In my previous post (Installing XBMC on Ubuntu Server with Broadcom Crystal HD Decoder BCM70015) I explained how I installed XBMC. The video worked awesome. The Intel GMA 950 card on the Wind box supported up to 2048 x 1536 resolution. This was good enough to display 1920 x 1080 (1080p). Although it provides only analog signal it still looks good. With a good HD15 VGA cable I could get clear 1080p video.
The sound from videos was very poor. The inbuilt sound card was not enough. Since the MSI wind has no expansion slots I looked for USB alternatives. The Turtle Beach USB Micro II card with optical output was exactly what I wanted to get Dolby/DTS 5.1 channel sound. With that and a toslink cable I can improve my sound. So I installed it but the problem is there is now no sound.
I researched and found the following relevant links:
I will be trying the above methods and will update on the progress soon.
I now have a working USB Sound Card that passes through HD audio through the optical cable. I have described what worked for me in Part 2.
