First off, I have to say I don't really *need* to fix this problem, at
least not anytime soon. I've backported the new cx25840 initialization
code to the 0.3.2w version of the driver, so I do have a version that
works perfectly for everything I use it for. However, I would *like* to
fix this problem, just on general principles. Besides, it might help
someone else someday.
I have two PVR-250's and a PVR-500 in the same box. Up through 0.3.3k
(100% confidence) and 0.3.4f (90% confidence) I had no sound issues at
all. Since 0.3.4p, the audio in a file produced by a PVR-250 is normal
(the same as it ever was) but the audio in a file produced by either
tuner of the PRV-500 is a *lot* louder, to the point of being grossly
distorted and unusable.
Tyler Trafford replied to one of my earlier posts suggesting that part
of the problem might be the lack of volume controls for the cx25840.
Alan Stirling replied to that, suggesting that 0x8D4 and 0x8E4 might be
involved with volume control. Still, as far as I can tell, I am the
only one reporting this problem, which leads me to suspect I have a
configuration or mis-detection problem.
My modprobe.conf options are pretty simple. I still have the
no_black_magic setting because I'm using 0.3.2w for production use,
otherwise I could remove it:
options saa7127 i2c_enable=-1,-1,-1,-1
options cx25840 i2c_enable=1,1 no_black_magic=1
options ivtv ivtv_debug=1 tuner=2,2,57,57
I'm using the ivtv versions of tveeprom.ko, tuner.ko, and msp3400.ko
(100% confidence).
At the end of this note is the debug output for the intialization of
version 0.3.4u of the driver, which has the audio problem. I have
compared it to the output of 0.3.2w, which does not have the audio
problem, and can find no substantial differences in terms of detection
and initialization of the relevant modules.
If anyone has any suggestions for the best way to troubleshoot and
resolve this problem, I would be very grateful.
Thanks!
Bill
