Hi all,
I've had KnoppMyth R5A26 up and running for about a month and working great. However, I've noticed that when I watch live TV or playback anything captured on my PVR-150, the sound is shrill as if the highs (treble) has been extremely boosted. I don't think it's my Soundblaster card since CD's and videos sound normal.
Does anyone know if there is an issue with the Hauppauge PVR-150 drivers that might cause this? Is there anywhere I can adjust the sound quality when capturing video?
Many thanks! (And yes, I'm a linux newbie so sorry if this post has an obvious answer. Let me know if there is some additional information I should be providing)

*bump*
If anyone knows how to set the audio capture options on a PVR-150, I sure would love to hear it. Even if you don't think there is a way, I'd love to hear that too.
Cheers,
abc

...pvr 150 is a newer card (ish). Try the RA30 version? Newer drivers might help ?
have you tried alsamixer ? theres some "3d" affects on the audio there, perhaps one got ticked on ? or some bass/trebel control ?
Or maybe the input is funky from your source, try a discman or mp3 player see if its same same problem using live tv with music ?
HTH,
JC

If it is a newer 150, then ivtv 4.1 is what you'll want to try. You'll have to compile it yourself however (easy...).

I upgraded my ivtv version to 0.4.2 based upon cesman's suggestions. This version seems to be much more mature and does a lot of auto-discovery (which is good), but I'm having problems getting it to load the firmware. Here's the capture from my dmesg log:
Code: bttv: driver version 0.9.15 loaded
bttv: using 8 buffers with 2080k (520 pages) each for capture
ivtv: ==================== START INIT IVTV ====================

ivtv: ==================== END INIT IVTV ====================
cx2388x v4l2 driver version 0.0.4 loaded
Yes, I've placed the firmware in the /usr/lib/hotplug/firmware/ which is appropriate for this version of ivtv. I also checked to make sure that my the previous directory was listed in my hotplug path.
I'm guessing that the ivtv firmware is failing to load because bttv is loading it's drivers right before ivtv loads. However, I can't figure out how to stop it from loading or make it load after ivtv.
Any ideas? I can't watch TV or record because of this firmware issue.
Cheers,
abc

You need to "edit your /etc/modules file and remove the line that says "ivtv" around line 45." http://www.knoppmythwiki.org/index.php?page=CompileIvtvI did originally forget that, but I've since removed it and I still have the same problem. I double-checked it and "ivtv" is NOT in my /etc/modules.
Any other ideas?
I REALLY appreciate your help!

What does this show on your machine?
Code: root@black2:~# ls -al /usr/lib/hotplug/firmware/v4l*
-rw-r--r-- 1 root root 262144 Jan 18 21:18 /usr/lib/hotplug/firmware/v4l-cx2341x-dec.fw
-r--r--r-- 1 root root 376836 Jan 18 21:20 /usr/lib/hotplug/firmware/v4l-cx2341x-enc.fw
-rw-r--r-- 1 root root 155648 Jan 18 21:21 /usr/lib/hotplug/firmware/v4l-cx2341x-init.mpg
-r--r--r-- 1 root root 14264 Jan 18 21:20 /usr/lib/hotplug/firmware/v4l-cx25840.fw
OBTW - looks like we have the same generation of PVR-150 card, even the serial numbers aren't that far apart.... Code: Jan 18 23:07:55 black2 kernel: tveeprom: ivtv version
Jan 18 23:07:55 black2 kernel: tveeprom: Hauppauge: model = 26032, rev = C199, serial# = 8163083

Here it is:
Code: root@mythtv:~# ls -al /usr/lib/hotplug/firmware/v4l*
-rw-r--r-- 1 root root 262144 Jan 20 18:27 /usr/lib/hotplug/firmware/v4l-cx2341x-dec.fw
-r--r--r-- 1 root root 376836 Jan 22 08:31 /usr/lib/hotplug/firmware/v4l-cx2341x-enc.fw
-rw-r--r-- 1 root root 155648 Jan 20 21:02 /usr/lib/hotplug/firmware/v4l-cx2341x-init.mpg
-r--r--r-- 1 root root 14264 Jan 22 08:30 /usr/lib/hotplug/firmware/v4l-cx25840.fw
I'm stumped. It should be recognizing them. Could it be that bttv is loading first?

Try copying those files into /lib/modules/ as well on the off chance that R5A30.1 has different settings for the hotplug stuff...

I copied the files to /lib/modules/ but still no dice. I'm using R5A26 right now, perhaps I should upgrade to R5A30.1?
Thanks again!

Yes, please do and report back if it fixes the issue. I'm in the deciding phase of what PVR to buy , the 150/250/350. It seems almost like a crapshoot anyway.

I have a similar problem (running IVTV 0.4.2). If I do "ivtvctl -q 1" on a remote terminal whilst TV is playing it fixes the sound. Exiting TV and going back in seems to reset the sound input back to the wrong/one. Is there a way of setting the sound input for the card permanently. I tried setting this in set_ivtv_params with no luck
