HVR1300 not detected by ir_kbd_i2c module

Hi,

my new HVR-1300 is not being detected by the ir_kbd_i2c.ko module. I've tracked down the relevant info in the ir_probe component of the module.

ir-kbd-i2c: in ir_probe. adap->id=40004
ir-kbd-i2c: in ir_probe. adap->id=1001b
ir-kbd-i2cprobe 0x18 @ cx88[0]: no
ir-kbd-i2cprobe 0x6b @ cx88[0]: no
ir-kbd-i2cprobe 0x71 @ cx88[0]: no

and then it exits.

as for my card itself, it loads all the other modules fine. The intialization is exactly the same as shown at
http://de.pastebin.ca/raw/891927

except that the ir-kbd-i2c parts are not there and this line is different

tveeprom 0-0050: Hauppauge model 96019, rev C6A0, serial# 446394

my rev number is D6D3.

What do I do to help debug this?

Rajesh

forgot to add. I've tried the current hg sources of both the main v4l repo and the hvr1300 specific repo. neither works.

Darron Broad pointed me to the patches available at

http://dev.kewl.org/hauppauge/ (get the sfe version for the 1300). The patches applied cleanly about the v4l main tree mercurial source.

That fixed the problem. both ir-kbd-i2c and lirc-i2c detect and initialize the IR receiver on the HVR1300 now.

Thanks for your help Darron!

I apologize if this is not directly related to v4l development. But I suspect people here know the answer to this question.

Does anyone know how to activate the IR transmitter (not receiver) that is on the non-MCE version of the HVR-1300? The firmware states that it has an IR receiver and a transmitter. The receivers works flawlessly now.

I've loaded lirc_serial and tried ports 0x2f8 and 0x3f8. my debugging of the kernel module indicates that data is being written to the UART (in both cases) using the appropriate pulse function but the LED on the transmitter never blinks (checked with a digital cam LCD). I've tried every type supported by the lirc_serial driver. no go.

I'm beginning to suspect that the transmitter does not behave as a serial device and that something else needs to be done. is this correct? if so, does anyone know what? There is precious little information about the transmitting portion of the hvr1300 on the web. what do people use to control their cable boxes?

Thanks,

Rajesh

I've managed to smack down most of the other issues I had. But the last issue with analog recording remains -- I can get audio but it is way too loud.

I'm using the hvr-1300 hg branch with the PAL-BG audio fix (last patch). My input is from my cable box into the composite in of the HVR-1300.

The video is fine but the audio is way too loud. It sounds like the internal gain setting is set way too high. no audio control (alsamixer, v4l2-ctl -c volume 1 etc.) seem to work. The volume never changes.

I have a sample of the audio at http://www.cs.cmu.edu/~rajesh/foo.wav

This was recorded using arecord -D hw:1,0 -c 2 -r 48000 -f S16_LE -t wav > foo.wav
I've replicated this same audio problem using mythtv's live tv function and with mplayer (with the tv:// option)

I noticed that the audio is also finicky. I sometimes get silence or static until I do v4l2-ctl -i 1. This is even with a proper video being displayed.

Any suggestions for fixing this? for reference, cat /dev/video1 > foo.mpg has perfect audio synced with the video.

Rajesh
