Why Does OBS Audio Delay

Audio delay issues in OBS are very annoying, but they are pretty standard; this issue happens for several reasons, like

  • Sample rate mismatch(When the sample rate, which usually stays 44.1 kHz or 48 kHz of your audio device OBS settings and output device are not exact)
  • Buffer size inconsistency(Different devices have different buffer sizes, affecting how quickly audio is processed. If the buffer size is inconsistent, then an audio delay will happen)
  • Processing overload(If your PC struggles to process the workload, then an audio delay may happen)
  • Conflicting applications( Other programs using your audio device can interfere with OBS, which causes audio delay; in such cases, we need to stop those applications temporarily)
