Sample Rate Conflicts
If you start recording/playback and the microphone’s status indicator starts flashing red continuously, this is due to the computer’s operating system requesting different sample rates for input and output at the same time. The microphone will still appear to function, but either the input or output will be garbled, so the LED is warning you of this problem.
This problem can happen in Windows 7 or Windows 8, and will happen by default in Windows 10, when playing and recording simultaneously. It happens with DirectSound, WASAPI Shared mode, WaveOut, MME, and other software that uses the Windows Default Format settings.
This will not happen in macOS or iOS, or with Windows software that uses ASIO4ALL, WASAPI Exclusive mode, WDM, or other software that sets the sample rates on its own.
To change the default sample rates in Windows 10
1. In the Windows Search bar, type “sound”, and then select Sound settings
2. Make sure the Samson device is selected in the drop-down menu and click Device Properties
3. Scroll down and click Additional device properties
4. Click the Advanced tab
5. Select a bit depth and sample rate from the drop-down menu
6. Press OK until you are back to the Sound properties window
7. Do steps 2 through 5 again, but this time for the Input device, and make sure the sample rates are the same for both input and output
Sample rates must be the same
Only the sample rate (Hz) needs to match. The bit depth can be different if needed. For example, these settings are compatible:
Output: 2 channel, 16 bit, 48000 Hz
Input: 1 channel, 24 bit, 48000 Hz
These settings are not compatible:
Output: 2 channel, 24 bit, 48000 Hz
Input: 1 channel, 24 bit, 44100 Hz
