I recently put together a new computer as an HTPC. I've tried a few different flavors of Linux on it before settling on Lubuntu. The only problem? I can't get any sound out from the system whatsoever.
I've tried both Lubuntu 14.10, and Lubuntu 14.04. I was able to get the audio working (albeit crackling) when I had Ubuntu 14.04 and Ubuntu 14.10 installed. However, since both had more processing overhead and more features than I was going to use, I stepped down to Lubuntu.
As the header says, I'm running my audio to my TV via HDMI, but I'm getting absolutely nothing out of it. When I run alsamixer, it identifies my card as "HD-Audio Generic", and my chip as "ATI R6xx HDMI". I know the ID for the device is 0,3, but that doesn't do me much good since I'm not much of a Linux power user.
Does anyone have any ideas to help me out? I've been working on it all week and it's driving me nuts. :/
After a little bit more testing, it appears no audio is working on the system at all. I plugged some headphones in, set the default audio output to the analog jack, and still got nothing. I verified nothing was muted, my sound was turned up to a decent volume... I still have no idea.
