Hi, Bert. Re: Tried sound playback in Scratch, it's choppy, many clicks to hear. Suspended fine, resumed playing sound. Recording does not freeze the activity, but has bad quality. Derek says that the recorded sound is actually okay if you export it and play it with a good sound player. Does that fit with your experience?

Re: F11-for-XO1.5 Release 10.1.1 Release Candidate 2
Hi, Bert and Derek. Derek just send me the combined version. I tested playback and recording on the XO 1.5 and it was perfect. Hooray! I did NOT test to verify that it survives suspect resume, as Derek's previous version did. Hopefully someone else has verified that. It sounds as though this fixed version of the ALSA plugin will get into the XO Squeak VM package. In that case, should I omit it from the next version of Scratch? (A new version of XO Scratch is coming soon to include the Lego WeDo plugin which Derek just finished.)

Hi, Which source tree root are you referring to? The sources for the current Fedora package. A source rpm has a tarball of the sources, and optionally a series of patch files relative to that upstream tarball. Not sure where to find those sources though, I'm not too familiar with Fedora procedures. Here's the latest build: http://koji.fedoraproject.org/koji/buildinfo?buildID=148721 The .src.rpm contains a specfile (that describes which patches to apply on the tarball) and the tarball and patches. If you want to unpack the .src.rpm on a machine that isn't running Fedora, I think you'll need rpm2cpio and cpio: rpm2cpio squeak-vm-3.10.5-2.fc11.src.rpm | cpio -idmv Thanks, - Chris. -- Chris Ball c...@laptop.org One Laptop Per Child ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Someone would need to rebuild Fedora's squeak-vm-3.10-5 package with Derek's
patched sqUnixSoundALSA.c file (attached to the forwarded msg below). The etoys
package is unaffected.
I'm happy to apply a patch to the etoys package in Fedora if someone
can provide me a patch rather than a complete new source file.
