OSS 4.2 and Mumble

I decided to remove ALSA in replace of OSS. I'm satisfied with everything.... except for one thing. I cannot use my USB microphones in Mumble. After reading around the net, I noticed that the USB functionality in OSS isn't ready, but it seems to be loaded on my system. Mumble has OSS selected as default though, grayed out.
My question is: Is there anyway to get my USB microphone/USB webcam's mic working with Mumble?

Sweet! That did exactly what you described Splex. Now just to figure out how to get the mics actually working. For some reason, nothing comes through and ossxmix no longer shows both mics.

I have no idea what I may have done in the past ~ hours for them to disappear from the mixer.
EDIT:
Running the following command got 2 "USB sound device"s containing rec back on ossxmix, i'm assuming they're my USB mics. Still can't hear anything.

[Solved] OSS v4.1 and headphones question.

Hello
I want to buy headphones they will be from PHILLIPS or CREATIVE.
And here i want to ask i'm using OSS v4.1 and there's will be problems becouse i search on this forum about OSS and headphones and I find some problem with it.
Thanks a lot for answer

R00KIE wrote:Are they USB headphones? If not then I don't see why you should have any problems.
If they are USB then it can be a bit more tricky as USB support is experimental in OSSv4. I have a USB headset from Logitech that works just fine though.
To expand on this a bit, if your audio out port works without a hitch for either speakers or headphones, any problems you get are because of faulty headphones, and a replacement of the same model would work. Unless, like R00KIE said, they are USB. In which case, I can't even find a pair of headphones on linuxcompatible.org, so I have no idea how you'll be able to know beforehand. I guess if you have a laptop you could bring it to a store and try them out, if you have a store nearby that will let you.

Skype and Mumble problem

Hello,
When I open mumble skype goes to the "not responding state".
When mumble is still running and I start running skype , there is no window,
When I exit mumble and start skype the window is opening.
I'm sure I did not have this problem before just with the new version 7.05.85.102
Any idea how to fix this or to step back to an older version.
Thanks

I'm guessing you are on W7 x64, have you tried the x64 client?
http://wiki.mumble.info/wiki/Main_Page
Yes, I know it's a snapshot, not stable release, but it might resolve the resource conflict you are experiencing.
Teamspeak x64 works perfectly alongside Skype here, and should in theory cause the same resource conflict, but it's not.

HR replication oss note 550055 and 363187

Hi,
I have followed the oss note 550055. I believe that I have to use this note in SRM/EBP system. please confirm.
Next I have to follow the oss note 363187 for the initial load in the HR system.Please confirm.
Please note that I don't use the org. model when I apply the oss note 363187
What is the purpose of the org. model which I have created in the HR system and distributed to SRM/EBP system ?
When will I use this org. model ?
With regards,
Pranav

Hi Pranav,
I will talk about yr last question and not the first two
as we are in process to try this scenario.
The ORG structure replicated in EBP from R/3 HR is used for diff purposes viz.
To decide approvers for pur docs raised by employees of resp depts.
To derive various attributes of employees such as acc system, cost centres, catalogs which can be used, budgets etc.
To assign product catergories (matl groups) to purchasers.
PO value limits
Hope it helps.

OSS Note deimplemented and included in Support Package

Hi,
We have deimplemented note in version 2, because version 3 was not possible to be implemented in SNOTE.
Now it is deimplemented at all, and when I try to implement latest version of the note, I get the message
SAP Note already implemented by Support Package
How can I implement this note now? I checked the objects in the system and the note is not implemented.

Note number 1581093.
As mentioned in the symptom. Version 2 of the note is created to extend the functionality provided in the Version 1. Version 3 of the note is created to correct the error in Version 2.
Information from SPAM

Question about OSS Notes, Archiving and Support Packages

Hello,
does anyone know if all the OOS notes related to archiving programs corrections (category like "performances", "program error", "advance developments",
"legal functions", "corrections of legal functions", "problem", "exit added", "special developments"...) are all automatically appllied on SAP when a support packages is installed?
Thank you
Best regards

Looks like the only requirement is Vcenter and Vsphere 4 client. So version 4.0 and up is supported.
http://www.cisco.com/en/US/docs/app_ntwk_services/data_center_app_services/application_networking_manager/5.1/device_support/table/sdt.html
ANM 5.2 and 5.1 includes a plug-in that allows you to integrate ANM into a VMware virtual data center environment. VMware is a third-party product for creating and managing virtual data centers. Using VMware vSphere Client, you can access ANM functionality and manage the ACE real servers that provide load-balancing services for the virtual machines in your virtual data center.
To use the ANM 5.2/5.1 plug-in, you must use VMware vCenter Server and VMware vSphere Client 4.
For more information about using ANM in a VMware virtual data center environment, see the User Guide for the Cisco Application Networking Manager 5.2/5.1.

TAXINN is avialble from ECC 5.0 onwards. It is standard tax procedure by SAP. So no need to go for any OSS Note. TAXINN has to be copied from '000' client to our cleint.TAXINJ was in use upto 4.7 Verson

TUB 166 and OSS Note 1422655 -- Michigan FUTA

We have applied TUB 166 and would like to get the Michigan taxes straightened out since the changes are retroactive to 1/1/2009. I found OSS note 1422655 and it says 'Before apply the instructions of this note, it is necessary to configure unemploymnet tax type 11 for Michigan state in your tax model'. Does that mean that I need to add a record to table V_T5UTD (Config step 'Maintain Tax Types per Tax Authority') and that is the only thing I need to do? Thanks.

Hi ,
You have to mantain the following config. :
1) Tax Model Tables T5UTE, T5UTM and T5UTY.
2) Also mandatory to maintain V_T5UTD (Maintain Tax Type 11 per Tax Auth - - Michigan in this case) and V_T5UTI (Mantain Tax Type per Tax Company Code per Tax Auth ).
3) Also ensure that tax type 11 is maintained at BSI Tax Factory's end for Michigan
FYI: Tax Type 11 is Employer Debt Repayment Tax
Thanks And Regards,
Somdeb.

Problems with ALSA and OSS

Hi.
I'm a ArchLinux user and I have been having problems with my audio, specifficaly the microphone.
My microphone works well with Audacity and I use it for speaking trough TeamSpeaker and since TeamSpeak still uses OSS I installed alsa-oss and added aoss to my TeamSpeak command. But, for some reason, the application stopped working (this have nothing to do with my real problem) and as substitute I installed TeamSpeak in Windows XP running on Virtualbox with ALSA audio. Everything worked smoothly until some weeks ago.
The microphone on Virtualbox stopped working but I still hear sound. And the funny thing is that TS Linux got working again, but if I use it with aoss I cannot use the microphone but I hear sound and to have microphone I have to use it without aoss but then i dont have sound on other apps.
And to get microphone on Virtualbox I have to enable OSS in preferences and use aoss but then, wich I don't understand why, I dont get any sound with other apps. :\
I have no idea what triggered this problem.
My audio device:
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03)
ALC660-VD Analog

No one? :\
Not even why Virtualbox with OSS and aoss "steals" the sound to the other apps?

Mumble, alsa update and veromix probs

So I updated today to the newest kernel and it pulled down the newest alsalib too. I tried launching mumble but no kdeplasma has run away cpu usage.
I tried installing veromix-svn and mumble-git, but neither fixed this issue.
I'm fairly sure that mumble is to blame here; it never worked with pulseaudio selected as the input or output and I always had to leave it as alsa. Now I can only hear sound and the mic is broken along with the high CPU usage when I run the program.
Can anyone confirm that this is happening to them too?
Thanks,
DF

pacman -S base-devel && pacman -Suy should give you everything you need, except specific dependencies.
Ahh that what I get for posting without refreshing OP.

Activity Report download is saved without extension and unreadable

Hello,
The Portal Activity Report iView has a button which enables the user to download the report to his PC.
The problem is that when the user clicks on that button and saves the file it is being saved by this default name: com.sap.portal.activityreport.frontend.DownloadableActivityReport
The main problem is that it is being saved by default without any extension and after saving the user needs to manually add the .xls suffix.
Another problem is that once I open the report with Excel The Object Name column is unreadable.
Is there any way to resolve these issues?
Roy

Hi Roy,
> if it wasn't supported there
> or you would still consider it as a bug?
The feature in general of course was supported, but what I cannot say is if it was a known issue that it didn't work correctly. As I dont't use the ActivityReport, I also have no experience if it didn't work at some time and maybe now is working.
The wrong filename I don't expect to be corrected in the meanwhile, as said, that's a problem in some places. So at least for this you could open an OSS message. And maybe combine this with the problematic column issue.
But if upgrading to SP18 would be an option for you, maybe you could first test that.
Hope it helps

What is the difference between OSX 10.6 and 10.6 server? I need to install Snow Leopard in a Parallels VM and it only allows 10.6 server. Will Rosetta work if I use the server edition?

I MUST use an app that was discontinued which requires Rosetta, yet I also want to upgrade to Mavericks. I was told that Parallels and VMWare Fusion both support running Snow Leopard SERVER, but not Snow Leopard. Two questions: Will Rosetta run on Snow Leopard Server when it is running inside the Parallels/Fusion/whatever virtual machine which is running under Mavericks? The second question is: Is there any problem with running any specific software in Snow Leopard Server when it is set up this way?

Richard Cartledge wrote:
The problem with client as virtualised OS is the Apple EULA, not a technical one.
I don't know if it works, or you're just not meant to do it.
PS. If you download or have Snow Leopard DVD, you can install Rosetta in later OSs, certainly Lion and Mountain Lion and Mavericks.
insert your Snow Leopard disc, open the Optional Installs folder on that disc, and double-click the Optional Installs.mpkg package. The Installer will open and you’ll be prompted to click Continue a couple of times and then choose a destination for the installation. Choose your startup volume and click Continue yet again.
In the Custom Install on “nameofvolume” window that appears, enable the Rosetta option and click Continue. In the next window click Install to do just that.
NB/ I don't have any old software to test to see if it actually makes it work!
WRONG TWICE!
Bad idea to attempt to install Rosetta into Lion, Mt. Lion or Mavericks and good luck trying to remove it after that attempt. Result: NO powerpc app will run after that installation and you will have to complete a wipe of your hard drive and a complete pre-Rosetta install to get rid of Rosetta!
It was a common Urban Myth that the Snow Leopard EULA prohibited its virtualization in Lion or Mt. Lion on a Mac. That myth has been largely debunked over the last two years.
In addition, Apple's release of Snow Leopard Server at a 95% discount ($20) has rendered the issue largely moot!
OP: what application are we talking about here?
For example here is the long beloved powerpc application Appleworks running in Snow Leopard Server installed in Parallels for use in a post Lion world:

Using one iTunes library with Vista and XP on a single PC

Since I have converted my whole CD collection into AAC, my iTunes library
is quite large. I have now installed Vista on a second partition as dual-boot
with my old XP. I would like to access my iTunes library with both OSs - but can (and how) this be done ? I already changed the location in both Itunes to the same path, but the second iTunes running under Vista isnt able to import the songs.
Any hints?
Thanks in advance,
Andy

It's the "itunes library.itl" file in Windows, and the same thing without the itl file extension on Macs.
http://support.apple.com/kb/HT1660
You might be able to get it to update both copies in each partition with something like TuneRanger or SuperSync. That would run into some money, esp a Tune Ranger license for both Mac and Windows.
Why not put your ITL file on a USB stick or external hard drive, and run your itunes library from that? You can tell the Mac to use the .itl for iTunes by changing properties on it. That's what I did so I can sync my iPods from either my XP PC or Mac and not get that dratted message about "iPod synced to another library".
