The cat meow is jumpy, as if the buffers aren't quite big enough or something. Probably a more general issue...

Triage. Reproduced on os54. Method:

  • start Scratch activity,
  • click on the Sound button on the top left collection of eight buttons,
  • drag a "play sound [ meow ]" directive from the bottom left area to the second bottom left area that has the tab label Scripts, a copy will be placed in the Scripts area,
  • double click on the copy of the directive, and the meow sound is played, and it is scratchy.

Ticket moved out of 1.5-software-final to 1.5-software-update as a result of a software manufacturing release triage meeting. Per ed, dsd, cjb, reuben, quozl.

Looks like an underlying squeak problem to me. Etoys shows the same symptoms. To reproduce:

  • Start Etoys
  • Click on Supplies -> Object Catalog -> Multimedia -> PianoKeyboard
  • Press any key on the keyboard for a long time

ALSA plugin with fix for freezing and sayamindu fix for scratchy sound

Changed 3 years ago by dmoco

Looks like keeping several versions of the VM source around has come back to bite me in the ass. Apologies to those testing my changes to do with freezing last month and finding sound playback was scratchy. I had convinced myself the source included Sayamindu's patch but it did not. Amended source for vm-sound-ALSA attached.

Raising to blocker so that we don't forget to take a fix for this.

Tested in os204 installed using fs-update, the meow sound is no longer jumpy, interrupted, or scratchy.

(Using olpc-update and Software update does not fix the issue, since there was no change to the activity version.)
