I am developing a music application and have a slider set to seek through the audio file with mediaSourceAudioInputNode.Seek(). When seeking through Mp3 files, I have not encountered this problem, but when seeking through some Flac or Ogg files, the seek may work properly a few to several times, then the seek method will freeze for a few seconds and the AudioGraph will stop playback and not be able to play that file again (though it can switch to another file). I can provide specific problematic files if necessary. I have tested and gotten this problem on two Windows 10 machines.

If do not include private data, you can provide the music file in question so that we can analyze your problem.

2020-04-20T06:56:59.817+00:00 Hello, I hope you don't mind me using MEGA as I uploaded my project there. A few notes, I may have been mistaken about the .ogg files as I was unable to reproduce the error with .ogg files, but I still got the error with the provided .flac files. With the mega link, you can download the project folder as well as the problematic files and choose those files with the file picker when running the application. Once you pick the file, click the "Play File" button and the slider will correspond to the position of the audio input node. clicking a position on the slider will attempt to seek to that position in the file and this is where the error occurs. You may have to click a few - several times for the error to occur.
Here is the link: https://mega.nz/folder/SmRnwQgS#y14mCzDgmRudy6iyahl2Rg

2020-05-05T08:12:52.703+00:00 Hello, I have received a response from the team, but there are a few things we want to confirm with you: you seem to be building a music application. In this question, the
MediaPlayerrelated API is a better choice. After testing, Playing the flac audio inMediaPlayerElementwill not cause the problem you mentioned. Can you explain why you useAudioGraphinstead ofMediaPlayer? -

2020-05-09T00:34:24.35+00:00 No problem and thank you. Yes, I am building a music application, but I would like access to the features that the AudioGraph API provides such as audio effects and access to the audio frequency information so I can make an audio visualizer.
