Ok, I'll do it ASAP.

I'm still working on it since I'd like to record from 4 channels at time but I can't... here my custom settings:
static unsigned char int1410_eeprom[] __devinitdata = { [ICE_EEP1_CODEC] = 0x1f, [ICE_EEP1_ACLINK] = 0x00, [ICE_EEP1_I2SID] = 0x01, [ICE_EEP1_SPDIF] = 0x03, [ICE_EEP1_GPIO_MASK] = 0xff, [ICE_EEP1_GPIO_STATE] = 0xff, [ICE_EEP1_GPIO_DIR] = 0xff, };
static int __devinit snd_ice1712_int1410_init(struct snd_ice1712 *ice) { printk("%s\n", __FUNCTION__);
/* Set the pro AC97 codecs */ ice->ac97_codecs = 4;
/* Set the analog DACs/ADCs */ ice->num_total_dacs = 8; ice->num_total_adcs = 8;
return 0; }
/* entry point */ struct snd_ice1712_card_info snd_ice1712_eurotech_cards[] __devinitdata = { { .subvendor = ICE1712_SUBDEVICE_INT1410, /* a dummy id */ .name = "Eurotech INT 1410", .model = "int1410", .chip_init = snd_ice1712_int1410_init, .build_controls = snd_ice1712_int1410_add_controls, .no_mpu401 = 1, .eeprom_size = sizeof(int1410_eeprom), .eeprom_data = int1410_eeprom, .driver = "int1410", }, { } /* terminator */ };
But I'm a bit confused regarding how to enable such feature. Again, should I use a multitrack audio recorder as ecasound or I can just use arecord with some magic options? :)
Thanks,
Rodolfo
