[TESTING] Improved LPCM output for Vero 4K


#43

Interesting, thanks. With a 5.0 flac, @JimKnopf got 3/2.1 on his AVR. Can you try a 5.0 flac, please, and remind us what AVR you have?

A clip from that Sense & Sensibility file would be useful as well for further testing.

No. Were you expecting any GUI changes?


#44

I don’t have any 5.0 Flac files. My AVR is a Marantz NR1603.
Easy to snip out a chapter for you, where should I post it?


#45

Try https://github.com/sfiera/flac-test-files

Dropbox or similar? Have mercy on my ‘broadband’, a 15sec clip will do!


#46

Can you confirm when downloaded and I’ll remove.


#47

Got it thanks.


#48

Just tried a 5.0 FLAC and my AVR thinks it’s getting 7.1.


#49

All is good, same behavior like on my AVR. I did a mistake when posting in internal chat among the mods.


#51

Tried the upgrade to the test kernel… Put the line into the sources.list (and saved with ctrl+x and y), ran the command - everything like always - , but it outputs only this:

0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

And after the reboot the kernel version is still: Linux osmc 3.14.29-51-osmc… What’s happening here? :see_no_evil:
Any ideas how to force the upgrade to the test kernel - as the sudo apt-get update && sudo apt-get dist-upgrade && reboot with deb http://apt.osmc.tv stretch-devel main added to /etc/apt/sources.list doesn’t seem to work here for some reason?


#52

I saw something like this when I updated this morning ahead of testing the 5.0 file I referred to earlier.


#53

Which kernel version is shown when you run uname -a?

I get Linux osmc 3.14.29-51-osmc #1 SMP Tue Jan 2 09:35:33 UTC 2018 aarch64 GNU/Linux

Short log: https://paste.osmc.tv/jokayuwiyo


#54

Linux osmc 3.14.29-57-osmc #1 SMP Wed Feb 14 23:32:25 UTC 2018 aarch64 GNU/Linux

So given the date I gues no update has been applied, hence no extension of audio channel layouts via PCM.


#55

though perhaps that’s a build date, not an install date, so I need to defer to others to interpret this.


#56

That’s the kernel version. Wed Feb 14 23:32:25 is the release date and time. 3.14.29-51 would be the current stable version, released on Tue Jan 2 09:35:33.

Tried a manual reinstall of 3.14.29-57 now. It seems 3.14.29-57 was correctly installed before (I seem to have left the devel source in my sources.list) and had it downgraded to 3.14.29-51 when deleting the line and running sudo apt-get update && sudo apt-get dist-upgrade && reboot again… I don’t know. A bit of confusion here. :roll_eyes:

sudo apt-get install --reinstall vero364-image-3.14.29-57-osmc did the trick. I’m on Linux osmc 3.14.29-57-osmc #1 SMP Wed Feb 14 23:32:25 UTC 2018 aarch64 GNU/Linux now :+1:t2:

Will begin testing shortly…


#57

WAIT! I think there’s something missing in the build in stretch-devel. I can get it working properly with flac 5.0 and the Sense & Sensibility clip using a mediacenter deb @sam_nazarko sent me but it looks like the published version is different in some way.


#58

Ok :astonished: Let us know, as soon as there’re news. Or can you maybe send us that mediacenter deb, you got from Sam?


#59

Let’s let Sam check it so everyone is testing the same thing.


#60

Which kernel version and mediacenter version are you running which gave you somewhat different 5.0 FLAC test results than others here?


#61

It’s in internal version package which was not published at all. With current

vero3 kernel 3.14.29-57
mediacenter 17.6.0-25

you only have the first patch available which maps 5.1 channel audio to PCM 5.1 or better 3/2.1.
Sorry folks for this confusion, the developers have to fiddle out what went wrong when the actual development stretch was published. Please, wait for news.


#62

Eagerly waiting :slightly_smiling_face:


#63

There is no updated kernel as part of this testing; but you may receive one from other improvements made in the staging repository.

It looks like I forgot to bump the version properly. I’ve done this now and kicked off a build, so the improvements should be available shortly in 30-45 minutes.
