I have recently installed LMDE and I am having problems getting sound to work consistently. It seems to be fine on certain websites, e.g. YouTube and some Internet radio stations. However, with other Internet radio stations I get no sound. I have Wine installed, and it tells me that it cannot see the sound card. If I run Preferences->Sound->Hardware, none of the speaker tests work. Any advice on diagnosing the problem would be appreciated. I have checked /etc/asound.conf, and it already contains the pulse-related lines that another post has recommended be added to this file.
