Hi,
I recently came across a strange ASoC volume control. In this case, the values are not in volume order, i e, the control is declared something like below. I believe the numbers correctly match the hardware.
However alsamixer seems not to handle this "reordering" correctly. My question is if this is something that should be fixed in alsamixer (or possibly alsa-lib?), or does one need to write some kind of mapping table in the kernel, just to make something come in volume order to userspace?
Any TLV documentation on what TLVs are valid and invalid is also welcome :-)
static const unsigned int tlv[] = { TLV_DB_RANGE_HEAD(8), 0, 0, TLV_DB_SCALE_ITEM(-100, 0, 1), 1, 1, TLV_DB_SCALE_ITEM(400, 0, 0), 2, 2, TLV_DB_SCALE_ITEM(200, 0, 0), 3, 3, TLV_DB_SCALE_ITEM(1000, 0, 0), 4, 4, TLV_DB_SCALE_ITEM(0, 0, 0), 5, 5, TLV_DB_SCALE_ITEM(800, 0, 0), 6, 6, TLV_DB_SCALE_ITEM(600, 0, 0), 7, 7, TLV_DB_SCALE_ITEM(1200, 0, 0), };
