Gentoo 64 bit - SecondLife 32 bit & Voice Audio [SOLVED]

[HeXiLeD]

Hello guys

I am having some strange problems with second life (pre compiled) and audio chat.
Basicly what happens is:

I can hear and play or sorts of sound but not audio voice chat. I have set all the voice options preferences properly and even had some help with it to see if it was improperly set.

For some reason, if i click on "active speakers" to see who is using voice chat at the moment; i cant get the list of the speakers as well as to click on the volume bar there or main speaker to mute or unmute.

Most help i have seen is for ubuntu and it doesnt help me. (so far)

Second Life version.
Linux i686 (Beta) 1.19.0.5

Sould i compile from source? is this a second life linux client issue with gentoo ?

Any thoughts ?

Thanks in advance

edit:
i found this

Could you check and see if the following file exists and post the content (if any):

~/Library/Logs/Vivox/siplog.txt

I also have problems with the voice component of the Second Life client (1.19.0/1) and I have a feeling that we may be encountering the same issue.

If my hunch is correct then you should find mention of an out_of_range exception being thrown by basic_string::substr in siplog.txt. Just make sure you don't check the log after verifying the information below and running the SLVoice binary directly, the error only occurs when the Second Life client attempts to communicate with the running process of the SLVoice component.

P.S. The SLVoice executable requires access to the shared libraries located within the lib directory of the client directory hierarchy; this is the reason you received an error. When running the client the LD_LIBRARY_PATH environmental variable is defined with the location to the aforementioned directory. You can verify this yourself by running 'LD_LIBRARY_PATH=./lib ./SLVoice' within the appropriate directory.

Yup. out_of range

I found a guy on second life with linux and he has it all working properly.
(using linuxmint | www.linuxmint.com )

I told me to get this version:
Linux i686: 1.19.1.1 (Beta) (55 MB)

http://secondlife.com/community/downloads-optional.php

After running it at least now i get more devices shown under voice chat settings.
He told me use ONLY alsa and make sure that SL only uses ALSA.

I still have a few errors and audio is not playing. but al least now there has been some progress.

I have too sound cards:
Creative Labs SB Audigy (rev 03) and Intel High Definition Audio Controller (rev 04)

Q: What sound card do you have ?

Currently the errors that i am having are :

OK, some more information hot off the press. Playing around with gdb it seems the problem lies (not surprisingly) in libvivoxsdk.so, more specifically the oscommon2::SplitNameValueFile() function called by oscommon2::MachineInfo::MachineInfo(). The name of these functions ties up nicely with what I was seeing when using strace, with some of the last system calls being to open and read from /proc/cpuinfo. Despite all this information I fear I'm not much closer to pinpointing the exact problem.

I'm starting to wonder if there's something unique about the format our /proc/cpuinfo files that the function doesn't anticipate and "trips" over. I'm assuming the SplitNameValueFile() function reads /proc/cpuinfo and splits it into name value pairs (i.e. either side of the colon, name: vendor_id, value: GenuineIntel).

If you could post the output of `cat /proc/cpuinfo` that might be of some use to me.

[HeXiLeD]

Thanks for your detailed information. You have done way better than me.
If you need any more specs about my system just click on "My system hardware and software SPECIFICATIONS"
I have everything there in detail.

Could someone update the secondlife ebuild in layman? At the moment its 1.18.4.3. The actual version is 1.19.0.5

Thanks

[Jimeh]

I've got it working (verified in world that people can hear me), I'll post more details shortly. Sorry to be such a tease but I've got some guests round right now.

[Jimeh]

OK, here it is, first a little background.

As I mentioned previously... I had discovered that the Vivox daemon was throwing an out_of_range exception when attempting to parse the contents of /proc/cpuinfo into name / value pairs.

I had come to this conclusion after observing system calls to open and read the aforementioned file, as well as a backtrace which indicated the call to substr (the origin of the exception) originated in the function SplitNameValueFile which in turn was called by MachineInfo::MachineInfo() within the libvivoxsdk.so library. It dawned on me that the problem must surely lie with the format of /proc/cpuinfo; or more correctly, libvivoxsdk.so's poor handling of it.

I decided that the easiest way to test this hypothesis was to remove lines that I suspected would be the cause of the problem. To do this I opened libvivoxsdk.so in vim -b (binary mode), searched for the string representing the path to cpuinfo and replaced it to point to a copy of /proc/cpuinfo I could easily modify.

The problem turned out to lie with the first occurrence of: 'power management:'. It would appear that SplitNameValueFile expects at least a single character between the colon and the subsequent newline. When I modified my custom /proc/cpuinfo file to discard or modify the line to include a space after the colon the daemon ran flawlessly and I had full access to voice in the 1.19.0 and 1.19.1 clients.

I have provided a small bash script that when executed within the lib directory of the Second Life client directory hierarchy will do the following:

1. Write a copy of your /proc/cpuinfo file to the current directory with a space appended to each colon that appears at the end of the line.
   
2. Backup your current libvivoxsdk.so file to libvivoxsdk.so.bak.
   
3. Modify libvivoxsdk.so to point to the newly created copy of cpuinfo (from the perspective of the SLVoice binary, i.e. lib/cpuinfo)

I've submitted a bug report on the Second Life issue tracker (JIRA). If you find that you are indeed affected by the issue I described and that my temporary workaround resolves this issue for you, could you vote for the issue here: https://jira.secondlife.com/browse/VWR-5708 (you'll need to login with your full Second Life name and password). If you could also leave a short comment when you vote informing them that you were able to reproduce the error and that the temporary fix worked for you, that would be great.

edit: A representative from Vivox has already responded and has forwarded the details to the developers!

[HeXiLeD]

Jimeh: thanks a bunch ! It works for me too.
i will vote for the issue on SL.

ok... so .. while i have voice sound now; things are not 100% yet.

I can hear others but i cant use the microphone.
And while i can hear others for a bit; it will also crash the sound after a few seconds.
The time that it takes until the sound is gone, also depends on the card capture that i am using or if i play with the volume settings.

So far if i choose to use OSS it sems to be the one that is more stable.
I am with SecondLife_i686_1_19_1_1_RELEASECANDIDATE.

How about you guys ?

[HeXiLeD]

Currently testing: SecondLife_i686_1_19_1_2_RELEASECANDIDATE

This RC seems more stable since i get less log errors but i still have the voice crashing after some time.

Is the ebuild source or is it the binary package?

[HeXiLeD]

currently with games-simulation/secondlife-bin-1.22_rc7 instaled from portage and the issue still remains.
manual install also doesnt seem to solve the problem.

You can try my secondlife overlay at http://gentoo.techwolf.net/

I've been building from source for a while and adding openal and spacenav support. Had a few folks say to put them up and so I did.

Please reply if it works for you.

Best way to get voice support is to use a second sound card, or enable the motherboard sound if allready using a card, or use a bluetooth headset and point the voice to the second device.

[HeXiLeD]

Problem is now fixed with games-simulation/secondlife-bin-1.22_rc8 on EMT64

note: add games-simulation/secondlife-bin ~x86 to /etc/portage/package.keywords if you use 64bit

as for soundcards ....
