Hi, I initially had audio problems in MythTV that were later resolved at the end of July with this patch.
http://linuxtv.org/hg/v4l-dvb/rev/6fc3c82281f3 But with the latest driver I'm have a different audio problem - no audio at all except for the occasional screech. System sounds still work fine so I've ruled out sound card problems. I'm using the analog tuner on Ubuntu Hardy with the Intrepid ivtv package on an AMD64 Opteron with 4G RAM. Here's some system info: $ ivtvctl --version ivtvctl version 1.2.0 (tagged release) $ dmesg |grep cx18 [ 261.019358] cx18: Start initialization, version 1.0.0 [ 261.019472] cx18-0: Initializing card #0 [ 261.019520] cx18-0: Autodetected Hauppauge card [ 261.020056] cx18-0: Unreasonably low latency timer, setting to 64 (was 32) [ 261.021537] cx18-0: cx23418 revision 01010000 (B) [ 261.217148] cx18-0: Autodetected Hauppauge HVR-1600 [ 261.217195] cx18-0: VBI is not yet supported [ 262.090741] tuner 3-0043: chip found @ 0x86 (cx18 i2c driver #0-1) [ 262.131668] tuner 3-0061: chip found @ 0xc2 (cx18 i2c driver #0-1) [ 262.131751] cs5345 2-004c: chip found @ 0x98 (cx18 i2c driver #0-0) [ 262.178526] cx18-0: Disabled encoder IDX device [ 262.178626] cx18-0: Registered device video0 for encoder MPEG (2 MB) [ 262.178678] DVB: registering new adapter (cx18) [ 262.318897] cx18-0: DVB Frontend registered [ 262.318971] cx18-0: Registered device video32 for encoder YUV (2 MB) [ 262.319038] cx18-0: Registered device video24 for encoder PCM audio (1 MB) [ 262.319107] cx18-0: Registered device radio0 for encoder radio [ 262.319978] cx18-0: Initialized card #0: Hauppauge HVR-1600 [ 262.320050] cx18: End initialization [ 278.130281] cx18-0: loaded v4l-cx23418-apu.fw firmware V00120000 (141200 bytes) [ 278.500794] cx18-0: loaded v4l-cx23418-cpu.fw firmware (158332 bytes) [ 278.504205] cx18-0: FW version: 0.0.74.0 (Release 2007/03/12) [ 279.169571] cx18-0: loaded v4l-cx23418-dig.fw firmware (16382 bytes) $ v4l2-ctl -d /dev/video0 --log-status Status Log: [ 1163.389925] cx18-0: ================= START STATUS CARD #0 ================= [ 1163.411465] tveeprom 2-0050: Hauppauge model 74541, rev C6B6, serial# 3326793 [ 1163.411471] tveeprom 2-0050: MAC address is 00-0D-FE-32-C3-49 [ 1163.411475] tveeprom 2-0050: tuner model is Philips FM1236 MK5 (idx 116, type 43) [ 1163.411479] tveeprom 2-0050: TV standards NTSC(M) (eeprom 0x08) [ 1163.411482] tveeprom 2-0050: audio processor is CX23418 (idx 38) [ 1163.411484] tveeprom 2-0050: decoder processor is CX23418 (idx 31) [ 1163.411488] tveeprom 2-0050: has radio [ 1163.411493] cx18-0: Video signal: present [ 1163.411496] cx18-0: Detected format: NTSC-M [ 1163.411499] cx18-0: Specified standard: NTSC-M [ 1163.411501] cx18-0: Specified video input: Composite 7 [ 1163.411504] cx18-0: Specified audioclock freq: 32000 Hz [ 1163.411511] cx18-0: Detected audio mode: mono [ 1163.411514] cx18-0: Detected audio standard: no detected audio standard [ 1163.411517] cx18-0: Audio muted: yes [ 1163.411520] cx18-0: Audio microcontroller: running [ 1163.411523] cx18-0: Configured audio standard: automatic detection [ 1163.411526] cx18-0: Configured audio system: BTSC [ 1163.411529] cx18-0: Specified audio input: Tuner (In8) [ 1163.411532] cx18-0: Preferred audio mode: stereo [ 1163.412726] cs5345 2-004c: Input: 1 [ 1163.412729] cs5345 2-004c: Volume: 0 dB [ 1163.412733] tda9887 3-0043: Data bytes: b=0x14 c=0x30 e=0x44 [ 1163.412737] tuner 3-0061: Tuner mode: analog TV [ 1163.412740] tuner 3-0061: Frequency: 77.25 MHz [ 1163.412743] tuner 3-0061: Standard: 0x0000b000 [ 1163.412747] cx18-0: Video Input: Tuner 1 [ 1163.412749] cx18-0: Audio Input: Tuner 1 [ 1163.412752] cx18-0: GPIO: direction 0x00003001, value 0x00003001 [ 1163.412755] cx18-0: Tuner: TV [ 1163.412758] cx18-0: Stream: MPEG-2 Program Stream [ 1163.412761] cx18-0: VBI Format: No VBI [ 1163.412764] cx18-0: Video: 720x480, 30 fps [ 1163.412767] cx18-0: Video: MPEG-2, 4x3, Variable Bitrate, 4500000, Peak 6000000 [ 1163.412772] cx18-0: Video: GOP Size 15, 2 B-Frames, GOP Closure [ 1163.412776] cx18-0: Audio: 32 kHz, MPEG-1/2 Layer II, 384 kbps, Stereo, No Emphasis, No CRC [ 1163.412781] cx18-0: Spatial Filter: Manual, Luma 1D Horizontal, Chroma 1D Horizontal, 0 [ 1163.412785] cx18-0: Temporal Filter: Manual, 8 [ 1163.412788] cx18-0: Median Filter: Off, Luma [0, 255], Chroma [0, 255] [ 1163.412791] cx18-0: Status flags: 0x00200001 [ 1163.412794] cx18-0: Stream encoder MPEG: status 0x0000, 0% of 2016 KiB (63 buffers) in use [ 1163.412798] cx18-0: Stream encoder YUV: status 0x0000, 0% of 2048 KiB (16 buffers) in use [ 1163.412802] cx18-0: Stream encoder PCM audio: status 0x0000, 0% of 1008 KiB (63 buffers) in use [ 1163.412806] cx18-0: Read MPEG/VBI: 8210432/0 bytes [ 1163.412809] cx18-0: ================== END STATUS CARD #0 ================== The odd thing from this status is that the audio is muted and it stays muted even when I run v4l2-ctl -c mute=0. -- Richard _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
