We’ve been streaming our church services with OBS using a stereo signal from our sound board (Yamaha O1V96) into the PC’s microphone input (through an attenuation cable to get the right signal level). When someone views our stream from a PC or when they use earphones/earbuds on their phone the sound is fine. But if they listen using their phone’s built-in speaker, then it’s virtually inaudible (way too soft). I have no idea what is going on, so any help would be greatly appreciated.
(I’m terribly new at this. We have recently started streaming our church services, first simply with my phone now using OBS and “better” equipment. When my phone was doing it all using its built-in condenser mic, it seemed to work fine. Now that we’re using OBS and an audio signal via cable to the PC it only works when played back on stereo speakers or headset, but not on a phone’s single speaker.)
