Is there any way to update my sound card to use a more standard period size? Or am I out of luck here? That buffer size is also very... unusual. > On Mon, Sep 7, 2020 at 5:10 PM Dan Zink <sludgefree(a)gmail.com> wrote: > Hello all, > > Sometimes I want to use jackd with the laptop speakers or headphones, instead of my audio interface.
