It was already on. But just in case, I've added it to alsa_amixer cmd list Added also the routes/controls that Pierre pointed on his github UCM ( see [1] ) > Overall, I would say it looks good.

Saved dmesg, logcat and alsa_amixer output in case you want to take a look [2] I'm still having this message on logcat: "out_write: error -1 - cannot prepare channel: Device or resource busy" which happens when trying to ioctl SNDRV_PCM_IOCTL_PREPARE to /dev/snd/pcmC0D0p Maybe the problem is something wrong/missing on Machine Driver... Pierre said It would be good base the code on bytcr_5640... * * * I tried also other thing. So far I've been changing host_ipc_index from 5 to 0 on atom/sst/sst_acpi, because this device's DSDT uses a different IRQ order from what drivers expect. It allows fw loading and card registering, but I was wondering if the other index entries are mapped by the driver. To ensure all indexes are read in the position driver wants, I modified irq order on DSDT, reverted ipc_host_index to 5 and tried booting it. I tested it, but the results are the samewhen using original DSDT and changing host_ipc_index to 0. Saved replaced DSDT and logs here [3] * * * Regards Pstglia [1] - https://drive.google.com/file/d/0BxO6THtB865fQnQyZkx6c05Nbjg/view?usp=sharing [2] - https://drive.google.com/folderview?id=0BxO6THtB865fZk5sSEdrbTVsREU&usp=sharing [3] - https://drive.google.com/folderview?id=0BxO6THtB865fWGU1MTlJazBnZzg&usp=sharing _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
