Thanks for your suggestion ChrisP but apparently the only audio parameters i could find
audio.outp ...

I had the same problem and fixed it, but you must compile Android.
The reason for the problem is the screen setting resolution, the bpi thinks for higher resolution only AUDIO_HDMI makes you lucky, so AUDIO_CODEC is only temporally.

The only way I found is my way, please look here, #59:

Here I describe what to do to switch codec or hdmi as default.

As onother option, maybe it's inside the preinstalled apps SettingProvider.

You can edit it using a tool to edit apk file (I use APK Studio from here: ) and search a file named defaults.xml and check if a line is defined with:
<string name="def_audio_output_channel" translatable="false">AUDIO_HDMI</string>

Changing this to AUDIO_CODEC may also fix it.

when i try to watch a video placed in a network share, shows a message of error. but if i search on my LAN using File Commander for exemple, and chose kodi to reproduce the video, it works fine.
i dont get it

ChrisP @ liab, thx for your replies.
I would have liked to find out if the defaults.xml really is responsible for my problem as ChrisP assumed but as I didn't know how to extract the settingsprovider.apk and read in this thread that i quite likely would need a linux environment or a vm which i don't have i aborted this plan at the very beginning.
Then I gave the image provided by you, liab, before you edited your post, a try and this image is all i ever dreamed of for my BPi ! It uses analog audio output as default, I installed Kodi and could get it starting automatically with Startup Manager (Free), and even my WIFI adapter which is a Edimax EW-7811Un with RTL8188CUS chipset that does not work with any other image works flawlessly with this one!
So finally i can use the BPi as i want it to and therefore can't thank you enough. I am not sure why you removed the link to your image but as there quite likely are more users with this WIFI adapter i think they would be as grateful as i am if you released your image.

Hi anton,
I needed the space in my dropbox. But now it's up again, but without warranty how long. How I wrote in this forum a null file in system (the folder where the build.prop is) with the name audio_hdmi and AUDIO_HDMI is default. To change it again rename audio_hdmi to audio_codec.

Are you sure your wifi has a RTL8188CUS? ... -cu.img.tar.gz?dl=0

thx for reupping it.

If someone has a wish for WLAN-Stick's I think I can compile it for the following Chips too:

You need for another WLAN-Stick no complete image, only the file build for that Stick.
Outside Realtek Chips it is not possible, the supplicant will not match.

tried your image was happy that my Edimax EW-7811Un  worked my favorite image I use so far is the matrix 3.0 image I updated kodi myself and renamed the link file that ran the outside player since I like the built in one for now..  but the only thing that did not work for me with your image is the hdmi audio....  my question is how would I get the Edimax EW-7811Un working in my current in use matrix image that I am using... hopefully it is some easy feat ;)

Hi liab,

should I be able to get sound out via audio jack if I use  the BPi without any HDMI connection?
I have tried it several times with connection to my TV and without.
If the HDMI cable is disconnected I don't get any sound. If it is connected everything is fine.

@ mcray
When I stream with my image a TV stream and cut the HDMI cable at the BPI the sound on the audio jack remains on, only a little bit quiter.  You can try other "Display output mode". Using PAL or VGA there is sound generally on audio jack, even after restart. But atttention you must connect a monitor to operate it!

Your way is:
Using my image and make in the folder where the build.prop is a null file with the name audio_hdmi and restart and now HDMI sound is default. To go back to AUDIO_CODEC as default rename the file to audio_codec. Have a look to /etc/mkshrc.

The 2. way you use in your image my

Please could somone with Edimax Stick (only when it runs) post this:
