I find that the sound level in a recording is quite soft (compared to watching regular tv outside of Myth). So I usually have to crank up the volume when I watch a recording, and crank it down when I watch regular cable tv (not Myth's "Live TV"). Granted the difference is not a whole lot, but it would be nice if I could make both more similiar.

Is there a way to boost the sound level in a recording? I am using a PVR150, with cable connection to the coaxial input.

I am pretty sure sound level is one of the settings in your Recording Profiles (under TV settings). If you go too high it will distort so play with it a bit.

There is a volume recording level under the recording profiles for each profile (Low Quality, LiveTV, High Quality, etc). This will set the volume level when recording shows.

You can also adjust the playback volume by using the keys listed in the Knoppmyth docs.

[ or F10 decrease volume
] or F11 increase volume

If your Live TV is also similarly soft, sounds like you need to raise the output volume from the Myth box as a whole, rather than just in the recordings?

I also found some volume controls under the Setup --> General page. There are slider controls for "Master Mixer Volume" and "PCM Mixer Volume" as well as the ability to select either PCM or Master as the Mixer. Do these affect the recording sound level?

What is a Mixer anyways, and where do adjusting these volumes take effect?
Mine's currently set to use the PCM Mixer. What is the difference between the PCM and the Master mixer?

Your sound card has multiple sources where it can get noises from. PCM is recorded sound (CD-audio redbook format, .wav, .mp3, .etc.), the other sources like midi and line-in can also generate there own noises that you might what to hear. Without the mixer you could only ever listen to one source at a time. So no mixing sources without a mixer.

The master setting in the mixer controls the entire outputfrom all the sources. Where as the PCM setting only controls the PCM output and leaves all the other settings alone.

Most likely you will only ever use PCM sound with your computer.

What tuner card do you use? Hauppauge cards are known to have lots of variation in their audio level. One of my cards in noticably quieter then the other.

Thanks ryanpatterson.

I use a Hauppauge PVR150. My current setting is to use the PCM mixer.

So if I understand you correctly, PCM affects the coaxial cable-in connection on the card. Now, since the PVR150 also has an audio line-in (I'm assuming to be used in conjunction with the svideo-in port), then if I have anything connected there, I'll need to change the mixer to "Master"?

Those are for playback. For recording you need to look elsewhere as previously indicated. From the main menu You need to go into utilities/setup->setup->TV settings->recording profiles and make sure that the level in each profile is correct (I wouldn't go over 90%).

I have a PVR-350 and after upgrading to R5E50 from R5A30 the volume overall is very, very quiet. I have the volume in the alsa mixer and in the setup screen cranked all the way and it is still very quiet. The volume was normal before the upgrade. Is there anywhere else I can look to increase the volume level?

Search for other postings by me that mention audio/sound level or capture volume. I made one that covers all the possibilities within the last several months...

I had the volume up to normal levels after running some v412-ctl commands I found in another post, but now after my system crashed I can't get sound from live TV and newly recorded programs again (previously recorded shows play fine). I have run alsaconfig and gone through alsamixer and neither seem to have an effect on the sound. One thing that does seem to stand out is I cannot get the volume control to appear on screen while watching TV. I have used both the [] and function keys and still nothing. In my settings I am using the internal volume controls, and there is no sound form my motherboard on-board sound either.

Help!
