My configuration is this: debian sarge, pinnacle pctv stereo, creative live 5.1, 4.1 speakers; the tv tuner and the sound card are connected via an internal cable to the aux port of the sound card. When watching movie or listening to music all 4 satellites work but when watching tv only the front speakers work and the volume can not be changed from the program I'm watching the tv (tvtime or mplayer). I can change the volume only from alsamixer or the volume control of the speakers. What should I do to get all 4 speakers working when watching tv?
