ALSA: Setting default device (Not card, but device)

This seems to be a riddle that nobody can solve;

- The system only has one card by the name of 'Intel'
- That card is the regular 6 3.5mm jack soundcard.
- I have a mic plugged into the red microphone plug
- I open up Audacity and go to preferences, there are two microphone plugs, 'hw:0,0' and 'hw:0,2'
- I have no idea where 0,0 is and it doesnt make any sound, I plugged the mic into every plug on the board and nothing records.
- i can set Audacity to use 0,2 and then it will record my voice just fine

When I open up xfce's mixer I see that there are two mic plugs:

Apparently "Front Mic" is the device that is hw:0,0 right now/

Now when I play Savage2 I don't have an option to choose the device, I can choose the soundcard but that doesn't help. How do I set the default Device so that the game uses hw:0,2 in push-to-talk?

Re: ALSA: Setting default device (Not card, but device)

Nothing? I knew it is something close to impossible :s

I have literally used Windows for about 2 weeks now ONLY so that I can play savage2 and use my mic in-game. Why is it so hard to do in here?

Is this something that could be posted in a ALSA bug tracker?

Re: ALSA: Setting default device (Not card, but device)

from the alsa archwiki:

"Setting the default Microphone/Capture Device
Some applications (Pidgin, Adobe Flash) do not provide an option to change the capture device. It becomes an issue if your microphone is on a separate device (i.e. USB webcam or microphone) than your internal sound card. To change only the default capture device, leaving the default playback device as is, you can modify your ~/.asoundrc file to include the following:

pcm.usb
{
    type hw
    card U0x46d0x81d
}

pcm.!default
{
    type asym
    playback.pcm
    {
        type plug
        slave.pcm "dmix"
    }
    capture.pcm
    {
        type plug
        slave.pcm "usb"
    }
}

Replace "U0x46d0x81d" with your capture device's card name in ALSA. You can use 'arecord -L' to list all the capture devices detected by ALSA."

EDIT: maybe i didn't read your post well enough.. im just guessing here but maybe you can replace card U0x46d0x81d with
device name_of_device..

maybe..

Re: ALSA: Setting default device (Not card, but device)

hmm. does this work?

pcm.mic
{
    type hw
    card "hw:0,2"
}
pcm.!default
{
    type asym
    playback.pcm
    {
        type plug
        slave.pcm "dmix"
    }
    capture.pcm
    {
        type plug
        slave.pcm "mic"
    }
}

?

you probably have to restart the apps using alsa..

Re: ALSA: Setting default device (Not card, but device)

no wait. neither card nor  device work with that argument.. (where do i find info about this??) but it might still work with only "U0x46d0x81d"....
