The controls can be easily hidden by setting its name to NULL. It's even used in the psc724 subdriver. > If these new modules are supposed to be used by other ice1712/ice1724 > sub drivers, they should provide some good binding mechanism, too. > (And that's one of the good reasons why ASoC has been nominated.) They're easy to use, you just need to provide wm87x6_write() function. I think that other subdrivers could be easily converted to use this (with hardware to test). > thanks, > > Takashi > > > Working: all analog outputs (front, rear, center+lfe, headphone) and > > inputs (front mic, rear mic, line, cd, aux), mixer, headphone jack > > detection, suspend/resume > > > > Currently untested: SPDIF > > > > Buggy: switching AGC mode in mixer causes alsamixer to crash - looks like > > it does not like notifications about control activating/deactivating > > _______________________________________________ > > Alsa-devel mailing list > > [email protected] > > http://mailman.alsa-project.org/mailman/listinfo/alsa-devel -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
