[gentoo-user] No sound from audacity...

[tuxic]

Hi,

got a strange problem with audacity:
I did:
Load a *.wav file into audacity (it contains sound as visible in audacity 
Menu->Select->Select all
Press play bottom

Nothing

This is printed on the console:

Expression 'framesAvail' failed in '/var/tmp/portage/media-libs/portaudio-19.06.00-r3/work/portaudio/src/hostapi/alsa/pa_linux_alsa.c', line: 3625

My installation is:


[I] media-sound/audacity

     Homepage:            https://web.audacityteam.org/

Playback works fine using mpv, Firefox, etc...only audacity has a
problem.

Is it hardwired to pulseaudio?

Cheers!

First I thought about not responding here but decided otherwise. May I
ask you first if you did a basic search about this issue before posting
here?

If I look for "'PaAlsaStreamComponent_GetAvailableFrames( self,
&framesAvail, xrun )' failed" the first result is a link to the Gentoo
forum [1] which suggests the installation of alsa-oss to fix this issue.

So did you look for the issue and put some effort into it before posting
here? No offense but you post a lot of questions about problems you have
here which in my opinion are often solved with little effort you could
have done yourself. So the thought pops up that you are just lazy and
let others do the work. Also I only every see you asking questions but
never trying to answer questions of others.

Explaining your problem and also stating what you already tried or where
you have looked for a solution will avoid that people get that
impressions and they may be more helpful. Or the post is completely
unnecessary because you solved it yourself after 5 minutes of
investigation which saves the time of all the other list participants.

Just a friendly recommendation from me as over time this annoys me a
little and probably I am not the only one here. If people are annoyed it
is unlikely for them to help. So help yourself to make others help you.

To play devil's advocate, and at the risk of going off-topic straight 
away, a person who has a lot of issues/questions is going to be less 
likely to be confident and knowledgeable enough to answer someone else's 
question.  They'll be more likely to defer to more experienced readers.

I have about 7 years of daily Gentoo use under my belt and I'm still not 
confident enough to answer a lot of the questions on this list without 
some research and testing on my own, which time does not always permit.

You make good, valid points otherwise.  Just wanted to share that 
internet stage-fright and imposter syndrome are both alive and well.

All true! And it is no problem if the help is one sided, but on the other hand there are always low hanging fruits!
