Converting PCM Byte Data to WAV stream with proper RIFF header - NAudio

pretty new to audio stuff I'm trying to convert PCM byte data to a WAV stream that has a RIFF header using NAudio. Right now, I'm doing this

            using var stream = new MemoryStream(args.PcmData.ToArray());
            await using var sourceWaveStream = new RawSourceWaveStream(stream, new WaveFormat(8000, 1));
            
            sourceWaveStream.Position = 0;
            
            await foreach (var result in _whisperProcessor.ProcessAsync(sourceWaveStream))
            {
                Console.WriteLine(result.Text);
            }

            using var stream = new MemoryStream(args.PcmData.ToArray());
            await using var sourceWaveStream = new RawSourceWaveStream(stream, new WaveFormat(8000, 1));
            
            sourceWaveStream.Position = 0;
            
            await foreach (var result in _whisperProcessor.ProcessAsync(sourceWaveStream))
            {
                Console.WriteLine(result.Text);
            }

but im getting this error:
