[SOLVED] todays upgrades (16.1 and 4.4.8)

[Skywatch]

I applied todays upgrades to a pi1 and a pi2.

Both on reboot had no web interface. Also no kodi showing in top. No start-up sounds from I2S either.

Have powered off the pis and removed the sd cards for reflashing back to older version now.

Hi,

It seems that after the 4.4.8+ upgrade, Alsa is broken somehow:

Terminal

xbian@livingpi ~ $ aplay -l
aplay: device_list:268: no soundcards found...
xbian@livingpi ~ $ sudo aplay -l
aplay: device_list:268: no soundcards found...
xbian@livingpi ~ $ lsmod

snd_pcm 70156 1 snd_bcm2835
snd_timer 17617 1 snd_pcm
snd 48247 3 snd_bcm2835,snd_timer,snd_pcm
xbian@livingpi ~ $ dmesg | grep snd_bcm

As can be seen, snd_bcm2835 does get loaded but isn't visible to Alsa at all. This is highly disheartening as I had just managed to get a centralized Mopidy with snapcast clients running on all my Xbian RPi's. Now that doesn't work anymore as snapcast only sees a null sound output (there used to be about 10 different output options, related to various ALSA paths):

Terminal

root@livingpi ~ # snapclient -l
0: null
Discard all samples (playback) or generate zero samples (capture)

Any idea how this could be fixed?

One thing that worked for me in the past was to reinstall the alsa packages....sudo apt-get install alsa-base alsa-utils

It might work for you.

Do you have kodi running after the updates then?

No such luck with the alsa packages (did an apt-get install --reinstall just to make it really do something ).

Kodi is running, and even the audio works, which is somewhat of a surprise. It now has only the audio output options "Analogue", "HDMI" and "HDMI and Analogue", missing the Alsa options (i.e. falling back to the Kodi-internal RPi audio support). My verdict would be that it's Alsa that was broken in the recent update.

Oh, and the problem host is a RPi 2 (Machine model: Raspberry Pi 2 Model B Rev 1.1), if that makes a difference. I have an identical model on which I haven't yet run the update which still works (so if anybody wants any kind of debug comparison on them I can provide that).

Hmmm, that's weird

I'm running 4.4.8 kernel and 16.1 on all my systems (2x RPi1 [1], 1x RPi2 [3] and 1x RPi3 (this my test system, nearly unconfigured) [2]), absolutely no problem.

aplay -l shows sound devices, Kodi comes up and is working

[1] one using onboard sound, the other HDMI
[2] using HDMI sound
[3] using Hifiberry AMP+

@sorvakko

From which kernel version did you update? I suppose from 4.1 version

So please check if you have

Code:

dtparam=audio=on

in your /boot/config.txt

[Skywatch]

My update was from 4.4.7 (all pi here are running this).

A btrfs roll back on both pi still left it without kodi running ??? -- So that is when I took the cards and reflashed to earlier version as something is not good here (but the last 2 weeks of upgrades were fine).

I knew that

Quote:A btrfs roll back on both pi still left it without kodi running ??? -- So that is when I took the cards and reflashed to earlier version as something is not good here (but the last 2 weeks of upgrades were fine).

Unfortunately this will never affect installed kernel, because /boot partition is VFAT and is not able to have snapshots. So probably you have kernel issues (the raspberry pi guys made same changes for Dynamic DT)

I was testing kernel with all my available combinations before releasing tough.

[Skywatch]

OK, I 'll try to add the updates one at a time (not the kernel) and see how it goes then.

Aand that did it. I've been falling more and more behind on changes in the Linux kernel and had completely missed the devtree stuff. Thank you!

(and Skywatch, sorry for hijacking your thread, you seem to have a completely different issue..)

@Skywatch

While testing and switching between configuration I had one situation Kodi does not come up.

Removed Hifiberry card but did not restore settings in /boot.config and audio settings in Kodi. So no sound device was available after boot and Kodi did not came up (did not further investigation, be on skinning of config-xbmc for Krypton and won't interrupt )

Maybe you have same or similar situation

[Nachteule]

@Skywatch

Are you using hifiberry-dac overlay?

Maybe this commit could solve your issues with kernel 4.4.8

New kernel packages has been built and are available in about 4 hrs

[IriDium]

Just done an upgrade on RPi2 using "devel" (4.4.8) and everything seems to be working. System boots and all looks well. Cannot test hifiberry!

@Nachteule

Thank you for that, it works now! -

@Skywatch

Thanks for feedback
