Re: [trinity-devel] Latest Build broke ALSA sound (play works - aplay screaches)

11 Feb 2014

...
   This is
getting stranger:

   Darrell, you were correct, aplay will play .wav files just  fine. I rebuilt
  both arts and tdemultimedia - no change. From the
command line,  both 'play' and
  'aplay' work fine, but TDE will not play
any sound. I open  kcontrol -> Sound
  System -> [Test Sound] and I get nothing. I
click the litte |>  next to any sound
  event file - same result, no sound.

   Checking .xsession-errors, each time I try playing the a  sound, I get the
  following:

 unix_connect: can't connect to server

   Checking /tmp/tdesocket-david/localhost.localdomain-02d0- 52f9c6b6, it is there
  and easily accessible, so I don't know what
that unix_connect  error is all
  about. The bottom line, something is active very
differently  with this set of
  package regarding sound. Let me know if you have
any other  thoughts. We'll look
  at this more later.

Just so it is clear. After update from the packages built on 1/29 
to packages
built on 2/8, sound event notifications no longer work in TDE. 
Using play or
aplay from the command line in konsole, both WORK FINE:

02:37 valhalla:~> aplay

  However, as soon as any sound event in TDE is triggered (such as 
on shade), I
get the following dumped into the .xsession-errors file:

  So where is TDE trying to make the call for the sound event 
resulting in the
unix_connect error? 
Yeah, Linux is ready for the desktop....

You have tested sound with the aplay and play commands, which 
validates your hardware and alsa. Start an alternate desktop to at 
least isolate the problem to only Trinity.

I don't know about the above messages, but seems arts is not 
starting or is not loading completely.

Another idea is permissions. I quite often log into my desktop as 
root to test permissions issues. Not tdesu, actually logging in as 
root. I don't prescribe to any aspect of the anti-root religion and 
logging in as root is a quick way to determine whether a problem is 
permissions related.

Also try with a fresh profile. I have a couple of testing accounts 
I use to try various things without touching my normal accounts. 
With the testing accounts often I 'mv ~/.trinity ~/.trinity.bak' 
and then start Trinity. That creates a new ~/.trinity profile 
directory. When I finish testing I 'rm ~/.trinity' and then 'mv 
~/.trinity.bak ~/.trinity'.

With a fresh profile directory you should hear the stupid login 
sound file if arts is loading correctly. This at least narrows the 
issue to your profile or Trinity in general.

When I have arts issues I delete the tdesycoca cache files, 
~/.mcop, and all the Trinity socket and temporary files. This is a 
big reason I don't use graphical logins. I can exit X and be back 
to the command line without worrying that the login manager and X 
are still running. Provides an easy way to debug and delete files.

I also just now remembered there is an arts config file. Once upon 
a time in the KDE3 days that file caused problems with one of the 
options, but I no longer remember the details. Anyway, try renaming 
~/.trinity/share/config/kcmartsrc.

And yeah, the tdemultimedia conversion to cmake never was completed.
