Hello, this is second attempt to add Philips PSC724 Ultimate Edge sound card support to snd-ice1712 driver. Unlike other snd-ice1712 subdrivers, the codec code is splitted into separate modules and thus reusable by other ice1712 subdrivers.
Well, the problem is that most of ice17xx boards use only a part of channels on codecs. Thus you don't want to expose controls for all channels, too. Otherwise user will get confusing dead controls.
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 Alsa-devel@alsa-project.org http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
