Re: [Alsa-user] arecord: set_params:1239: Channels count non available

[Roger <rog...@gm...>]

The following source code file seems to be related for ASUS Xonar STX cards, 
supposedly defining Line & Mic inputs, and their capabilities.

/usr/src/linux/sound/pci/oxygen/xonar_pcm179x.c

A little more grepping/searching, I find xonar_wm87x6.c seems to specify the 
mic/line channel profiles, which is then linked into virtuoso.c; Of which is 
likely not used by the STX card?


/usr/src/linux/sound/pci/oxygen/xonar_wm87x6.c

    {   
        .iface = SNDRV_CTL_ELEM_IFACE_MIXER,
        .name = "Line Capture Switch",
        .info = snd_ctl_boolean_mono_info,
        .get = wm8776_input_mux_get,
        .put = wm8776_input_mux_put,
        .private_value = 1 << 0,
    },
    {   
        .iface = SNDRV_CTL_ELEM_IFACE_MIXER,
        .name = "Mic Capture Switch",
        .info = snd_ctl_boolean_mono_info,
        .get = wm8776_input_mux_get,
        .put = wm8776_input_mux_put,
        .private_value = 1 << 1,
    },
    WM8776_BIT_SWITCH("Front Mic Capture Switch",
              WM8776_ADCMUX, 1 << 2, 0, 0),
    WM8776_BIT_SWITCH("Aux Capture Switch",
              WM8776_ADCMUX, 1 << 3, 0, 0),
