Hi, I am not a member of the list. Please cc me in responses. ------------------------------ i have the leadtek winfast tv2000xp expert tv card. it uses the cx8800/xx drivers. the sound is going through the cd channel.
when i install a v4 kernel, there is a screeching sound about the time it seems the modules get loaded during the boot process. this doesn't happen on the v3.17 kernel i am currently running. interestingly when i open tvtime in the 4.x kernel the screeching sound stops.but tvtime does not pickup the audio from the tv line. it just has a shhhhhhhhh sound. when i blacklist these modules on the 4.x kernel, the screeching sound doesn't happen. the screeching sound - https://dl.dropboxusercontent.com/u/17100344/Debian.wav lsmod | grep cx (on the 3.17 kernel) cx8800 31477 1 cx88xx 80236 1 cx8800 btcx_risc 4192 2 cx8800,cx88xx tveeprom 14712 1 cx88xx videobuf_dma_sg 10902 2 cx8800,cx88xx rc_core 20852 3 cx88xx,rc_winfast v4l2_common 7249 3 tuner,cx8800,cx88xx videodev 148569 7 tuner,cx8800,cx88xx,gspca_main,v4l2_common,gspca_zc3xx videobuf_core 19391 3 videobuf_dma_sg,cx8800,cx88xx i2c_algo_bit 5789 2 cx88xx,nvidiafb i2c_core 44594 16 drm,i2c_i801,tuner,tda8290,tda9887,tea5767,i2c_algo_bit,cx8800,cx88xx,fb_ ddc,nvidia,v4l2_common,tveeprom,tuner_simple,videodev,nvidiafb lsmod | grep cx (on a 4.x kernel) cx8800 27705 0 cx88xx 79974 1 cx8800 tveeprom 15368 1 cx88xx rc_core 20973 3 cx88xx,rc_winfast videobuf2_dma_sg 8729 1 cx8800 videobuf2_core 41082 2 cx8800,cx88xx v4l2_common 5589 4 tuner,cx8800,cx88xx,videobuf2_core videodev 148755 7 tuner,cx8800,cx88xx,gspca_main,v4l2_common,videobuf2_core,gspca_zc3xx i2c_algo_bit 5862 2 cx88xx,nvidiafb i2c_core 46991 16 drm,i2c_i801,tuner,tda8290,tda9887,tea5767,i2c_algo_bit,cx8800,cx88xx,fb_ ddc,nvidia,v4l2_common,tveeprom,tuner_simple,videodev,nvidiafb i noticed this regarding the .config files both have the following CONFIG_VIDEO_CX88=m CONFIG_VIDEO_CX88_ALSA=m CONFIG_VIDEO_CX88_BLACKBIRD=m CONFIG_VIDEO_CX88_DVB=m CONFIG_VIDEO_CX88_ENABLE_VP3054=y CONFIG_VIDEO_CX88_VP3054=m CONFIG_VIDEO_CX88_MPEG=m i noticed the 3.17 kernel has btcx_risc and 4.x doesn't. so i did this comparison # cat /boot/config-3.17-4.dmz.2-liquorix-amd64 | grep BTC CONFIG_ATH9K_BTCOEX_SUPPORT=y CONFIG_RTLBTCOEXIST=m CONFIG_VIDEO_BTCX=m and # cat /boot/config-4.0-5.dmz.3-liquorix-amd64 | grep BTC CONFIG_ATH9K_BTCOEX_SUPPORT=y CONFIG_RTLBTCOEXIST=m the config_video is missing. is that relevant because video plays? here is some system info around audio lspci -vv | grep -a10 Audio 00:1a.7 USB controller: Intel Corporation 82801JI (ICH10 Family) USB2 EHCI Controller #2 (prog-if 20 [EHCI]) Subsystem: ASUSTeK Computer Inc.
