I have a HP Compaq 8510p 32Bit Machine running opensuse 11.1 which I upgraded from opensuse 11. The sound card is Radeon HD 2600 Series. Anyway, the sound was fine when I got the laptop originally bundled with Vista. It was also fine when I installed opensuse 11. Problems came when I upgraded to opensuse 11.1. The sound quality is bad. The volume is ok when its low, but its low, to a point where I cannot here anything. I thought the problem was a hardware issue, so I had it sent back and they told me hardware was ok. I installed Windows in a partition and the volume is fine. If the volume is high it gets distorted.If the volume is too low, it also gets distorted. Better example is when u listen to an MP3, the beginning is distorted, middle is fine, end is distorted. When I watch a DVD, sound is distorted. I use banshee for audio, Mplayer, VLC and Smplayer for Video and its all the same result.
How do I get the sound to be normal, allowing me to raise without compromising the quality i.e. dropping the bass etc, and on the same levels when I run Windows? I have attached all sorts of output for info. Any help appreciated.
