ok ill give that a try, though i think i may have another direction that
could be the issue, i had a suspicion but since i had a very similar
issue with out ivtv affecting things i didnt think so, but due to the
failure i just had and recovered from, i am suspecting it may be!

i noticed a point on one of the ivtv posts about ivtv and sata drives,
now over all i have had little issue and nothing directly relating to
that post so i didnt think it was related, but i have a raid5 array with
4 drives setup, and i have bin having an intermittent issue of one of
the drives fails out (SDC) and goes non responcive, and i had an issue
building the array (same issue) when building the array with an older
kernel driver, but with the newer 2.6.25 kernel i dont have the building
issue but every so often the drive fails and my raid array goes
degraded, not a big deal and not that often, reboot remove and add drive
and it rebuilds and it works fine, but now i have the "temp
set-audio-input fix" i had enabled, dissabled for testing and i didnt
enable it again, and there was a recording starting the same time the
drives failed, and not just one went out but 3 out of the 4 went out,
but since they simply went offline and not bad, i was able to recover
with no data lost, any chance that it could be an incompatibly with the
sata_mv libata driver for the chipset:
00:0e.0 IDE interface: nVidia Corporation MCP55 SATA Controller (rev a3)
00:0e.1 IDE interface: nVidia Corporation MCP55 SATA Controller (rev a3)
00:0e.2 IDE interface: nVidia Corporation MCP55 SATA Controller (rev a3)
and ivtv causeing both my drives to fail out and ivtvs bad audio?

attached is the syslog file of the errors outputed pertaining to the
drive failures if its of any use to see if this is the issue, also all
the drives have bin checked to see that they are good drives, and sdc
has bin replaced with a good offline spare i had last time i had a
failure to rule out bad drives.


Thank you so much for any help if this is the cause of both of my issues.

ok, here is the debug reports, i did the fallowing, i got the system to be
producining the bad audio
and generated the log status file, and a debug file, then i used the

brought the audio to being normal, and generated another set of logs and
debug logs
since this is little difference in the log status i am only posting the
diff of the 2, as for the debugs
im not sure what you need so im posting the full log of both and a diff.

I've looked at the diff's.  Some comments are in line below.  Basically
the significant differences are in the audio decoder register block of
the cx28543.  Unfortunately most of the differences are in
undocumented/reserved register regions.

The ones in the AC'97 audio codec register region very likely don't
matter as ivtv and PVR-150's don't use this interface.

The undocumented registers in the range 0x880-0x89f being different tell
me the audio micrcontroller is doing something differently in the two
cases, but that may or may not be the cause of the tinny audio.


please let me know if you need any more information thanks for the help.

The next time you get tinny audio, could you use v4l2-dbg to set
register 0x810 to 1 and then back to 0.  This toggles the SOFT_RESET of
the audio microcontroller, and should get it to try and redetect the
audio standard.  (IIRC the driver does this as one of the steps when
switching inputs.)  If that fixes things, you will have then verified
that the audio microcontroller firmware in the cx25843 is getting
confused.


If that is the case you have some courses of action which are limited
because the firmware source is not available:

1. Experiment with different versions of the Mako (cx2854x) firmware to
see if there is one that doesn't produce the tinny audio problem.
2. Try to reliably detect tinny audio from within a program polling the
ivtv driver, and when you detect the tinny audio condition, run a
utility to reset the audio microcontroller or take some other corrective
action.

3. Since you know the TV standards you normally capture, limit the
auto-detection of audio standard to the one you capture.  I don't think
v4l2-ctl supports this right now, and the driver may not currently
easily support anything other than autodetection of audio standard.
(I'd need to do more research on this.)
