Those also implement the digital routing outside of DAPM. So I thought why not. Most of the times these routings are static, so one can set these from the actual board file, it is kind of hackish, but could do it: codec->write(codec, TWL4030_REG_RX_PATH_SEL, _something_); I don't see to much harm on having it as runtime configurable. As I said I think it is good to have 'full control' over things. About the DAPM things: Now I'm in the process of adding the DAPM mappings for TWL (the Earpiece out now works with DAPM). Altrough there are some obstacles on the road, but slowly and steadily I'm getting there. One more thing: I have asked around the availability of technical documentation for TWL. My copy has the big sign: Sigend NDA is required for Distribution... But, the TPS65950 (also from TI) has the very same audio block as the TWL and the TRM is publically available here: http://focus.ti.com/docs/prod/folders/print/tps65950.html > Implementing digial routing support is on my radar but it's firmly below > the V2 merge. > You obviously know about ASoCv2... Do you have some pointers on what is coming and when? -- Péter _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
