Problems with XGM_StartPlayPCM function #309

Closed saintienn closed 8 months ago

saintienn commented 8 months ago

Hello Stef!

I updated SGDK just now and some weird things happened. When I compile I get an error like "error: this method is obsolete, use SOUND_PCM_CH4" for this line: XGM_startPlayPCM(73, 10, SOUND_PCM_CH4);

But when I change SOUND_PCM_CH4 to number 4, it compiles but... When I play this several times the background sound stops.

if I change SOUND_PCM_CH4 to SOUND_PCM_CH_AUTO no sound will be played (only the background music)

I use the XGM_startPlay function for the vgms and the XGM_startPlayPCM function for the WAV effects

May be some issue related with CH1 PCM, when the background stop if I excute XGM_resumePlay(); it play again

Hello !

Are you sure you're on the last version ? because SOUND_PCM_CH4 shouldn't produce any error (Z80_DRV_CH3_SFT does). Also SOUND_PCM_CH_AUTO isn't supported by XGM driver (see the documentation of XGM_startPlayPCM(..) method). And SOUND_PCM_CH1 is normally reserved for background music so better to not use it for SFX !
