Verzeichnis nicht mittels Schablone „/mnt/emmc/cardtest.XXXXXX“ erstellen: Keine Berechtigung /usr/local/bin/armbianmonitor: Zeile 731: /.starttime: Keine Berechtigung ek@orangepipcplus:~$ sudo armbianmonitor -c /mnt/emmc Checking disks is not permitted as root or through sudo.

sudo mkfs.ext4 -f /dev/mmcblk1p1 leads to an error did you mean sudo mkfs.ext4 /dev/mmcblk1 instead, that is what i have used before...

I made a small test with Firefox, because Chromium is not running on 5.20 , while browsing the web, there are write accesses to disk the whole time (even while writing this)

I am willing to help, but i do not know if my Linux knowledge is sufficient. Orange Pi Pc Orange Pi +2e Odroid C2 (without emmc) Regards

Just install another terminal programm : sudo apt-get install gnome-terminal

Of course here it is: http://sprunge.us/cWPI and this message i got by trying to mount the emmc: Error mounting /dev/mmcblk1p1 at /media/ek/a6d3948d-7cb3-4110-8034-8ccb4a492abf: Command-line `mount -t "ext4" -o "uhelper=udisks2,nodev,nosuid" "/dev/mmcblk1p1" "/media/ek/a6d3948d-7cb3-4110-8034-8ccb4a492abf"' exited with non-zero exit status 32: mount: wrong fs type, bad option, bad superblock on /dev/mmcblk1p1, missing codepage or helper program, or other error

At first i like to say that this problem is not caused by Armbian. On my OpiPC+ my EMMC has became unusuable. I got a first hint to this by updating 5.17 Jessie Desktop to 5.20, that failed after downloading 135 MB of Files. I did not thought of an Error and compiled 5.20 myself, put it on SDcard and run nand-sata-install. The Script does it work without any Errors, but after power down, the Opi did not come up again. Put in the SDcard again and tried to look at the EMMC but it was not mountable. There were some Errors fixed by running fsck but next time i tried to write on the Emmc i got Errors again, in fact i tried to run nand-sata-install again after i tried to boot from Emmc again, that fails. I run fsck again and wrote a new partiton Table, next fsck-run was without errors, everything looks fine, but next time mounting Emmc gives bad Supeblocks Errors etc. again. I have used the OPi a couple of Month as Desktop replacement, that was sufficient for me, according to Powerconsumption. As Browser i used Chromium, that was stolen from Ubuntu 14.04 armhf (you only need three Files from the Ubunto repos, the Browser itself, chromium-extra-codecs and libgcrypt, but this is not working on 5.20 because of the new opengl feature.) I think writing a lot of Files to EMMC has broken it somehow, so the Opi running from EMMC is not the best for this needs, perhaps running from a Filessystem in Ram would be a better solution.( I have used PuppyLinux and Tinycore on slow x86 Machines and speed was amazing for the old desktops.) Anyway, has someone any Ideas to get the EMMc back to life? Regards

I am using Linux and Audio for over 8 years now and i do not agree with you at this point.

I got the same issue this morning (Opi PC /Jessie legacy /desktop), after a reboot (done by cutting off power) i could log in . There are several warning messages during boot process e.g. detected errors on file system. (yes, it is a samsung evo card) (BTW mpv is gone and pulseaudio is something i really do not like for audio.... )

I do not use guitarix....guess why . I have just made this test for you, for me it is was new to see Jack work in Full Duplex.

I have installed JackD and Guitarix on my OpiPC+ and it looks promissing. As Soundcard i have plugged in a cheap Behringer UCA202

Last time i checked JackD on armhf, jack was not able to run in Full-Duplex mode... Regards

this link is for the BPI-M3, but you are right, BPI-M2 does have the SPDIF on Pin 37 of Con2 as you can see here on Page 13.. Re gards

I have tried two different Toslink Transmitters (both are working on the Odroid C2) but i none of them is working on the orangepipcplus. It seems that it is not that easy to get the SPDIF Signal on another Pin. Nevertheless it was worth a try. Regards
