Here is a log status > output when I'm using s-video: > Don't know if it helps.. OK S-video works. (BTW, I tested my DTV set top box analog RF output into the HVR-1600 with the latest v4l-dvb drivers on Fedora 9 (2.26.27) on a 64 bit machine. The tuner audio came through fine for me.) So: 1. the microcontroller firmware image is correct 2. the firmware image bytes are written to the microcontroller properly 3. line-in audio, that bypasses this audio controller, works Yet the microcontroller is both stopped and muted. What can be wrong: 1. The firmware image pointer the kernel provided to the driver is bad - very unlikely 2. The register writes to start up the microcontroller are failing - very unlikely since all the other register writes seem to be working fine 3. Something is actively muting the tuner audio - the most likely cause. Probably something from user space is muting the audio. What to do: Stop the mythbackend, then $ v4l2-ctl -d /dev/video0 -i 0 Video input set to 0 (Tuner 1) $ ivtv-tune -d /dev/video0 -t us-cable -c 4 (or whatever channel) /dev/video0: 67.250 MHz $ v4l2-ctl -d /dev/video0 -c audio_sampling_frequency=1 ( 48 ksps ) $ v4l2-ctl -d /dev/video0 -C audio_sampling_frequency audio_sampling_frequency: 1 $ v4l2-ctl -d /dev/video0 -c mute=1 $ v4l2-ctl -d /dev/video0 --log-status | grep microcontroller cx18-0 843: Audio microcontroller: stopped $ v4l2-ctl -d /dev/video0 -c mute=0 $ v4l2-ctl -d /dev/video0 --log-status | grep microcontroller cx18-0 843: Audio microcontroller: running (should be running!) $ v4l2-ctl -d /dev/video0 --log-status | grep 'audio standard' cx18-0 843: Detected audio standard: BTSC cx18-0 843: Configured audio standard: automatic detection $ mplayer /dev/video0 -cache 8192 And you should be seeing US cable channel 4 with audio. The critical step above is that disabling the mute starts the audio controller running. If that doesn't happen, we'll have to start some serious troubleshooting. > Jayme > > > From: [email protected] > > To: [email protected] > > Date: Fri, 21 Aug 2009 22:26:26 -0400 > > Subject: Re: [ivtv-users] cx18 anlog tv tuner picture but now audio > > > > On Fri, 2009-08-21 at 18:24 -0400, Jayme Shaffer wrote: > > > Thanks for your help so far.
