From ea58b9a404d4cf39a3bb314804f42b213eb6d896 Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Thu, 15 Dec 2022 16:50:39 -0800 Subject: cmd: allow sound command to play multiple sounds Currently the sound command accepts only one value each for duration and frequency. Allowing more duration and frequency arguments enables playing a tune.
