I plugged a USB microphone into TV to record external audio. In my .NET app I can detect it with AudioManager.GetConnectedDevices(). To record audio I set the privileges (microphone) and follow the instructions here:
https://docs.tizen.org/application/dotnet/guides/multimedia/raw-audio/
I tried both methods sync and asysnc:
https://docs.tizen.org/application/dotnet/api/TizenFX/API11/api/Tizen.Multimedia.AudioCapture.html
https://docs.tizen.org/application/dotnet/api/TizenFX/API11/api/Tizen.Multimedia.AsyncAudioCapture.html
I instantiate AudioCapture or AsyncAudioCapture objects and when I invoke the Prepare() method the app crashes without any exception or error message.
Simplified code snippet:
AudioCapture audioCapture = new AudioCapture(44100, AudioChannel.Mono, AudioSampleType.S16Le); int bufferSize = audioCapture.GetBufferSize(); const int RecordingSec = 1; bufferSize *= 10 * RecordingSec; audioCapture.Prepare(); // THIS LINE CRASHES byte[] buffer = audioCapture.Read(bufferSize); The same result is on two different models (Tizen 6.0 and Tizen 6.5).
How can I record audio from microphone on Tizen TV? What am I missing?

my tizen app is working fine on tizen 4 same is not working on tizen 7
when i am trying to install the app  i am getting this:
Unable to install .please try again later .if the problem persist, reinstall the application from the install web app menu or install from usb device menu and try again.
what  will be the issue for this  as I am not able to install the app on tizen os 7

As to play the youtube video we need to use the youtube iframe, we are facing challenge here. When the youtube video plays on the TV, we lose control over app and hence next video as per CMS does not play. Same happens vice versa i.e when a video from CMS starts playing we are not able to play youtube video if it is next in the list.

Hi everyone,
I’m having trouble launching an app on Tizen 5.0 of 55'' inch. There are no error messages or logs; the app tries to start but then says it failed to open, even though it was successfully downloaded and installed. Any help would be appreciated.
find the below attached ss for reference  (details of model)

Hi, I've developed the Tizen app using the web and now after building it, the build is created in wgt format.
I want to install the build directly on Samsung Tv so that I can test the app there once.
I've already created the certificates and it's also verified by the Tizen team.
Now, when I tried to connect the SamsungTv with Tizen using the Device Manager I'm getting these following errors
The remote device is already connected by another one. This remote device is running on a non-standard port or There is no IP address, please check the physical connection What I've done?
I opened the developer mode of Samsung tv and updated the IP address with my system IP address and in the device manager I added all the details what was required and after clicking on add button then I faced the above errors.
Can anyone help me like how can we either create the build in .tmg format because Usb demo packaging tool is not supported now.  Or how can I connect the SamsungTv with Tizen Studio using the Device Manager. 
I've read and went through the documentation from official site still I face this issue.
