+## Sound Cards
+
+User may define as many sound card as needed. All sound cards will be group within one global multi channels card.
+As a result, declaring three USB stereo sound card is equivalent to declare one Renesas GEN3 with 6 channels
+
+```
+ -- Sound Card Definition
+ -- ==========================
+ -- local sndcard_sample = {
+ --
+ -- * Mandatory UID will be the ALSA PCM
+ -- ["uid"]= "YAMAHA-APU70",
+ --
+ -- * Mandatory Card might be found by either its devpath, its cardid or cardindex (should provide only one)
+ -- ["devpath"]= "/dev/snd/by-xxx/xxxx, (any path in /dev/snd pointing to a valid sndcard control works
+ -- ["cardid"] = "hw:xx", [xx] may either be a card index or a name (eg: hw:USB)
+ -- ["cardidx"] = N,
+ --
+ -- * Optional Device and subdev
+ -- ["device"] = N, (default 0)
+ -- ["subdev"] = N, (default 0)
+ --
+ -- * Mandotory List of sink channels attached to the card
+ -- ["sink"] = {
+ -- [0]= {["uid"]= "front-right", ["port"]= 0},
+ -- [1]= {["uid"]= "front-left", ["port"]= 1},
+ -- }
+ -- }
+```
+
+Sound card should be group in a table in order to request grouping as a multi channel PCM. Note that this grouping
+relies on ALSA 'multi' plugin and thus inherit of its limits.
+
+```
+ local sndcards= {
+ [0] = sndcard_0,
+ [1] = sndcard_2,
+ [3] = sndcard_3,
+ }
+```
+
+Call
+
+```
+ error= L2C:snd_cards (source, sndcards)
+ if (error ~= 0) then
+ AFB:error (source, "--InLua-- L2C:sndcards fail to attach sndcards=%s", Dump_Table(sndcards))
+ --goto OnErrorExit
