On my Ubuntu 9.04 computer, Audacity functions with the following settings:
Audio I/O:
Playback Device: “ALSA: ALi M5455: ALi M5455 (hw:0,0)”
Recording Device: “ALSA: AK5370 : USB Audio (hw:1,0)”
Recording Channels: 1 (Mono)
Quality:
Sampling – Default Sample Rate: 22050 Hz
Interface:
Display range minimum: meters and ‘Waveform (dB)’: -60 dB (PCM range of 10 bit samples)
Default View Mode: Waveform (db)
I just installed a few files with Synaptic following this sound guide. Interesting tip:
“With jaunty (not sure about intrepid), try this:
pulseaudio –kill
then
sudo alsa reload
It’s worked for me everytime so far, but it has to be done during a user session.”
Good tip, but I won’t try it because Audacity is able to record and Totem is able to play wav files at the moment. But how is it possible to play sound with simon?
Here is another interesting tip. Maybe I should take a closer look at Mint. By the way, this could be an option for the PC that is connected to the video beamer for playing DVDs.
This is my momentary setup of the JACK Audio Connection Kit.
It differs a little bit from my previous setup. My setup isn’t perfect yet, but the numer of x-runs is most of the time in an acceptable manner.
Because I have sound problems under Ubuntu 8.10, I typed into the terminal “sudo nano /boot/grub/menu.lst”. Afterwards, I made a small change, and added “nohz=off”.
title Ubuntu 8.10, kernel 2.6.27-7-generic
root (hd0,0)
kernel /boot/vmlinuz-2.6.27-7-generic root=UUID=bae33ac1-4906-40bc-9924-50fecb63acb0 ro quiet splash nohz=off
initrd /boot/initrd.img-2.6.27-7-generic
quiet
I found this trick here. I hope that it will work out.
Additional remark: I just followed this tutorial. It is for Ubuntu 8.04. I am using Ubuntu 8.10. But I hope that it will help to solve my issues.
November 5, 2008: It didn’t work out. I am still having sound problems. I will try to make a separate installation of Ubuntu on a different hard drive. It was a mistake to upgrade to Ubuntu 8.10 even though some things are better now. It would be better to use two different installations: Ubuntu 8.04 on one hard drive, and a fresh installation of Ubuntu 8.10 on a different hard drive. Never touch a running system. It might get worse.
Sound under Linux is often a big problem. I have solved this problem partially by using the JACK Audio Connection Kit. Here is my configuration:
It looks pretty difficult
I had to try several times to get an acceptable solution. By the way, I am using Audacity in conjunction with JACK.
