<pre wrap="">I initially set up this box just with a hauppauge pvr-500 (analog), and got
everything set up. I added a Hauppauge hvr-1800 and the digital tuner seems
to be working fine, except the audio on the recordings is VERY quiet. I
opened some files recorded off the analog and digital tuners in VLC and
Mplayer and the differences are persistent across playback programs (though
myth playback is similar to the other programs' volumes under 20%, even with
the volume maxed out in myth... combining these two things, getting loud
enough audio watching my digital recordings is difficult). The problem
exists with liveTV and after recordings have been transcoded with the audio
transcoded to mp3. The difference is also apparent when playing the files of
the recordings from my windows laptop. Any ideas on how to fix this
disparity? I haven't found anything googling (probably since it is a new
card). Is there maybe some way to turn up the volume in the drivers for the
card?
Thank you,

>From what I've heard, and i'm no audio expert, the problem comes from
the way the stations are compressing the audio before sending out the
signal. By compressing the audio into a smaller volume range they can
reduce the bandwidth required to send out the signal, but this seems
to result in lower volume at least on equipment that doesn't
compensate for it. This also happens to me on my HDHomerun, and I
don't know how to fix it.

Again, imho it is the digital that is correct. It there is any
compression going on to save bandwidth, it is in the analog signals.
The digital tuners are passive in that they don't decode-process-encode
the audio. They just pass it through. <br>
<br>
Is there a way to turn down the analog tuners audio? That would make
them the same. Remember that joke about the guy who was blind in one
eye and asked God to make both his eyes the same?<br>
