[mythtv-users] hd-pvr problem recording audio after firmware update

Hello All,

I was having problems with my hd-pvr's recordings (it would have
breaks in the recordings causing it to miss 30 seconds or so every so
often).  So I decided to update the firmware to see if that would fix
the problem.  The good news is that I no longer have that problem.
That bad news is that now the audio will randomly not work when
recording (it worked without a problem before).  Usually it will
record fine for a couple shows, and then when it stops working it
won't work for any more recordings until I restart mythbackend.  I
tested recording on my Mac (with EyeTV) and had no problem with the
audio, so I know it's not a hardware problem.

The one odd thing I noticed about the recordings is that the ones that
don't work say they are aac.  I have SPDIF chosen as the input and all
the recording profiles say AC3 for the audio format.  I have tried all
of the recording profiles and the problem happens with all of them.  I
even tried creating a new recording profile, just to test, but it
doesn't show up in the front end as an option (which I guess it
another problem but not that important).

I tried updating to the latest version of Ubuntu (10.04) and MythTV
(0.23) to see if that would fix it, but I still get the same problem.

I don't know if it's needed, but here's the dmesg output:

[59281.690062] usb 1-5: new high speed USB device using ehci_hcd and address 7
[59281.868016] usb 1-5: configuration #1 chosen from 1 choice

driver might not work
[59282.380416] hdpvr 1-5:1.0: device now attached to /dev/video0

and here's the modinfo:

Thanks for any help.
