Re: [gentoo-user] WinXP under VMWare: no sound
Richard Fish: Unfortunately, even though I can get all the right libraries to load, I cannot get sound to work reliably on amd64. Neither aoss nor vmdsp seem to work for me, either as a user or root. That's very strange, because... However, I think I know how to make aoss work as a normal user on your system. You should just need to: # chmod 4755 /emul/linux/x86/usr/lib/libaoss.so.0.0.0 # ln -s /emul/linux/x86/usr/lib/libaoss.so /usr/lib32/libaoss.so The first command is just to make sure the library is setuid. YOU ARE GREAT!!! I have too Gentoos, stable and testing. I had only vmplayer installed in stable (the virtual machine is in another partition). So I have: a) emerged alsa-oss b) emerged emul-linux-x86-soundlibs c) chmoded and ln -sed as you have advised and sound is working now both as root and as normal user! Thanks! If you have some spare time, I'ld like to understand why the symbolic link in /usr/lib32 is needed (and why your solution works on my system and not on yours). But don't bother. I can imagine that you have something better to do ;-) Tanks again Sergio -- gentoo-user@gentoo.org mailing list

Actually, no. You have to use the library name, so libaoss.so is valid, /emul/.../libaoss.so is not. However, the search path in this case is pretty limited. I had to make a symlink from /usr/lib32/libaoss.so to /emul/linux/x86/usr/lib/libaoss.so to get aoss to preload as a normal user. Are you sure that that has not been reverted in glibc 2.4-r3? Well I'm glibc-2.5 on both amd64 and x86, so I can't say for certain what happens with 2.4, but yes, I believe it was dropped in all sane versions of glibc. In particular, none of my tests today on amd64 or x86 revealed any significant problem in actually preloading the libraries (other than the symlink issue I noted above, and of course, needing to chmod 4755 the library to be preloaded). FYI, I also reported the preloading problem via bugzilla way back when: http://bugs.gentoo.org/show_bug.cgi?id=86844 I'm going to try installing workstation on my amd64 desktop and see what I get.

For vmdsp, my best guess is that a 64-bit artsd won't communicate with 32-bit clients. But that is just a guess. FYI, on my x86 laptop both vmdsp and aoss work, although aoss produces choppy audio.

If this file doesn't exist, then *that* is why preloading doesn't
work. If instead you have emul/.../libaoss.so.0.0.0, then change
the LD_PRELOAD in aoss32 to:
LD_PRELOAD=${exec_prefix}/lib/libaoss.so.0.0.0${LD_PRELOAD:+:$LD_PRELOAD}
I would also add an echo for debugging after that:

i) I can't understand why root can't open /dev/dsp when running
vmwarearts. I can only guess that aoss works better ;-)
Since preloading appears to work in this case (no error from that), I
am going to assume that this is actually a failure to contact artsd as
root. Note that the effect of preloading is to fool vmware into
contacting artsd instead of opening /dev/dsp...so the error can
actually be slightly misreported.
Are you actually logged into KDE as root, or as your normal user?
What happens when you run artsplay

This is a shell script (your clue is the size). The actual binary
that executes the virtual machine (and this needs to produce sound) is
in /opt/vmware/workstation/lib/bin, and is named vmware-vmx. It is
almost certainly setuid.
(BTW, I should have said vmware _uses_ setuid executables)
my vmware *is not* setuid!
However, nothing changes if I do chmod +s on libaoss *and* vmware:
No, don't make the shell script setuid. That would be a security hole.
sound only works when I am root, otherwise libaoss is not preloaded.
I really don't understand why aoss would only work as root. I suspect
a path or environment issue here, possibly a different library is
actually being loaded. I suspect this has more to do with the actual
path to the library being loaded as root versus your user account.

On Marc 27th, 2005 you wrote in a VMWare Forum:
Ok, I got it figured out. It seems that in response to GLSA
200408-16, Gentoo made a patch that in addition to fixing the
LD_DEBUG vulnerability, moved the cleansing of the environment
to before the values were saved. This part of the change is not in
the official glibc CVS source, and the patch is not applied for
glibc-2.3.4.20050125-r1 (currently marked for testing...).
So Gentoo users will need to upgrade their glibc to at least
2.3.4.20050125 to use LD_PRELOAD with setuid binaries.
Are you sure that that has not been reverted in glibc 2.4-r3?
I'm going to try installing workstation on my amd64 desktop and see
what I get.

Re: [gentoo-user] WinXP under VMWare: no sound
Richard Fish: The workaround to this is to use a wrapper such as aoss or vmware-dsp that fakes out the application when it tries to open /dev/dsp and uses another audio API instead (alsa for aoss, esd or artsd for vmware-dsp). Since vmware-dsp (which is ~amd64) doesn't compile, I have: - emerged alsa-oss - chmod +s /usr/lib/libaoss.so.* - created a script: #!/bin/bash LD_PRELOAD=libaoss.so exec /opt/vmware/workstation/bin/vmware Now: i) if I run the script as myself, sound doesn't work and I get ERROR: ld.so: object 'libaoss.so' from LD_PRELOAD cannot be preloaded: ignored. I get the same result if I run aoss vmware. As to ldd /usr/lib/libaoss.so.0.0.0: libalsatoss.so.0 = /usr/lib/libalsatoss.so.0 (0x2b09ff97f000) libc.so.6 = /lib/libc.so.6 (0x2b09ffa89000) libasound.so.2 = /usr/lib/libasound.so.2 (0x2b09ffcb4000) libm.so.6 = /lib/libm.so.6 (0x2b09ffe8b000) libdl.so.2 = /lib/libdl.so.2 (0x2b09fffe) libpthread.so.0 = /lib/libpthread.so.0 (0x2b0a000e4000) /lib64/ld-linux-x86-64.so.2 (0x4000) ii) if I run the script as root, sound works! So, it looks like a matter of permissions, but I can't guess what I should change. I hope that you can ;-) Cheers Sergio -- gentoo-user@gentoo.org mailing list
