Hi,
Very often i have no sound when using my PVR-150 tv-card, sometimes i do. The root casus seems to be the way the cx25840 module recognizes the cards possibilities. Normally it is wrong, but i can correct it by modprobing the module again (and sometimes being lucky - there is no method in this): My question is how to solve this so the card is recognized properly. Information about the error (what i can diagnose): When i run: "v4l2-dbg --log-status | grep cx25840" and sound works i get: cx25840 2-0044: Video signal: present cx25840 2-0044: Detected format: PAL-BDGHI cx25840 2-0044: Specified standard: automatic detection cx25840 2-0044: Specified video input: Composite 7 cx25840 2-0044: Specified audioclock freq: 48000 Hz cx25840 2-0044: Detected audio mode: stereo cx25840 2-0044: Detected audio standard: A2-BG cx25840 2-0044: Audio muted: no cx25840 2-0044: Audio microcontroller: running cx25840 2-0044: Configured audio standard: automatic detection cx25840 2-0044: Configured audio system: automatic standard and mode detection cx25840 2-0044: Specified audio input: Tuner (In8) cx25840 2-0044: Preferred audio mode: stereo cx25840 2-0044: Selected 65 MHz format: autodetect cx25840 2-0044: Selected 45 MHz format: chroma When it does *not* work i get (differences marked with ->): cx25840 2-0044: Video signal: present cx25840 2-0044: Detected format: PAL-BDGHI ->cx25840 2-0044: Specified standard: PAL-N cx25840 2-0044: Specified video input: Composite 7 cx25840 2-0044: Specified audioclock freq: 48000 Hz ->cx25840 2-0044: Detected audio mode: mono ->cx25840 2-0044: Detected audio standard: no detected audio standard ->cx25840 2-0044: Audio muted: yes cx25840 2-0044: Audio microcontroller: running cx25840 2-0044: Configured audio standard: automatic detection ->cx25840 2-0044: Configured audio system: BTSC cx25840 2-0044: Specified audio input: Tuner (In8) cx25840 2-0044: Preferred audio mode: stereo Further details: Running on Mandriva 2008.0 using the ivtv 1.0.0 driver in the kernel (2.6.22.9-desktop-1mdv). Because the ivtv programs where not available i grabbed them from source and installed the 1.0.3 version. Living in the Netherlands, so PAL-N should be the proper standard.
