Ubuntu 8.04 sound

[texas.chef94]

I am new to linux, but have used audacity in windows for some time, but effective setup in ubuntu seems to elude me.
I have posted my concern to linux forum and still having same concerns.
I downloaded audacity with no problems choose alsa, In SPM went to search, choose alsa (maybe too many packages) I have packaged alsa base-alsa-oss and alsa-utils and this might be a conflict.
In audacity I went to generate+noise+play and infact sound was loud and clear.
Tried my mike a Samson CO1U and recorded, but no playback and on record the display led me to believe It was not working.
Searched around for means of configuring mike and came accros gnome-volume-control so put that in monitor out of desperation and lo and behold there was an option for Samson CO1U (alsa) so I checked it
Ok folks I am floundering as you can no doubt detect.
Please rescue me and thanks

I tried the first command line and received no such file. Out of desperation tried the second even though I felt install was not a concern. Received the same no such file.
Just to clarify I have 1.3.4.-Beta
At this point I am suspecting it might be a beta thing, but tried one other option to give the team a true picture. I went out and captured sound bite you have mail, imported it into audacity and it played loud and clear. So it is either a Beta thing which I doubt or a mike configuration thing which seems likely.
Ready to try anything and thanks

I thought mine was broken, too, but as it turned out, there were some Ubuntu issues standing in the way. Two of them, actually. The first is pretty well documented and at this point not fixed, only worked around: There are issues with pulse-audio and flash in Firefox 3. I found that if I had Firefox open and had run a flash video in it, even if the tab was now closed, Audacity got no sound. Also, if I had Audacious (Winamp-like player) open, it also prevented me from getting sound in Audacity, no matter which driver combination I used in Audacity and Audacious. Once I closed Firefox and Audacious, I just used the alsa-default and had no further problems. I also have the Intel on-board sound.

PulseAudio caused problems for every Ubuntu version I've had (starting with 7.10). It does not like my M-Audio 2496. I disabled PA by adding a "killall pulseaudio" command to the Startup Programs tab in System>Preferences>Sessions. ALSA is the default now and I've had zero problems with Amarok, Audacity, Flash (and other embedded audio) ... etc.

Hi All,
I've been blundering around the Ubuntu, Linux, Audacity forums looking for a solution to my audio problems in 8.04.
Short story
I can't hear playback sound in Audacity even though output level meter is indicating sound.
Long story
When I found this thread I was sure I'd found the solution. Alas, no such luck. I removed pulseaudio from startup, rebooted and started audacity with no other programs running - still no playback sound in Audacity, although killing pulseaudio seems to have fixed some playback problems in other audio applications. Playing flash audio (youtube) in Firefox doesn't seem to cause any problems.
My problems started when I was copying my vinyl treasures to MP3 using Audacity. I'm pretty sure it's not an Audacity problem because I noticed several other audio problems when investigating the Audacity problems.

I have Ubuntu 8.04 installed
I have a gigabyte 965p DS3 motherboard with Realtek ALC888 chip onboard (Intel HDA)
I'm using Audacity 1.3.4-beta with PortAudio v19

Here is the current state of Audio
system sounds - OK
internet sound - OK (youtube audio)
line in - OK (vinyl, cassettes and radio from my 80's Marantz sound system)
MP3 Playback, MPlayer - OK, worked before and after killing pulseaudio.
MP3 Playback, Totem movie player - OK after killing pulseaudio
MP3 Playback, Rythmbox - OK after killing pulseaudio
Audio CD playback, RhythmBox - OK
Playback, Audacity- no sound, even after killing pulseaudio
Record, Audacity- OK, I can hear it while recording from line in, but can't playback anything in Audacity so have to wait until I export to MP3 and play back in other application

So, I have 2 problems
1. no playback sound in Audacity - minor problem - any suggestions?
2. I don't have clue how audio works in Ubuntu / Audacity - major problem! - can anyone point me to an audio 101 tutorial? I've read all the Audacity tutorials and heaps of other info on a variety of forums but am still confused about ALSA, OSS, all the different mixer options and most of the settings in Ubuntu / Audacity audio config. All I want to do is listen to Pink Floyd and my other LPs on my computer and my Axim PDA which I user as my iPod! I'll probably get there eventually, but any help from you audio gurus out there will be greatly appreciated.

2. I don't have clue how audio works in Ubuntu / Audacity - major problem!

And a problem that is well known to Linux users.
The problem is that sound card manufacturers do not create drivers for Linux, so we have to use generic drivers and a general purpose interface.

The old sound system in Linux was "OSS" (Open Sound System). This is still in use and will support basic functionality for a lot of audio hardware and software, though it is not very efficient. OSS has now been largely superseded by "ALSA" (Advanced Linux Sound Architecture) which provides a fast, flexible and powerful sound system with support for a huge range of sound-cards.

There is also "jackd", which is an even more advanced system which provides exceptional flexibility and performance for music application, but unfortunately there are a load of issues that prevent it from working correctly with Audacity, so we will forget about jackd for now.

Audacity will usually run best using ALSA. If you open Audacity then from the "Edit" menu select "Preferences". Look in the "Audio I/O" tab and you will see drop down boxes for selecting the "playback" and "recording" devices. If available you should select "Alsa (default)". If Alsa (default) is not listed, then go to the "Help" menu and select "Audio Device Info" and (copy and paste) let me know what that says.

So, assuming that you have ALSA selected, you now need to open up your computer mixer application. There is probably a loudspeaker icon on one of your desktop panels. If not, then you can open the alsa mixer from a terminal window (try typing "alsamixer -c 0" without quotes into a terminal window).

Finding exactly the right sliders to adjust is a pain - as mentioned before, the ALSA mixer is a general purpose interface, so it will probably take a lot of trial and error to find the correct settings. When you find settings that work - write them down on paper.
