Async execution should help us avoiding potential deadlock and illegal locking while sleeping in various mixer -> usb calls. To enable it, use hint.uaudio.%d.async="1" or sysctl dev.uaudio.%d.async=1. Default is disable, to remain compatible with old behaviour (with slight risk of potential deadlock). END
