Here is the result, which you should put in a file that you > name asound.conf and put in /etc: /snip OK, created asound.conf per your instructions. While looking at /etc in Konqueror I found a file called asound.state Looking at the modification dates, Digging further, I find that /etc/asound.state is a link that points to: /var/lib/alsa/asound.state At any rate, asound.state was last modified on 8/14, which means that some mixer (or something) must dynamically alter it. The fact that if shows a volume level indicates to me that it is dynamically modified. I tried listening to that radio station with the new asound.conf with and without the asound.state link. (Before I realized that asound.state was a link, I temporarily renamed it in /etc) In both cases, the realplayer window tried to open and then vanished, and no sound came out anywhere. Here is the asound.state file: state.Intel { control.1 { iface MIXER name 'Channel Mode' value '2ch' comment { access 'read write' type ENUMERATED count 1 item.0 '2ch' item.1 '4ch' item.2 '6ch' } }
