H100: Initialization of the FM radio

[fml2]

Hello,

I asked this yesterday in IRC but got no reply. Maybe here more eyes will see it.

Does the FM radio need a special initialization? I tried to set up FM screen after startup by calling radio_screen() in tree.c (where auto resume is checked). The FM screen shows up but there's no sound. I use iriver H1xx.

I saw that in the menu, the radio is also activated by calling radio_screen(). But that doesn't work right after start up. Any ideas?

Thanks!

Could it be that the audio setup is deferred nowadays, and you call radio_screen() before the audio init is done?

Yes, that's what I think. But I wasn't sure since I don't know RockBox well. Do you mean that after switching on some activities (audio setup) are completed in the background by a special thread? Or is a check ('has audio been initialized') made just before activating playback? Because auto resume is called without anything special being done before.

Yes, some init stuff is being done in the background. Don't know the details, sorry...

Thanks for the confirmation. I'll try to dig into it then. Maybe a sleep for a second or two will help thus allowing the background thread to finish its work. He-he... Poor man's solution :-)

Hey, that did indeed help!
