Setting Correct Audio-Device

[Razor_109]

Hello,

I'm quite the linux-newby but i got XBMC working properly..

Did it from building latest SVN and got my remote and VFD from Antec Fusion working.

But now i still got one 'problem'...

My sound is ok, but it is a little soft.. i mean.. i have to turn my reciever up all the way.

I'm using the Analog out since my reciever doesnt accept any digital.. (next point of upgrade ;) )

Now i was searching the audio settings and saw:

Audio Output Device --> Default

Is this correct? or do i need to set another name? would it even make a difference to the sound level?

PS.

I cant seem to find the audio mixer in Ubuntu where i can higher the volumes, but i have maximized the audio in ubuntu desktop so unless there is some 'Master' Slider of some kind i can slide up.. i dont know where to look.

Sorry for the 2nd reply...

but i noticed something else..

When i'm starting a video i'm dropping LOTS of frames, but no Videoframes because sometimes only the audio stutters.. video goes perfect..

for example running 720p @ 20% for both cores.. i think something is wrong with my audio device :)

no idea what..

Try bumping up the levels in alsamixer, messing with the device isn't going to change the volume.

Dropped frames at the beginning of a video can be expected and generally aren't a problem.

ok found out how to acces the Alsamixer and i bumped up the levels.. works like a charm now.. thanks!

Only still the dropping frames.. how many +/- is normal? i sometimes drop like 200 - 400 frames.. but i dont notice anything in the video.. just audio is sometimes out of sync in start.. just for couple of seconds..

I got 1 videofile, mkv 720p keep dropping frames.. and start stuttering while the 1080p mkv's play nicely.

I'm running on a E8400 and the CPU never hits more than 40 - 50% playing HD Content so i dont think its the cpu... as i should notice the video dropping frames too then.

Well i'll go and play/try more.. maybe i get some clues ;)

Hi Razor.

Wondering - you are using analogue 5.1 surround sound? Have you tried playing 5.1 DVDs - do they work okay for you?

Disregard this post if you're not using 5.1!

[Razor_109]

heey no i'm just using 2.0 out..

gonna try hook up my 5.1 set and i'll let you know then.

Rikbrown: could you post your asoundrc?

trying to enable the 5.1 channels..
