It seems that bttv 0.7.44/0.7.45 has a few problems regarding stereo detection on msp34xx. This is what I get when I tune into a channel that is transmitting in NICAM stereo: ,---- | msp34xx: setvolume: 0:0 0x00 0x00 | tuner: tv freq set to 479.25 | msp3410: setting mode: autodetect start (0x0001) | msp3410: detection still in progress | msp3410: current mode: 5.5/5.85 B/G NICAM FM (0x0008) | msp34xx: setbass: 32768 0x00 | msp34xx: settreble: 32768 0x00 | msp34xx: setvolume: 65535:65535 0x73 0x00 | msp34xx: stereo detect register: 0 `---- The actual sound *is* in stereo, so this is mostly a cosmetic problem (xawtv reports mono audio).
