You could try adding a control to toggle GPIOs - can I do it through 'amixer' or I need to change the driver ? The latter. Real programming needed. Regards, Clemens After some web search I cam across 'usb-robot' - http://usb-robot.sourceforge.net/ . Its README file contents are: This file describes the package and how to use it. You need a recent libusb. See INSTALL for details of requirements. See the file INSTALL for instructions on compiling and installing. See the file AUTHORS for who to mail about problems, suggestions, etc. usb-robot = The latest version is always at http://usb-robot.sourceforge.net. The status of this release is beta. There are no known bugs, but virtually no testing has been carried out. This program is to communicate with generic USB devices using libusb. It can be used to send commands to the device directly from the console (usb-robot-slave), or as part of some rapidly prototyped driver in a language like perl or Python. For a really bad example of how you can do that, it comes with a program (usb-robot-master) that translates traces of MS-Windows driver actions into usb-robot-slave commands, so you can get your device to do whatever MS-Windows did to it. You can get these traces from sniffusb version 0.1, which is linked to from the usb-robot homepage. At the moment only control and bulk transfers are supported. Note that to communicate usefully with USB devices you need to be the superuser (root). Starting up === Linux 2.4.2: First load your USB kernel driver. See USB docs for more help. Don't forget to mount the /proc/bus/usb usbdevfs filesystem. *BSD: Does it work at all? Send mail! Running the slave directly == # ./usb-robot-slave product=0x0099 vendor=0x05da This will search the USB buses for the specified device and open its /proc/bus/usb filehandle (via libusb). Now the command prompt will pop up. To see the commands you can use, type help and press return. Running the master == The (unpolished) usb-robot-master perl script can be used to control the usb-robot-slave, using debuglogs produced from sniffusb in conjunction with dbgview. Perhaps perl-5.6.0 is required. I don't know. The following example acts on turnon.log then scansuite.log, using them to control a device with specified product and vendor id. # ./usb-robot-master --session-type=interactive --product=0x99 --vendor=0x5da\ /mnt/d/temp/turnon.log /mnt/d/temp/scansuite.log A session type other than interactive will produce output to STDOUT describing what would be passed to the slave and what output from the slave would be expected. A session type of dump will produce a condensed (more readable) dump of the logs passed to the program. . So, maybe no real programming is needed provided I figure out what control data to send to the card ? Thanks, Sergei. -- Everyone hates slow websites. So do we.

I've enabled playback through Line, I hear nothing when headphones are plugged into line. I'd guess the Line controls are for playback from the line input. Regards, Clemens I didn't run speaker-test, I was using 'sox'. As I wrote, I _can_ get sound out of every default output channel of the 6 available: FRONT OUT, REAR OUT, CEN/BASS OUT. Please pay attention that in numid=6,iface=MIXER,name='Speaker Playback Volume' ; type=INTEGER,access=rw---R--,values=8,min=0,max=197,step=0 : values=197,197,197,197,197,197,197,197 | dBscale-min=-36.93dB,step=0.18dB,mute=0 there are exactly _eight_ (8) values. Again, my question is very specific: what controls should I set in order to make a default input (either Mic or Line) an output - because there are just 6 (3 x 2) default outputs.
