Playback is stuttering (e.g. TTS).

In setups with many connectors, devices, channels, or high sampling rates, performance issues can lead to stuttering. First, check whether other processes with a high CPU load may be the issue. Next, try the following

  • Reduce resampling by configuring connectors to use the device sampling rate OR change the physical device sampling rate to match the connector’s rate.
  • A 1:1 channel mapping reduces the required channel multiplexing.
  • Enable buffering on the logical device level (TBD) at the cost of response time.
  • If you have implemented your own connectors, try to “pre-compute” audio data if possible.
