Programs like XdTV , G4vl, TvTIME, Kradio and others work corectly but when I stop them the sound from the source had been used continue. The only way to turn it off is manually with the mixer or if I start other program which use same sound source.
are you using a card that uses an audio line-in cable?
Yes , I use Manli Much TV002/Behold TV 403 FM and it use line-in audio cable for sound. I also have Suse 9.3 on the same computer , there is none problem with turning off the sound source with TV and Radio application when I shut down the application.
hm. i know that this was never a feature of tvtime. dont know exaclty about other apps. kraxel did anything change regarding VIDIOCSAUDIO in v4l?
I checked 'radio' on my bttv card. Works just fine on 10.0 as well as 10.1 kernel.
Re #5: Shouldn't in theory as it would break the API ... Muting is one of the things which is slightly different on each of the 100 cards out there, so this also could be a driver bug showing up on that specific card only ... Try "v4lctl volume mute on" please, that should quiet the card. If that works the applications are broken. If that doesn't work the driver is broken.
I have tried the conmmand as a user it does not turn off the sound, but gives me segmentetion fault I have tried it as well as root and receive: linux:/home/me # v4lctl volume mute on load_codec_info_from_plugin: dlopen failed for /usr/local/lib/libquicktime/lqt_videocodec.so: /usr/local/lib/libquicktime/lqt_videocodec.so: undefined symbol: quicktime_video_height load_codec_info_from_plugin: dlopen failed for /usr/local/lib/libquicktime/lqt_opendivx.so: /usr/local/lib/libquicktime/lqt_opendivx.so: undefined symbol: quicktime_write_chunk_header load_codec_info_from_plugin: dlopen failed for /usr/local/lib/libquicktime/lqt_rtjpeg.so: /usr/local/lib/libquicktime/lqt_rtjpeg.so: undefined symbol: lqt_rows_alloc load_codec_info_from_plugin: dlopen failed for /usr/local/lib/libquicktime/lqt_dv.so: /usr/local/lib/libquicktime/lqt_dv.so: undefined symbol: quicktime_write_chunk_header load_codec_info_from_plugin: dlopen failed for /usr/local/lib/libquicktime/lqt_lame.so: /usr/local/lib/libquicktime/lqt_lame.so: undefined symbol: lqt_start_audio_vbr_frame load_codec_info_from_plugin: dlopen failed for /usr/local/lib/libquicktime/lqt_vorbis.so: /usr/local/lib/libquicktime/lqt_vorbis.so: undefined symbol: lqt_audio_num_vbr_packets load_codec_info_from_plugin: dlopen failed for /usr/local/lib/libquicktime/lqt_png.so: /usr/local/lib/libquicktime/lqt_png.so: undefined symbol: lqt_colormodel_to_string load_codec_info_from_plugin: dlopen failed for /usr/local/lib/libquicktime/lqt_audiocodec.so: /usr/local/lib/libquicktime/lqt_audiocodec.so: undefined symbol: lqt_read_audio_chunk load_codec_info_from_plugin: dlopen failed for /usr/local/lib/libquicktime/lqt_mjpeg.so: /usr/local/lib/libquicktime/lqt_mjpeg.so: undefined symbol: quicktime_match_32 Deleting quicktime codecs linux:/home/me # but as in previous case the sound was not turn off So what I have to do to have it as it was in SuSE9.2 and SuSE 9.3 (perfectly turning off the sound ) why there works fine with the same hardware? Looking forward for receiving replies.
is this reproduceable with 10.2? Sascha if yes please have a look at this.
Not reproducable here. Please reopen if the problem persists.
