Hello,

I'm trying to set native resolution when viewing on my BenQ MW516 projector.

Initially it starts with 1920x1080 resolution and does not have 1280x800 in its settings.

After trying this:

Code

xrandr --newmode "1280x800_75.00"  106.50  1280 1360 1488 1696  800 803 809 838 -hsync +vsync
xrandr --addmode eDP1 "1280x800_75.00"

I can set this resolution, but the projector says the resolution it gets from pc is 1280x1024, and the optimal is 1280x800.

This trick previously worked on my other PCs, with intel or nvidia GPUs. How to make it work on this minipc?

Libreelec version is:

LibreELEC (official): 8.2.5 (Generic.x86_64)

I do not know, why it says eDP1, because the projector is connected to its VGA output.

I've got a cheap USB audio adapter and it just worked. I get stereo signal from it and it is enough for my current setup: pp_009726431322.html

lsusb says:

Thank you!

andrius · No audio on intel baytrail minipc andrius January 1, 2019 at 2:19 PM

Thanks a lot for your help! I already ordered an USB audio adapter and will try how it works. I'll post my results if I will not forget

andrius · No audio on intel baytrail minipc andrius December 28, 2018 at 5:52 PM

I also tried the Asus-T100 firmware you referenced previously - the result the same as with default firmware included in hiassoft build - after alsaucm cofinguration I get a working speaker-test, but distorted sound and unstable Kodi.

Out of curiosity, I also tried to reboot with an empty firmware file:

Code

minipc:~ # rm .config/firmware/intel/fw_sst_0f28.bin 
minipc:~ # touch .config/firmware/intel/fw_sst_0f28.bin

As a result I got dmesg with some firmware loading errors (as expected). Also, video playing was smoth - without any jumps or gui appearances.

But after stopping the movie, it froze at some moment. Maybe some kernel/OS issue?

My ideas/questions for now are these:

1) is it possible to get Kodi talk to audio port just like speaker-test does - using 16 bits?

2) maybe it will be easier to buy an USB audio adapter and make Kodi talk to it instead of baytrail audio? Is it easy to direct Kodi sound to usb? Is there a known list of (cheap) working usb sound cards?

Kind regards

Second try - with file from windows driver package: I5qudong/DriverPackage/Installer/PlatformInstaller/Drivers/audio/realtek_fw_sst.bin

speaker-test does not play anything at all - no clicks. Also, there are some errors in dmesg output. The pc probably did not like the firmware...

First try - with local fw_sst_0f28_ssp0.bin:

Same result - no music, just small "clicks".

Quote from HiassofT

An interesting test would be playing a 24bit 48kHz stereo WAV file with aplay. If there's a driver / firmware bug it should give the same (or similar) distortions as kodi.

Yes, you're right. I downloaded a sample from here: audiotestfiles.zip

I tried aplay audiotestfiles/sourceCode\sourceCode/WAV/PCM 24 bit/pcm stereo 24 bit 48kHz.wav and it sounded very quietly, way too fast and without any stereo effect.

An additional problem with Kodi is if I do not stop it after booting libreelec, it makes the system freeze - the picture on the screen stays static as it was before the freeze, mouse pointer does not move, ssh on port 22 not responding. Can it happen because of audio fw/driver issues?

I'll try with different firmware files and will post the results here.

I downloaded bluetooth firmware from here: Index of /sources/linux-firmware/rtl_bt

Now I do not have FW loading errors in dmesg.

But KODI is not playing anything nicely.

Hello,

today I tried another one headphone and it seems, that speaker-test now works as expected (after putting alsaucm config into autostart.sh). The other headphones probably had some problems with correct contacts...

But Kodi on this Hiassoft build spoils the sound - after systemctl start kodi the earphones start getting white noise. Also, kodi seems unstable - it struggles to play movies and music. It plays music too fast and very very quietly, it jumps a second here and there, it loops movies unexpectedly. Is there any way to use the kernel with firmware loading from the build like this, but take the kodi from a more stable branch?

Andrius

andrius · No audio on intel baytrail minipc andrius December 22, 2018 at 8:39 AM

Before getting any sound I should do:

Code

alsaucm -n -b - <<EOM
open bytcr-rt5640
reset
set _verb HiFi
set _enadev Headphones
EOM

Out of curiosity: what do these "beeps" sound like? speaker-test -t sine should output a 440Hz sine alternating on left and right channels.

By seeing 'sine' I thought it should make some varying pitch sound. Only after a while I remembered any sound is some kind of sine

Those beeps are fixed-pitch sounds in both ears at the same time. If I set -c 1 then it plays same beeps in both ears, just quieter.

I also tested with some mono wav from internet:

http://www.mauvecloud.net/sounds/pcm1644m.wav

This plays it loud: speaker-test -c 2 -r 44100 -t wav -w /storage/pcm1644m.wav

This plays it quiet: speaker-test -c 1 -r 44100 -t wav -w /storage/pcm1644m.wav

The sound is correct (laugh), just on both ears instead of one.

Also, when I try to play something with kodi, the sound output gets some garbage - some high-pitched distortion of the original sound.

I did not try any alternative firmware. Maybe I'll find some time later today.

andrius · No audio on intel baytrail minipc andrius December 19, 2018 at 8:12 PM

"Speaker" does not produce any sound on my headphones.

"Headphones" always makes beeps in both ears at the same time, even though the speaker-test says "0 - Front Left" or "1 - Front Right".

Movie playing in Kodi just makes some strange noise.

But the beeps are definitely a big progress when comparing with the complete silence

Any ideas - what can I try now?

Vielen Dank Matthias!

andrius · No audio on intel baytrail minipc andrius December 19, 2018 at 8:01 PM

Yes, this seemingly works somehow with Headphones value. speaker-test is just producing beeps in both ears. Shouldn't it make some sines?

I'll test Speaker and some movie with kodi.

_enadev and _disdev give me some errors.

I'll try to read some docs about them.

How do I install it? Usually I put the img file into /storage/.updates

The tar file you sent is not an img. I guess /target directory contains the image files, but how do I install them?

andrius · No audio on intel baytrail minipc andrius December 17, 2018 at 8:10 AM

I unzipped the windows driver package I got for this device. The directory /DriverPackage/Installer/PlatformInstaller/Drivers/audio/ contains the following files:

isstrtc.cat

isstrtc.inf

isstrtc.sys

realtek_fw_sst.bin

rtii2sac.cat

rtii2sac.inf

RTII2SAC.sys

Maybe this realtek_fw_sst.bin can useful?
