Im using a HVR-1600 in Fedora 11 x64. I previously had the card working flawlessly in Fedora 10 32-bit. I have tried grabbing the latest firmware as well as drivers. I can see in /var/log/messages that the card is being initialized. But when I do a cat /dev/video1 > test.mpg I get video but no audio. I use it with MythTV and in the backend log all that can be found when switching to the analog tunere is "Not IVTV Driver??" here is the output for lspci -v
01:05.0 Multimedia video controller: Conexant Systems, Inc. CX23418 Single-Chip MPEG-2 Encoder with Integrated Analog Video/Broadcast Audio Decoder
Subsystem: Hauppauge computer works Inc. WinTV HVR-1600

Please help. Thanks, Jayme

Make sure the audio volume is up. Use the "Advanced Volume Control" app
that's buried somewhere under the system menu. (Fedora 11 is such a
hassle for something this basic...)

Also could you provide the output of

$ v4l2-ctl -d /dev/video1 --log-status

when tuned to a good station.

Well, truth be told, the cx18 driver doesn't behave exactly like the
ivtv driver, so MythTV notices at times. :)

Those messages are harmless, IIRC. I use MythTV all the time.

Andy

Thanks for your help so far. With me juggling settings it is now video0 still no audio. I checked all of the options under the advanced volume control and no luck. Here is the output for the card. I see a few things that sand out that might be nothing or might be the issue. "no detected audio standard" is one "audio muted yes" is another ant the last is the "audio microcontroller: stopped". I looked up the mute command for v4l2-ctl and tried that as well but no luck.

It looks like the "audio standard auto-detection microcontroller
firmware" (whew!) didn't get loaded properly.

Some things to do:

1. Check to make sure that /lib/frimware (or wherever) has
v4l-cx23418-dig.fw in it, it is readable, and has a good hash:

$ sha256sum /lib/firmware/v4l-cx23418-dig.fw
fd545dcb14f40e0666b95fdb3a73356e34ee282c217b96fc2740747ce1c5b0c4 /lib/firmware/v4l-cx23418-dig.fw


2. Check for errors in dmesg or /var/log/messages related to
v4l-cx23418-dig.fw failing to load or initialize. Normal loading looks
somehting like this:

[ 16.963093] firmware: requesting v4l-cx23418-cpu.fw
[ 18.302494] cx18-0: loaded v4l-cx23418-cpu.fw firmware (158332 bytes)

[ 18.847667] cx18-0: FW version: 0.0.74.0 (Release 2007/03/12)
[ 19.055046] firmware: requesting v4l-cx23418-cpu.fw
[ 19.397242] firmware: requesting v4l-cx23418-apu.fw
[ 19.845859] firmware: requesting v4l-cx23418-dig.fw
[ 20.368420] cx18-0 843: loaded v4l-cx23418-dig.fw firmware (16382 bytes)
[ 20.409945] cx18-0 843: verified load of v4l-cx23418-dig.fw firmware (16382 bytes)


3. Try recording from the Composite or SVideo in and audio line in
eliminate any problem with the audio processing in the MPEG encoder.




Don't worry about the audio being muted for now; that's normal. We rely
on the microcontroller to unmute the audio when it detetcts a valid TV
audio standard. And since the microcontroller isn't running....

Well I checked the hash and it is fine. When I do dmesg | grep v4l I get:

I tried using the svideo input and through myth I get now sound which might be a config issue on my part but when I do cat /dev/video1 > test.mpg I get audio and video. But when I issue the same command and the input is on tuner with a good channel I get video and no audio when using cat and still no audio in myth. Here is a log status output when I'm using s-video:

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.

I guess some good news and bad news. When I mute and unmute I can see the audio controller stop then start again and everything else goes smoothly but when I check the audio standard I get the output:

cx18-0 843: Detected audio standard: no detected audio standard
cx18-0 843: Configured audio standard: automatic detection

and when I use mplayer I get video but still now audio.
