I'm working on jack plug detect for Tegra Harmony, and have a question about automatically disabling speakers when a headphone jack is plugged in. For test purposes, I implemented this as follows: static struct snd_soc_jack_pin harmony_hp_jack_pins[] = { { .pin = "Headphone Jack", .mask = SND_JACK_HEADPHONE, }, { .pin = "Int Spk", .mask = SND_JACK_HEADPHONE, .invert = 1, }, }; ... following the example of: omap/ams-delta.c samsung/rx1950_uda1380.c samsung/h1940_uda1380.c However, I wonder if that's the correct approach; should the plug detect logic only control the headphone output (i.e. only include the first array entry in jack_pins[] above), and leave it up to user-space whether to disable the speaker in this case, using a custom Speaker Function control created by the machine driver, as I see many other drivers expose? Do the jack reports make it up to user-space so that could be implemented? Thanks. -- nvpublic -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
