I see 4: 2 for scan and 2 for moving 1 station, right?
Yes, on most devices I think, unplugging the headset switches the audio to speaker and re-plugging switches it back automatically. This was an unexpected feature (on CM anyway) by default that I thought might be a good feature.
I'm not aware of any way to disable this automatic switching to speaker, but I should be able to add code that detects this situation, and if so configured, mutes the output. If anyone else would like to see this feature please let me know. I've accidentally unplugged my earphones and heard a blast of noise from my pocket. I presume that some might like this feature to avoid making unexpected noise where quiet is required ?
I'm surprised that so many people bring up the antenna-less operation, and I'd guess that also means that many people are using the speaker mode.
Some radio apps won't open if there isn't a headset plugged, maybe you could put an option in the settings that allow to enter or not the app even without nothing in the jack. Or a disclaimer before starting the audio: "no headset plugged, loud white noise ahead, wanna go on and get some?" Y / N
tried the antenna-less 'cause i read it in the thread
I should mention that in the last release or two, selecting speaker mode automatically switches the radio to Monophonic. This is based on the assumption that even if there are two speakers, the separation is insufficient to be noticeable. Perhaps I could make this configurable for the sake of future tablets with decent separation. I presume external stereo speakers (like I use for testing) will be wired to the headphone jack and will thus appear as if they are headphones.
And for those unaware, mono mode is less noisy than stereo mode when the signal is weak (especially with no external antenna.)
