Rocking The Rocking Raspberry Pi Challenge.. Part 8 Problems I am Facing With Wolfson Audio Card...

saurocksall

Hi Guys, Sorry for the delay My exams are going on currently, so I was busy in them and had no time to write the blog, however I took time to work on the project,

In this post I will discuss about some problems I am facing with the Wolfson Audio Card.. If any one out there can help me please help me out..

 

So Here it goes..

 

First I tried to download the Image file provided by  Wolfson, it took around 15 hours to download, and after I unzipped the file size was bigger than the size of my memory card, I was depressed and angry because of this, So I searched and searched the internet for a solution for this and found ragnar.jensen's Image file which was smaller and I downloaded and installed on my card..

 

After which I am facing these problems :


1). Raspberry pi hangs allot, and gets over heated..


2).Wi-Pi and other USB devices don't work properly, works for some time and then stops completely and then system freezes..


3). When I remove and replace any USB device, Raspberry pi gets restarted, this is strange !!!


4). VLC Media player hangs allot, and shows error in audio output..


5). And the most interesting one is now I can't even get audio output form the Pi's audio jack !!!


The competition is near its end and I am now really far behind because of Wolfson Audio card, I am not a software person, but know the basic stuff, But unlike the PiFace CAD Wolfson Audio card has almost no support and tutorials etc. for making it easy to use, I agree that it is a fine piece of hardware but if it not easy to use its not worth any thing, the Element14 team should really need to focus on to provide some good documentation on how to use it, with some good examples like the PiFace People made, Something like that will be really helpful, and please make a smaller image file for it, or better make it install-able by apt-get or something..


If some one has the solutions to my problems please help me out, I will be really thank full to you guys...

  • Hi Saurabh,

     

    Sorry to hear that. Because these problems seem to be quite diverse, I'm wondering if they are power supply related. It might be good to remove all USB bits and the Wolfson card, and just try to power up the RPI alone, and make sure it is stable (try checking the uptime occasionally, to make sure it has not rebooted). If it is not stable, try replacing the PSU and/or the USB cable.

    It could be an SD card issue, or flaky connector(s) I suppose : ( hard to say. The most you can do there is visual inspection, see if it only occurs if the card or connector is lightly moved.

    A lot more tips are at here.

    Also, I'm sure Ragnar's file is ok, but _just in case_ your hardware is subtly different and the official RPI image perhaps takes that into account, it may be worth re-trying with an official image. It's a long shot.

    Hi Shabaz,

     

    Thanks for the suggestions, I checked the power supply it is working fine, I even tried a different supply which is my Nokia 5 volt 1300 mA charger still the same problem was there.

    The card I was using was the same NOOBS 8 GB cerd supplied by Element14 for the challenge, however I flashed a new card of same type bur still no successes...

     

    Then I removed the Wolfson Audio card and its all working now, but still the VLC media player is lagging and is unable to play videos, as soon as I try to play a video the VLC media player crashes..

     

    Do you know any solutions to this ?? Please respond ASAP I have only a few days left...
