Recently new version of Advanced Linux Sound Architecture (ALSA) was released. There are more then 1000 new features, changes and bug fixes in the version 1.0.19. The most interesting are following:
- Improving support of HDA sound for ASUS V1Sn, MCP67 HDMI, Intel DX58SO, NVidia MCP78 HDMI allowed to pass sound over HDMI (very important feature for Linux-based HTPC owners).
- Improving identification of HDA devices Nvidia, Intel, HP, Gateway, Samsung etc.
- Improving support of old kernels 2.2.x и 2.4.x.
I already spent a few days to configure my integrated nVidia sound card for playing sound over HDMI. But without luck. It seems that kernel 2.6.22-14 (stable version LinuxMCE 0710 is based on it) has some problems with recognizing HDMI part of the card. I can see just S/PDIF and analog. Will try to install LinuxMCE 0810 used new kernel (2.6.27-x) and upgrade ALSA up to 1.0.19 to get sound over HDMI.
