I’ve recently setup a new HTPC with video on HDMI and
audio via IEC958. Unfortunately my amp needs a repair and my TV only supports
audio over HDMI so I thought it might be good to see if it was possible to get
HDMI audio working as the motherboard packaging insists that it is J. I also
have an issue at the moment with the AV sync being out by over 100ms which
hopefully can be resolved by switching to HDMI. I’m quite happy to patch
the ALSA source and/or the Intel video driver if required. So if anyone can
confirm if this is known to work / not work and what might need doing if it doesn’t
work I’d appreciate it. I can re-post on the dev list if more
appropriate. I’ve compiled a few basic details on the system below, I can
post more if required. Will --------------- Motherboard: ABIT iL-90MV Chipset: i945GT 2.6.31-gentoo-r6 * media-libs/alsa-lib Latest version available:
