  1. another question. Which kernel topics are treated with the Armbian version? Does the Armbian version number say a kernel basic configuration? or what is being treated here? I'm just at the exclude which modification has caused the problem. possible plausible points for me: 1) Armbian Version 2) Kernel Version; Kernel configuration 3) ALSA - Version (ALSA configuration is always the same) 4) Ubuntu Version THX
  2. is there anywhere in GIT or on the Armbian webside Changelog & Known Issues to the change of any image? i need the changes to version Armbian 5.31 - 4.4.73-rockchip so that I can continue my research and solve the problem. THX
  3. I have a usb sound card connected: Behringer U-Control UCA202 what do you mean by cpu governor ? can I change something? How do I find out what that is?
  4. I have already played around a lot wirh https://github.com/armbian/build and unfortunately i have still the audio problem. my problem: crackling and bad sound with this command: (Play my line-in a USB sound card to the same output of this USB sound card) arecord -f S16_LE -c2 -r44100 -d 0 -D plug:dsnoop01 | aplay -B 1 -D plug:LineIn01 Look also this Post: I do not have the problem with this Armbian Image: 4.4.112-rockchip 4.4.73-rockchip with these kernel/image I have the problem: TinkerOS: 4.4.71+ (latest) Volumio: (latest image ... do not remember exactly ...) Armbian: 4.13.10-rt3-rockchip, 4.14.18, 4.14.15, customize 4.14.14, latest /default/next/dev, (I did not take all the notes but it was at least 10 images) I have now found out that the Alsa plugin dsnoop makes problems. even if I have the same version of Alsa from the working kernels (see above) root@innotune:~# aplay --version aplay: version 1.1.0 by Jaroslav Kysela <perex@perex.cz> With this command I have an excellent recording even with the non-functioning images (see above): arecord -f S16_LE -c2 -r44100 -d 0 -D plug:hw1,0 -t wav /root/test101.wav Now your expertise is needed because I do not know any further: which settings on the kernel caused this problem? or is the problem with alsa? do you have a tip what I can still try? Many THX EDIT: problem synonymous with pulseaudio - crackling and bad sound with this command: pacat -r --latency-msec=1 -d alsa_input.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00.analog-stereo | pacat -p --latency-msec=1 -d alsa_output.usb-Burr-Brown_from_TI_USB_Audio_CODEC-00.analog-stereo
  5. https://docs.armbian.com/Developer-Guide_User-Configurations/ I have read the instructions but i get error at the compiling process. My approach was like this: I copied the patch to -> build/userpatches/kernel/rockchip-next/ then I started ./compile.sh and chose in the selection dialog with the blue background? next (Kernel) however, many error messages followed the compilation will be aborted. in which folder do I have to copy the most recent RT patch for 4.4.115 ? and which files do I need here anyway? which image should I select in the selection dialog with the blue background? default or next or dev Unfortunately, I can not find the file "linux-rockchip-default.config" in the userpatches directory. Many THX
  6. hy, I have already created some kernel versions with this tool: https://github.com/armbian/build However, I have big problems with the audio latency of different kernel versions. Look at this post: the only kernel that worked from the beginning is "ARMBIAN 5.31 stable Ubuntu 16.04.3 LTS 4.4.73-rockchip" 1) I would now continue to use these but I have to make some adjustments. Then I want to recompile this kernel. is it possible to recompile the .confiog file (see attachment)? 2) With the GIT Reop, I can only make changes to the new kernel versions is that correct? Many THX .config
  7. hy, now i start the ./compile.sh script in my VMware with Ubuntu Xenial 16.04 x64 run. the menu opens, I enter: "u-boot and kernel packages" "show a Kernel conf......." I choose "thinkerboard" and then "default" or "next" or "dev" it does not matter what I choose it comes then always the message: [ o.k. ] Downloading sources [ o.k. ] Checking git sources [ u-boot v2017.09 ] fatal: read error: Connection reset by peer fatal: read error: Connection reset by peer [ .... ] Fetching updates fatal: read error: Connection reset by peer [ .... ] Checking out error: pathspec 'FETCH_HEAD' did not match any file(s) known to git.

  8. okay THX is there an instruction how to do that? Kernel Compiling is new territory for me. I've been reading a lot and I'm not getting anywhere. is there a howdo special for the thinkerboard? what should I enter in the command line so that all required files are generated?
  9. hy TonyMac32, you mean I should run on an external computer with x64? how do i get the newly created build from my x64 then on my thinkerboard? thx in the config file under /root/config-4.4.102-rockchip there is an entry CONFIG_DRM_DW_HDMI_I2S_AUDIO = y CONFIG_SND_SOC_HDMI_CODEC = y I wanted to comment out and recompile it. is possible? if so, how is the command in the console that the files under dtb-4.4.102-rockchip be recreated. ?
  10. Hy Igor, THX for your helb but i have a Tinkerboard current kernel: ARMBIAN 5.36 user-built Ubuntu 16.04.3 LTS 4.4.102-rockchip this build https://github.com/armbian/build. is only for x64 root@piotre:~/build# ./compile.sh [ o.k. ] Using config file [ config-default.conf ] [ o.k. ] This script will try to update Already up-to-date.

  11. Hy, I miss a few options in the kernel current kernel: ARMBIAN 5.36 user-built Ubuntu 16.04.3 LTS 4.4.102-rockchip Thinkerboard I still need: 1) - disable HDMI audio so that it will no longer be displayed as a sound card under "aplay -l" deactivate "card 3: rockchipminiarm" same as with the image kernel update of Igor root@se:~# aplay -l **** List of PLAYBACK Hardware Devices **** card 0: Audio [USB Audio], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: Audio [USB Audio], device 1: USB Audio [USB Audio #1] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: Audio [USB Audio], device 2: USB Audio [USB Audio #2] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: CODEC [USB Audio CODEC], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 card 2: CODEC_1 [USB AUDIO CODEC], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 card 3: rockchipminiarm [rockchip,miniarm-codec], device 0: ff890000.i2s-i2s-hif i i2s-hifi-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 root@se:~# 2) options in ALSA -> Dummy (/dev/null) soundcard -> Generic loopback driver (PCM) 3) cifs-utils so I can access data from my NAS. Editing a kernel is new territory for me. I have already read a bit here http://www.informit.com/articles/article.aspx?p=1647051&seqNum=5 but somehow I can not apply the whole thing to the armian image. I ask for help. THX
  12. hy Igor, thanks for your information. Yesterday I switched to a RT kernel according to your instructions. My Thinkerboard work as a LogitechMediaServer with more then one squeezelite instance, librespot, MPD, shairplay, etc. it works! however, one thing does not work anymore the playback of my line input. it overrides and emits a very damaged sound. this command worked fine with kernel 4.4.73-rockchip: arecord -f S16_LE -c2 -r44100 -d 0 -D plug:dsnoop01 | aplay -B 1 -D plug:LineIn01 I also tried csound but here I have the same problem. my Kernel version now: 4.13.10-rt3-rockchip ask for info what could be the problem here and how I can solve it. THX
