Sound is very high pitched

Gamezace · 11-04-2004, 12:18 PM

Well I got my sound all up and running with ALSA - and started playing some music off of my windows partition...and noticed something interesting.

All the pitches are sky high. The guitars sound like banjos. Mark from Blink 182 sounds like Tom. And techno sounds like it was made with those lose chinese strum-things.

How would I go about fixing the pitch settings for my machine? And if its just an equalizer problem, which I'm sure some of you will suspect, what Hz should I fix? I have toyed with it for hours, and I can't seem to find the right settings (if that indeed, is the problem).

Any ideas?

Thanks!

there's something wrong with sample rate
please post your asound.conf

I don't seem to have that file...

that's not so bad
try mine
create a file in /etc/asound.conf (as a superuser) and paste this

pcm.my_card {
type hw
card 0
mmap_emulation true
}

pcm.dmixed {
type dmix
# any unique number here
ipc_key 313
slave {
pcm "hw:0,0"
# these settings may require tweaking for different sound
# cards; this is for the Powerbook's built-in snd-powermac
# probably not required at all for well-behaved cards...
# period_time 0
# period_size 1024
# buffer_size 8192
# mentioning rate fixes wrong speed/pitch in native ALSA stuff
rate 44100
}
}

ctl.asymed {
type hw
card 0
}

pcm.dsnooped {
type dsnoop
ipc_key 2048
slave {
pcm "my_card"
# rate 48000
# period_size 128
}
}

pcm.asymed {
type asym
playback.pcm "dmixed"
capture.pcm "dsnooped"
}

pcm.pasymed {
type plug
slave.pcm "asymed"
}

pcm.dsp0 {
type plug
slave.pcm "asymed"
}

pcm.!default {
type plug
slave.pcm "asymed"
}

ctl.mixer0 {
type hw
card 0
}

ctl.!default {
type hw
card 0
}

Alright, I created the file. Don't I have to set my drivers to use it now or something? How do I go about that?

Thanks!

Can you followup as to what I do with that code?

leadazide · 11-05-2004, 08:06 AM

/etc/asound.conf is a global configuration file for ALSA library. It will be detected automatically, you don't have to restart sound. Just create file and save it.

It enables Dmix software mixing plugin on output 0
(if you have creative live! or better sound card you can replace 'type dmix' with 'type hw <enter> card 0' and remove all dmix/dsnoop/asym stuff

pcm.dmixed {
type dmix
# any unique number here
ipc_key 313
slave {
pcm "hw:0,0"
# these settings may require tweaking for different sound
# cards; this is for the Powerbook's built-in snd-powermac
# probably not required at all for well-behaved cards...
# period_time 0
# period_size 1024
# buffer_size 8192
# mentioning rate fixes wrong speed/pitch in native ALSA stuff
rate 44100
}
}

Take a look on the last two lines - this should fix the pitch problems.

Hm, alright - well I have created the /etc/asound.conf file, and pasted in the code above. Unfortunatly, I am still having the same problem.

Any other ideas?

leadazide · 11-06-2004, 10:10 AM

pcm.!default {
type plug
slave.pcm "asymed"

--> try to paste here
rate 44100
}

if it doesn't work, try rate 48000 (change it in pcm.dmixed and here)

You, my friend, are a genius. Thank you so much!

Edit: That means it worked.
