[alsa-devel] [CONF] All C-Media Codecs based 5.1 Channel USB- Headsets
Report to devlist as requested from USB-Audio.conf header:
1. all this headsets with windriver inf files + manual showing c-media driver must have the cm106x series 7.1 channel usb-codec in. there's no other from c-media for the design of 5.1 channel usb headsets available at this time, see:
http://www.cmedia.com.tw/?q=en/usb_audio
2. the headset interface shows up with 8 channels in lsusb -v , 1 8-ch pcm in /proc, and must be driven with surround7.1 pcm plug instead of surround5.1 or it will not work. speaker-test program works with -c6 -Dsurround7.1, test with -c8 works too, but shows that no SideL/R -speakers connected/routed/downmixed ( Speedlink Medusa 5.1 Mobile USB Headset, cm106L)
3. it works instantly without extra config using programs that allow specifying (-D)surround7.1 like VDR and MPlayer, VLC did not so far (maybe can do with special commandline) and therere maybe other unconfigurable (or buggy?) players that need a missing extra cm106 CARD configfile showing those apps a 5.1 channel device instead a 7.1.
i've done none so far, the config file language (especially routing and mappings) is not well documented, sorry.

since yesterday VLC does work fine now with the cm106L device, just select the alsa device from the list in VLC config, MPlayer should too, then. Noteworthy, especially VLC's software equalizer brings a great *music sound quality boost* in, it is amazing! :) sorry for the misreport, but audio device open errors showed up once, don't know the cause.
system is debian lenny (testing).

OK, and what about surround40? Does it work as is (I don't expect so, though)?
For adding the proper configuration, please check the content of /proc/asound/cards. It gives the name string. If the proc entry is like:
0 [Foo ]: FOO - FOO BAR FOO BAR DEVICE (Blah 0.0)
then "FOO BAR" is the name string that we need to pass. (FYI, "FOO" is the driver string, "Foo" is the ID string and "FOO BAR DEVICE (Blah 0.0)" is the longname string.)
Now add the following to ~/.asoundrc:
USB-Audio."FOO BAR".pcm.surround51 { @args [ CARD ] @args.CARD { type string } type route ttable.0.0 1 ttable.1.1 1 ttable.2.4 1 ttable.3.5 1 ttable.4.2 1 ttable.5.3 1 slave { pcm { type hw card $CARD device 0 } channels 8 } }
Also, /proc/asound/card*/stream* files would be helpful to understand more, at best, together with lsusb -vv output.

seems to work fine if i specify default:1 as "stereo playback device" in Xine-UI, tested yesterday, well it is a headphone, so it is hard to locate speakers but you get double the volume from parallel speaker drive, 5.1 CH is lower volume ;)
for stereo playback we must assure LFE+Center is off, respectively or stereo maybe eliminated acoustically. for Xine it sounds not like, but for VLC, but thats real subjective. the headset has 3 speakers per ear, i dont know the LFE+Center circuits... so plug:surround40 is a good idea.
For adding the proper configuration, please check the content of /proc/asound/cards. It gives the name string.
the "name" is from the drivers "id" parm, right?
If the proc entry is like:
0 [Foo ]: FOO - FOO BAR FOO BAR DEVICE (Blah 0.0)
then "FOO BAR" is the name string that we need to pass. (FYI, "FOO" is the driver string, "Foo" is the ID string and "FOO BAR DEVICE (Blah 0.0)" is the longname string.)

hm. this seems to change nothing here, wether with VLC or vdr with -a '/usr/bin/ac3dec -6 -D surround71:CARD=Audio' (ac3dec with my "enable -6 with DD2.0 input patch from alsa bugzilla).
speaker-test -Dsurround51:CARD=Audio -c 6 -t wav still err "no conf avail.".
speaker-test -Dsurround71:CARD=Audio -c 6 -t wav is fine.
speaker-test -Ddefault:CARD=Audio -c 6 -t wav aligns speakers wrongly with or without /etc/asound.conf
anyway. i'm fully satisfied. :) if You want me to test more, drop me a note.
