[DONE] No sound from Hauppauge PVR 250 captur card

[doktor5000]

I' ve used this card succesfully some years ago (M6 or 7?) to record some VHS cassettes
Now I run M9 on an older desktop that still accepts this card. I got it running fairly easily with the V4L2 Test Bench, but only video, no sound.
Some commands:

I googled for this "audio absent" to no avail and AFAICS there is nothing muted.

Well there are quite a few hits for that, mostly either because the model was not correctly detected and you need to configure the options for the bttv kernel module to detect the model properly.
See e.g. https://forums.zoneminder.com/viewtopic.php?t=22373 or https://www.linuxquestions.org/question ... 175427496/

You're also missing information what command you're using to test it, and what you selected there as audio input.

As stated above I tested with v4l2 test utlility qv4l2. This has no audio settings available. Which is logical in this instance.
About the links you sowed: thye first one looks quite applicable, but it requires changes in the bttv.conf file, and that doesn't exist on the PC.
Further I found the number for identification of the card (80), but the example provided another paramater which is not clear to me.

[hviaene]

As forthe second link: I got verysimilarresponses on the commands, except the last one.

Code: Select all

# cat /dev/dsp1

Well that's only for the video part, so that's expected.

Well you need to create that if you want to configure persistent options for that kernel module.

[hviaene]

I created the file in /etc/modprobe.d. But no effect.
lsmod shows the bt87x in the snd modules, and thez device is seen in the mixer. But the journalctl keeps saying "audio absen".
I start to think that this card which has been laying around for years has developed some disease.

Mind to post the actual file and content that you created? Together with output from

contents of bttv.conf in /etc/modprobe.d

You may need to add an option for the sound module

Code: Select all

options snd-bt87x load_all=1

and maybe also add

Code: Select all

digital_rate=44100

for snd-bt87x as it seems to default to 32000 Hz
Also might not hurt to add

Code: Select all

bttv_verbose=2 bttv_debug=1

as options for bttv to get more verbose output.
And then get new journal logs, maybe add complete unfiltered journal logs as an attachment here.

On a related note, did you connect the lineout of your capture card to the linein of the soundcard? Otherwise IIRC you need to use the snd-bt87x module to grab the audio.

See also https://www.kernel.org/doc/Documentatio ... /bt87x.rst
and the latter part of this page for audio recording: https://tldp.org/HOWTO/html_single/BTTV/

https://docs.kernel.org/admin-guide/media/bttv.html also says the card needs a firmware file which you might need to extract from the driver DVD.

I tried all ypour suggestions to no avail. I still had an Win XP licence lying around, installed that one on the PC, and tried to configure the card. But it wouildn't even recognize the board.
To me that's end of story, it goes on the scrap.
Lots of tx for all your goodwill and effort, I'll have to look for another solution to get these VHS cassettes digitized (got a few options).
