I did extensive testing on HEVC video files (mostly mkv format) since last couple of builds and found the RPi2 couldn't handle mkv files with 'Attachments' properly. Only audio but no video output, the screen stays with the file selection menu. Status on lower left corner shows that it's playing (Play icon and timer ticks).

I'm also new to this 'attachments' feature of mkv, usually are one or more jpg files embedded in the file. It doesn't cause any trouble in the Kodi ARM version (test it on my tablet). Once the attachment was removed using mkvmerge, it plays without any problem.

Hi,
sorry - i have no sound on my first PI2 with my ALSA (bmc2835) Card after update to #0524.
Before #519 there was no Problem.

My second PI2 on HDMI have no Problems with sound (Video/mp3/DTS)

Is #0524 the first build when the problem starts or does this just happen to be the build you updated to from #0519? What about the builds between #0519 and #0524, which is the first build with this problem? Identify the exact build and it will help narrow things down...

Shame on me - i have not tested between #0519 and #0524.

I have now switched back to #519 (last known good build for me) and my hifiberry DAC works fine.

btw - i have other things seen - on "mtv.de addon" - would "play from here" always the first song from the list apears without Audio (only over HDMI)

Thanks Milhouse

Tested: #522 works with hifiberry DAC - #523c and #524 not.

Thanks, there's a couple of obvious candidates added to to the kernel in #0523c, can you upload "dmesg | pastebinit" and "vcdbg log msg 2>&1| pastebinit" from #0523c.

Can you try creating a file
/storage/.config/modprobe.d/disable-snd-bcm2835.conf
containing:

Code:
blacklist snd-bcm2835

Could you provide a sample file that has an attachment?

Something strange seems to be going on with ALSA device enumeration.

Since the audio DT overlay change in the kernel snd-bcm2835 is loaded by default. If you enable an additional I2S soundcard both are reported by aplay -L but kodi only lists the first device (snd-bcm2835).

BTW: an easy way to reproduce this is to add dtoverlay=rpi-dac to config.txt, this driver will load fine even without hardware attached.

Kodi log from 0523c build: http://sprunge.us/cDVV and aplay -L output:

Code:
null

    Discard all samples (playback) or generate zero samples (capture)

default:CARD=ALSA

    bcm2835 ALSA, bcm2835 ALSA

    Default Audio Device

sysdefault:CARD=ALSA

    bcm2835 ALSA, bcm2835 ALSA

    Default Audio Device

default:CARD=sndrpirpidac

    snd_rpi_rpi_dac,

    Default Audio Device

sysdefault:CARD=sndrpirpidac

    snd_rpi_rpi_dac,

    Default Audio Device

If we blacklist snd-bcm2835 only one device is reported, both by aplay and kodi and everything's fine. But if we then manually load snd-bcm2835, resulting in swapped device order, kodi again only reports the first device (rpi-dac in this case).

kodi log: http://sprunge.us/VdJh and aplay -L output:

Code:
null

    Discard all samples (playback) or generate zero samples (capture)

default:CARD=sndrpirpidac

    snd_rpi_rpi_dac,

    Default Audio Device

sysdefault:CARD=sndrpirpidac

    snd_rpi_rpi_dac,

    Default Audio Device

default:CARD=ALSA

    bcm2835 ALSA, bcm2835 ALSA

    Default Audio Device

sysdefault:CARD=ALSA

    bcm2835 ALSA, bcm2835 ALSA

    Default Audio Device

Now, if I plug in a USB dac kodi reports the first "onboard" device (rpi-dac) plus the USB device(s) but not snd-bcm2835.

kodi log: http://sprunge.us/GAHO and aplay -L output:

Code:
null

    Discard all samples (playback) or generate zero samples (capture)

Very strange...

so long,

I have created this new file directly on my SDcard with "Dataimanager-add a new file" and over ssh "nano" write *blacklist snd-bcm2835* (i am crazy lol)

#0523c -> HifiBerry works
#0524 -> also no Problem with DAC

Please by so kindly and "build in"
in the future Testbuilds ;-)

Thanks popcornmix

@ Milhouse
i think there is now no necessity ?

Quote:...can you upload "dmesg | pastebinit" and "vcdbg log msg 2>&1| pastebinit" from #0523c.

....because i've trouble to do this :-(

Here is the sample https://drive.google.com/file/d/0B9_XmyO...sp=sharing
OE 5.0.8 and 5.95.1 play this interlace absolutely smooth (with omx). Last few testbuilds playing with jerks.

https://drive.google.com/file/d/0B9_XmyO...sp=sharing
The same story. Now with a progressive video.
OE 5.95.1 - no problem

Same with HiFiBerry digi.

What do I have to add in order to make it work ? For now I'm back to #522.

Thanks.

i think:
Can you try creating a file
/storage/.config/modprobe.d/disable-snd-bcm2835.conf

This file You can create directly on your Pi

containing:

blacklist snd-bcm2835 (Popcornmix posted)

login over ssh (Putty) and: nano /storage/.config/modprobe.d/disable-snd-bcm2835.conf

then write: blacklist snd-bcm2835
strg O
str X

thats all - reboot and yout hifiberry works

....or read the 3-4 posts over yours ;-)
