Hi, I also use this Intel ICH4 on thinkpad R50e, I'm not sure about the reason why these 4 pcm interface is prepared by Alsa. I use plughw:0,0 for playback. plughw:0,0 and :0,3 for capture, so we can use 0 & 3 as duplex.
alsa shows below. $cat /proc/asound/pcm 00-00: Intel ICH : Intel 82801DB-ICH4 : playback 1 : capture 1 00-01: Intel ICH - MIC ADC : Intel 82801DB-ICH4 - MIC ADC : capture 1 00-02: Intel ICH - MIC2 ADC : Intel 82801DB-ICH4 - MIC2 ADC : capture 1 00-03: Intel ICH - ADC2 : Intel 82801DB-ICH4 - ADC2 : capture 1 00-04: Intel ICH - IEC958 : Intel 82801DB-ICH4 - IEC958 : playback 1 01-00: Intel ICH - Modem : Intel 82801DB-ICH4 Modem - Modem : playback 1 : capture 1 Beside 4 which is for SPDIF signal, are the 1 and 2 useless? Or what are they prepared for?
