Bug 274339 – app-emulation/vmware-workstation directly uses oss. meaning 2 oss applications cannot share sound device

• Product: Gentoo Linux
• Status: RESOLVED WONTFIX

[Description Alexander Bezrukov 2009-06-16 13:01:12 UTC]

Hi,

app-emulation/vmware-workstation (all versions) directly uses oss layer meaning that two oss-enabled application cannot share the sound device. From the end users' perspective this manifests as "Device or resource busy: /dev/dsp" and no sound in virtual machines whenever one is trying to run another oss-enabled application (e.g. viewing a web page which contains some flash with firefox+www-plugins/adobe-flash).

A quick fix (which works for me for a long time already) would preload libaoss.so (provided by media-libs/alsa-oss, which should then be added to dependencies, perhaps conditionally) and thus re-route all calls to /dev/dsp through alsa devices (provided alsa is setup correctly for this purpose which is now default). My request is to add this simple fix to vmware-workstation ebuild so that more people can benefit from it (and those who already do wouldn't need to apply it more and more as the package files get overwritten because of updates).

Since the ebuild is rather complicated and I am not sure about the right paths, attached is just the /opt/vmware/workstation/lib/vmware/bin/launcher.sh file not a patch. Diff is only 1 line:

@@ -313 +313 @@
-      exec "$binary" "$@"
+      exec /usr/bin/aoss "$binary" "$@"

Could you consider adding this to the ebuild?

Thanks.


Reproducible: Always

Steps to Reproduce:
1. Run a virtual machine
2. Open a youtube.com video in firefox+xulrunner+www-plugins/adobe-flash
3. Stop video (without closing firefox) and try to play some music in the virtual machine.

Actual Results:  
Device or resource busy: /dev/dsp

Expected Results:  
Sound gets mixed.

Fixed launcher.sh

vmware workstation/player 7.x uses alsa. Should't be a problem any more.
