Subject: [linux-dvb] pctv 800i almost working.
Date: Fri, 02 Jan 2009 12:23:08 -0700	[thread overview]
Message-ID: <495E699C.10002@mho.com> (raw)

Hi

I tried to get my pctv 800i card working on Ubuntu 8.04.  But after 
reading that the best solution was to install a new generic kernel, I 
decided to wait until Intrepid (8.10) came out.  After installing 8.10, 
I loaded the firmware as recommended on mythtv wiki and was excited to 
see a sharp analogue picture. But, no audio.  Audio works on all other 
applications.  Knowing what to try to fix it is well beyond my linux 
knowledge. I figured there are many tuner experts on this list that 
might help. No help from mythtv or ubuntu lists.

----------------------------------------
dmesg is full of this:

   38.529786] cx88[0]: irq aud [0x1001] dn_risci1* dn_sync*

What's with the three occurrences of cx88 on 17?

Anything I can try?
