Hi All, I have tired to make the sound works on Osprey 220 with btaudio. The video works fine!(after a some patches). I just added a new entry in the tvcards struct in "bttv-cards.c" and it works. See the new entry above: { name: "Osprey220 (fusion878A)", video_inputs: 2, audio_inputs: 1, tuner: -1, svhs: 1, gpiomask: 0x00000303, muxsel: { 2, 3, 1, 1}, audiomux: { 0, 0, 0x00fffcfd, 0x00fffdfd, 0 }, needs_tvaudio: 1, pll: PLL_28, tuner_type: -1, } with this, the video is 100% fine (S-Video and Composite), but the quality of audio is horrible. Can anyone help me? My System: P4 - 1.5GHz, RedHat Linux 7.2, 2.4.17 bttv 0.7.88 Thanks, Danilo Bardusco Globo.com
