Takashi, On the XPS M1330 (and XPS M1530) the SPDIF pin of the 9228 is hooked to the HDMI as these laptops were made before the HDMI portion had their own audio codec portion of the transceiver. So technically, it should be pretty simple ;) IDT PC Audio Demo/Linux/Test -----Original Message----- From: Takashi Iwai [mailto:tiwai@xxxxxxx] Sent: Friday, February 29, 2008 5:57 AM To: Armando Di Cianno Cc: Tellman, Steven; alsa-devel@xxxxxxxxxxxxxxxx Subject: Re: HDMI v.

Thanks. It's a bit hard to judge right now. So far, many HDMI devices seem not working even though it appears set up properly. I've heard that ATI HDMI devices are working, but others are not well, e.g. on some devices only left channel is output and on others silent. Moreover, I'm not pretty sure whether HDMI is connected from the digital out of STAC codec. On many devices (e.g. ASUS ones), there is a dedicated codec for the HDMI transmitter. So, right now, it's total lack of (hardware) information, unfortuantely. We may try some verbs for HDMI that are not used in the current ALSA code, at least. These verbs were extended later...
