thank you very much for your question. My name is***** am a computer expert since 17 years and I will be assisting you today.
Can you please let me know if you do not have any audio in your whole Windows (I suppose you use Windows, is that correct?) or just in a specific application? Has the audio been working fine before? Do you use a internal soundcard or a external one and are your speakers connected just fine to your computer?
Thanks for your patience and best regards,
