I have done extensive googling on this issue, and I have been unable to
determine what exactly is wrong.

I have a (really) cheap WinTv card (the only number on it is 44801) that
works under windows. I have it setup to give me video just fine...the
problem is that the audio out jack on the card doesn't play anything. I
have audio in on my sound card setup correctly (if I hook up a
microphone to it, any audio gets overlaid onto the tv feed playing on my
tv... (ie..it works)).

I have tried tuner settings of 2 (what it autodetects) and 8 (found it
on one of my google searches), and neither of which seem to work.

I have also tried hooking up headphones to the audio out line of the
capture card, and nothing is playing. The relevant parts of dmesg follows:


Thank you for any help,
Chris Schneider

Have you had a look in ALSA Mixer to see if the input( most likely microphone) is enabled. I had this exact problem. The other problem I found was that KDETV would not give audio output on stereo selection. It worked fine when the setting was on Mono.

I am using Fedora Core 2 with kernel version 2.6.6-1.435.2.3smp.

Video is fine.

My Hauppauge card is described by the following:
NTSC 45231 Rev B423
WinTV Copyright 1998 Hauppauge Computer works, Inc.

I have been using modprobe, insmod and lsmod to experiment with different settings. At the moment, both modules ¨tvaudio¨ and ¨btaudio¨ are loaded.

I just recently saw for the first time output about btaudioś failure to recognizethe very mixer-like entries, as as seen below at the end of the DMESG output.



In my /etc/modprobe.conf, I am at the moment using:

=================================================================

I have been using KDE and employed /usr/bin/kontrol to switch between OSS and ALSA.

I am using an SB!Live audio card, although I get no output from the ¨line out"of the Hauppauge device.

Here is some recent dmesg output:

=============================================================
I´ve been for awhile now in that state of affairs where my each of my attempted fixes may impede its successor.

Itś really, really frustrating to be unable to get sound out of this otherwise functional device.

Any help? I assure you that I have checked the mixer and volume levels. I have tried to use the ¨automute=0¨ insmod option to no avail.

I have checked the cable, trying it in both the ¨line in¨ and the ¨microphone¨ ports in my sound card. I have tried my USB Audigy sound card.

I have tried the various settings of the ¨card=X¨ insmod option.

I have followed Gerd Knorr´s instructions regarding the firmware, and only gotten feedback as shown above in the output from DMESG saying ¨altera who?¨.

I´d really like to win this battle and could use some help.


Thanks in advance for anything!!

Very Ancient thread I know! but I just solved my no audio problem with my Hauppauge WinTV PCI model 45231, rev D523:

for PCLINUXOS 2007 the hcwamc.rbf (all lower case) needed to be saved in the /lib/firmware directory. That is all it took.

Now instead of dmesg saying:
bttv0: no altera firmware [via hotplug]
...it now shows::
bttv0: altera firmware upload ok

Maybe that's possible.

Cheers!
