According to the data sheet it should be 0x88. If you change it to 0x80 there is no longer any sound? Are you sure? The same is true for the PORT2 setting. The datasheet says it's a 'don't care' setting, yet something seems to care! I have done more investigation today. I have a plugged a source into the external line-in of the PVR, and I have found that the sound quality is also very bad. This lead me to think the cx25840 was at fault. I removed the CX25840_SET_START_MICROCNTL(0x01) line which has been added recently, and most of the artefacts (clicking noises) disappeared : the sound from the line-in is now perfectly clean and much louder. Interesting. The sound from the radio tuner is also cleaner but I still have a bit of background noise. However, I have tested the card under Windows and I got approximately the same noise. I have also tested a PVR-USB2 under Windows with the same result. So I'm beginning to suspect either the outdoor antenna, our distribution system or the tuners of the PVRs. I'll try tomorrow with a hi-fi tuner so I'll know for certain. But the good news is that Linux radio support is up to par with Windows. From that point I have tried to remove yesterday's patches. Programming 0x88 into the tuner now works - either I was mistaken yesterday, or the MICROCNTL stuff fixed it - so the tuner patch isn't needed. However the PORT1 setting is a no-go : if it is enabled, ivtv-radio -s doesn't return anything, and tuning to a valid frequency only gives static.

Maybe Hauppauge wired it to some component which fucks up everything. I haven't had the courage yet to remove the tuner cover and try to find what the chip is connected to. I'm still mystified by this chip to be honest. I have also seen in another post that some people do not get sound on TV if PORT1 is not enabled. It is not my case, but maybe we should only enable PORT1 on TV and disable it on radio. Sound quality is still very bad, I can hear what kind of music it is but there is a lot of background noise, which is surprising because I have an outdoor FM antenna. Do you get perfect sound quality with your installation ? I have to extend my cable radio signal to my computer first. I'm currently using the provided aerial so I have a lousy signal. In a few weeks time I hope to buy some additional cabling in order to properly test the radio. In my experience the provided aerial gives good enough a signal. At least you may have additional noise background, but given the artefacts I had with the MICROCNTL stuff you can clearly hear the difference between the Linux and Windows drivers, if you have Windows on your machine. I live in an apartment block and so I am surrounded by other apartments. I suspect there is quite a bit of EM pollution. Do you need any sponsoring for your additional radio cabling ? No, it's just that I have to figure out what I want (I want to lay down some other cables too) and when to find the time to do it. As requested I have loaded tuner and tda9887 with debug and secam=L, using the latest 0.3.9 trunk. Can you try another test: this time with option ivtv_std=3 for the ivtv module. This sets the standard to SECAM. The tda9887 option 'secam=L' should not be used for this test. Here you are : Thanks. Are you able to do a test under Windows with this card? I'd like to see what Hauppauge does. Especially since I have the same tuner, but using PAL. It makes for a good comparison. I have a system running Windows. It's been very hard to get it running, but today we finally managed to get the 150MCE to be recognized as a 150 with radio. What are you precisely interested in ? I'll mail you some instructions. Attached is my current patch against the svn. Tell me if radio works for you with it. I'll try later.

I think we're close to cracking it. When you make a log under Windows, can you also make a separate log where the radio is started and tuned to a few channels? Thanks.

Lastly, what's the md5sum of the HcwMakoA.ROM file you're using ? I have found two versions and I'd like to use the same as you. 3a4803384f749d644ee1f1ca9dcb12fa /lib/modules/HcwMakoA.ROM That did the trick ! I had (probably) older versions of the file taken from the installation CDs : 3a4803384f749d644ee1f1ca9dcb12fa /lib/modules/HcwMakoA.ROM a6f6a90a3be338cdb89d59e835798408 /lib/modules/HcwMakoA.ROM.bak c5749da3eb141e87634ff1e2c1e6f390 /lib/modules/HcwMakoA.ROM.bak2 The other two versions were causing the /dev/video24 = 0x... problem. Now with the patch below I can hear the radios. The patch to ivtv-driver.c is needed because otherwise ivtv-radio -s doesn't return any station. It doesn't seem to disturb anything else.
