Hi chattrhand
Here's the problem:

no sound found
Playback open error: -2 No such file or directory

For whatever reason, the sound system isn't ready.

# /home/tc/.X.d/autostart
sleep 1
[ $(which flit) ] && flit > ~/flit.txt &
sleep 1
speaker-test -c2 -t wav -l1 &

Try increasing the first sleep command to see if it's timing related.

Is it possible that you have more than one sound device, for example hdmi and analogue, and the default could change on reboot?

For me, if hdmi comes up as default, flit will not find any sound device. If analogue comes up as default, things work fine.

One other thing I have noticed is that if the sound volume is adjusted via flit, it is not saved and reverts to the default volume on reboot.

Wouldn't adding  alsactl store  to  shutdown.sh  fix that?

Hi Juanito

... One other thing I have noticed is that if the sound volume is adjusted via flit, it is not saved and reverts to the default volume on reboot.

I worked out the code for saving and restoring the volume if you are interested. There is one caveat however. I think there's a
truncation error in the volume calculations. Place the mouse cursor over flits speaker symbol and wait for the tool tip to pop up
with the current volume level. Using the mouses scroll wheel, alternate one click up, one click down, one click up, etc. You'll
see the volume level takes larger steps going down than going up. The error gets smaller as the volume level drops. It appears
to be caused by converting 0 to 100 volume levels to the mixers 0 to 31 scale and back again. Set versus read back values
look like this:

Code: [Select]

Set   Read
100    100
 90     87
 80     77
 70     67
 60     58
 50     48
 40     38
 30     29
 20     19
 10      9
  0      0

Using the mouses scroll wheel, alternate one click up, one click down, one click up, etc.

I didn't realise you could do that - this thing is smarter than it looks

flit updated to latest version in tinycore git

[Rich]

Hi Juanito
If you're interested in trying it, I've attached a patch to update flit. Changes are:
1. Sound volume is now saved when you click on  Save configuration.
2. ALSA Audio level calculations rewritten to round instead of truncate.
3. Lowered the volume stepsize to better fit ALSAs 5 bit (0-31) volume level range.

Here are the changes if anyone wants to scroll through them:
