Sound_Enable
(SWI &40141)
| Entry | |

| Exit | |
|---|---|
| R0 | Previous state (1=disabled, 2=enabled) |
Use
This SWI is used to enable or disable sound output. It can also be used to read the state of the sound system.
Notes
When sound output is disabled, sound interrupts will cease, and any processing which is tied to them (for example the sound scheduler) will effectively pause.
Service_Sound 9 or Service_Sound 10 will be issued if sound output stops or starts as a result of this call.
