By the way CM6206-LX if different to CM6206.
CM6206 has 7.1 channels output and CM6206-LX has 5.1 channels output.
Maybe these init:
/*
* C-Media CM6206 is based on CM106 with two additional
* registers that are not documented in the data sheet.
* Values here are chosen based on sniffing USB traffic
* under Windows.
*/
static int snd_usb_cm6206_boot_quirk(struct usb_device *dev)
{
int err = 0, reg;
int val[] = {0x2004, 0x3000, 0xf800, 0x143f, 0x0000, 0x3000};
for (reg = 0; reg < ARRAY_SIZE(val); reg++) {
err = snd_usb_cm106_write_int_reg(dev, reg, val[reg]);
if (err < 0)
return err;
}
return err;
}
is not sutible to -LX version, because it somehow try turn off channels that are not exist.
But maybe I am totally wrong.
P.S. Device ID is 0d8c:0102
