low audio output

[mark467]

why is the audio from tv and dvd so low on all my mythbuntu boxes and mp3 are really loud. i am constantly having to turn my volume up and down when switching back and forth. is there a way to correct this

[Archmage]

Did you incresse the volum within Mythtv? I think F11 or F12 is the correct key.

that makes everything louder. my problem is mp3's are a lot louder than tv & Movies when i switch back and forth without changing volume

Can you describe you audio setup (analog out, spdif passthrough, to audio receiver or TV speakers, etc.)? There are a lot of different variables, and in many cases the source files have different audio levels (it's really annoying when I am watching a station live and then it goes to commercial. The commercials are almost always noticeably louder than the show).

Also you may want to try changing volume levels of different controls in alsamixer.

Ok my forntend has basic onboard audio (analog out to tv via 1/8 mini to rca) and my frontend/backend has a SB64 card (analog out via 1/8 mini to rca to surround sound amp) the both have the same issue. When playing tv recordings or dvd's i have to turn the tv or srs amp way up almost to max, mp3 are loud enough at normal listening lvls.
Example on fe w/ tv: reg cable tv vol 13, regular dvd player vol 13, fe mp3 vol 13, fe dvd or recorded tv vol 38

At first i thought it was line in vol for recording tv but it does it with dvd iso's also. If I max out the line in it is still not as loud but gets distorted from to much gain.

Hmmm.. Do you have the same problem if you play your recordings/dvd outside of myth with mplayer or VLC? This may help determine if it is the source or myth or...

How do you record your tv signals (what type of signal are you capturing/tuning)?

I just noticed a similar problem on a new myth set-up, I'm not sure about mp3's being louder, but I need to have my reciever up very near max to get resonable volume.

Right now I'm using onboard sound, analog stereo 1/8" to RCA to my reciever. Defaults setting in myth, except volume up to "90".
Sound is coming from a Biostar AM2 MB, nforce chipset.

I will investigate the sound level at other times and post later. I also want to see if running digital over analog makes a difference, but it might be the weekend before I get to that.

anyone have any ideas on this. as stated above...

audio receiver volume needs to be up really high for videos and recordings to be heard.
mp3's play at a normal lvl like all my other equipment.

1/8th mini to rca for audio (sony surround receiver)

in alsamixer all the bars are set to 90's

As stupid as this might sound, did any of you go into the sound control under XFCE and change the PCM and Master to 100%?

[mark467]

I am not familiar with that. what and where is it?

You can open up a terminal window and run

xfce4-mixer

which is very similar to the

alsamixer

progrm and the alsamixer GUI you can get to in the multimedia menu.

I'm having the same "low volume" issue. I've got to turn just about everything to 100%--TV, PCM, Master, Front, etc--MythTV's volume has no effect, I've just realized.

Go to the panel, and add volume control. Right click on it, and there should be a preferences. Choose Master, crank up to at least 90%, and choose PCM to do the same. That seems to take care of it for most people who have asked me about this. It is a pretty common *buntu problem with ALSA and PulseAudio updates.

[mark467]

Thanks I will try that and let you know.

Any resolution on this? I have tried several different setting for the audio, jacked up everything in xfce and still have to turn up the tv and amp volume way to high (so high I hear buzzing).

Sounds like you've got the cable in the wrong place. (At least, that's what it means when I just get a buzzing.)
