Which audio output do you use? There is a bug in analog output - it says that it supports audio formats which in reality it can't, namely 24 bit audio. If you patch it (check this and this patch), sound output should work normally.
Building Kodi from Source was not the Thing I wanted to do. (In fact i am to dumb to patch sources... ) I have installed Kodi 16.1 from Jessie Backports out of the Repos on Top of Armbian Desktop. So at first I wanted to check if Kodi is broken somehow. It is not, it is working with USB Soundcards. So the Problem is that the Soundcards can not play S24_LE Soundformat. I don´t know if this is really a Kernel or Driver Problem because "
speaker-test -D hw:0 -c2 --format S24_LE
" returns an Error Message at once: (where hw:0 is the anlog Output)
speaker-test 1.0.28
Format S24_LE is not supported...
So if that is the Problem, there should be a simple Hotfix by editing the .asoundrc and lock the Soundformat to a supported one, i have choosen S32_LE in my Example
At first i have deleted asound.conf
sudo rm /etc/asound.conf
Next is looking for the enumeration of the Soundcards:
pi@orangepipc:~$ cat /proc/asound/cards
0 [audiocodec ]: audiocodec - audiocodec
audiocodec
1 [snddaudio ]: snddaudio - snddaudio
snddaudio
2 [sndhdmi ]: sndhdmi - sndhdmi
sndhdmi
So in my case 0 is the anlog Out, 1 I2S Audio, 2 HDMI. so an easy first shot .asoundrc file is this (for using HDMI ; card 2 if you want to choose another Output change the Number of card 2 to the desired one...) :
pcm.snd_card {
type hw
card 2
device 0
}
ctl.snd_card {
type hw
card 2
device 0
}
pcm.dmixer {
type dmix
ipc_key 1024
ipc_perm 0666
slave.pcm "snd_card"
slave {
period_time 0
period_size 1024
buffer_size 4096
rate 44100
format S32_LE
channels 2
}
bindings {
0 0
1 1
}
}
you can create this file with
nano .asoundrc
and paste the Things above. The .asoundrc file is stored in your Home Directory. Now it is possible to choose sndhdmi as Audio out in Kodi.
