Xbian-update upgrade stopping I2S sound output. #805

Closed coderpop closed 8 years ago

coderpop commented 8 years ago

Every time I upgrade xbian-update package since the New Year, I2S audio output ceases after the reboot. The last xbian-update package to not do this is 20151221 (from memory).

Even tried again yesterday with the same problem. I2S tested and working, xbian-config, upgrade xbian-config, reboot, no sound...

The I2S hardware is detected and correctly reported with aplay -l and alsa is selected in kodi and the DT settings are in /boot/config.txt.....But yet there is no sound!

Only one idea I have to figure out what's your problem is:

When sounds does not work, what says lsmod | grep lirc? If the output is something like this

lirc_rpi                6106  0 
lirc_dev                7794  1 lirc_rpi
rc_core                15912  1 lirc_dev

LIRC is probably blocking I2S and then look to dmesg | grep lirc

[   14.418455] lirc_dev: IR Remote Control driver registered, major 244 
[   14.436624] lirc_rpi: module is from the staging directory, the quality is unknown, you have been warned.
[   14.439763] lirc_rpi: to_irq 188
[   15.395112] lirc_rpi: auto-detected active high receiver on GPIO pin 22
[   15.398158] platform lirc_rpi: lirc_dev: driver lirc_rpi registered at minor = 0
[   15.398187] lirc_rpi: driver registered!

In my configuration I'm using a Hifiberry Amp+ (I2S) and LIRC at the same time, but I have remapped the LIRC input pin (using GPIO 22):

...
# GPIO pins have to be remapped for LIRC for working together with Hifiberry
dtoverlay=lirc-rpi,gpio_out_pin=16,gpio_in_pin=22,debug

# Hifiberry
dtoverlay=hifiberry-amp
...

Just did all updates from stable and staging - sound is still fine :smile:

Sorry for the delay in replying, my Father has been ill.

No that is not the answer to the problem. I tried again today and with everything updated to todays latest with the exception of xbian-update and all is well. Do the upgrade to xbian-update and it stops the sound.

lsmod | grep lirc has nothing either before or after the upgrade. Alsa-base and alsa-utils are still installed and the latest. Kodi sound output still has Alsa selected for output. In /boot/config.txt the DT lirc overlay is still commented out.

lsmod | grep dac gives the following.... xbian@cinema ~ $ lsmod | grep dac snd_soc_hifiberry_dac 2154 0 snd_soc_core 120296 3 snd_soc_hifiberry_dac,snd_soc_pcm5102a,snd_soc_bcm2708_i2s snd_pcm 67774 3 snd_soc_core,snd_soc_hifiberry_dac,snd_pcm_dmaengine xbian@cinema ~ $

So.....The mystery continues! ;)

@coderpop And the module snd_bcm2835 is definitely NOT loaded? See also here http://forum.xbian.org/thread-2397-post-30868.html#pid30868

coderpop commented 8 years ago

Well, well.... That did it!

Interestingly commenting out snd_bcm2835 before the upgrade does not work. After the upgrade the commented out info is all magically back again! - But if you do the upgrade, then comment out, then reboot....It works!

Thank you for the help on this, it's been driving me nuts.

Cheers :) :+1:
