 Ctronome is a very-very simple programmable metronome for Linux console,

 ## Running on Non-OSS Sound Systems
-On modern Linux distributions it is not very likely that native OSS is used.
-In this case the following error is displayed when running ctronome:
-```bash
-FATAL: cannot open dsp device /dev/dsp
-/dev/dsp: No such file or directory
-```
+Currently supported sound systems are OSS and PulseAudio.
+OSS support can be provided through compatibility utilities.
 
 ### PulseAudio
+*Note: PulseAudio is now natively supported if Ctronome is compiled with it.*
+
 PulseAudio has an OSS compatibility module that can be installed to provide
 OSS support. For example on Ubuntu systems, the package is called `pulseaudio-utils`.
