But when I have had saa7134 + flyvideo 3000 card working xmms also > worked fine. Ie. Mixer was mixing sound. saa7134 registers oss devices (mixer + dsp), you can record sound diectly from the TV card using the dsp device. Because of that the load order matters, who is loaded first becomes the /dev/dsp device, the other driver /dev/dsp1. You can fix that by adding dsp_nr=1 to the options for saa7134, that will make the module ask for /dev/dsp1 (instead of using the first free device which is the default behavior). > 4.

Just curious if it might > work like that? There are two possible sources for sound. One is the tuner chip which provides mono sound, the other one is the saa7134's internal TV sound decoder. The saa7134 can be switched to three different audio inputs: TV - that is the internal TV sound decoder. Can handle FM-stereo + NICAM, i.e. it gives you stereo sound (if it is working). LINE1 - external input #1, usually connected to the external line-in jack of the TV card. LINE2 - external input #2, usually connected to the tuner's sound output. TV input uses "TV", radio uses "LINE2". The tuner also gives a mono sound signal for TV stations. Starting the radio app makes the driver switch to LINE2, thats why you get (mono) sound then even for TV stations. Adding a section like this one ... /* workaround for problems with normal TV sound */ name: "TV (mono only)", vmux: 1, amux: LINE2, tv: 1, ... to your card in saa7134-cards.c can be used to get the same effect without fiddeling with the radio application.
