[SOLVED] Is alsa still required if I start using PulseAudio?
I am a bit confused. PulseAudio claims to be a daemon, but does not has to be listed in DAEMONS array in /etc/rc.conf and is run as a normal user. Should I remove alsa from DAEMONS array or leave it there?
EDIT: after a test run, the empirical answer is: alsa has to stay in rc.conf
EDIT: after test run, removing alsa from rc.conf is possible. However, I have to restore volume settings manually the first time boots without alsa deamon.

If I understand the Wikipedia entry correctly, PulseAudio uses ALSA drivers. So, first, you completely setup ALSA as if you were using it by itself, then second, you setup PulseAudio to use ALSA.
By reading the Arch wiki, it appears that, yes, PulseAudio is a daemon, but no, there isn't an "/etc/rc.d" version to put in the DAEMONS array. Instead, you either start it by hand or the WM / DE you use starts it automatically.
Should I remove alsa from DAEMONS array or leave it there?
Wait, I have ALSA in my DAEMONS array? ...Oh, yeah, all that does is save and restore volume settings, right?

With the new OS do you still need the iprocessors to use multilple displays on AppleTV
I just downloaded the new OS and it seems they made some improvements with the multiple displays. Current I don't have the i processors so I cannot use the mirror feature with Apple TV, does this new OS still require those processors to use multiple displays with Apple TV? I have a Mac Book Pro that was purchase about a month before the new Macs were issues with the i processors.
None of the people I know have needed to use a bumper or other case with any of the iPhone 4s. The reports on the antenna problems have been rather overblown. Anyway, there's been nothing to indicate that the white iPhone 4 has any changes to the hardware other than a minor change to the proximity sensor and perhaps the camera flash.

Pulse Audio no longer detecting sound card; ALSA still detects
After a recent update, pulseaudio has stopped detecting my sound card. ALSA still detects my soundcard, and I was able to find the following in the verbose output of starting pulseaudio.
D: [pulseaudio] reserve-wrap.c: Successfully acquired reservation lock on device 'Audio0'

When I check out the ALSA directory mentioned, it turns out to indeed be the case that the entire ucm directory does not exist

I'm not at all familiar with pulseaudio configuration. Does anyone know of a good way for me to resolve this issue? Have I even identified the correct issue?
UPDATE:
I was able to work around my problem for the moment by symlinking the configuration file to the location that pulseaudio was actually looking for it
# mkdir -p /usr/share/alsa/ucm/HDA\ Intel
# ln -s /usr/share/alsa/cards/HDA-Intel.conf /usr/share/alsa/ucm/HDA\ Intel/HDA\ Intel.conf
Although this does get my sound back, it is a hacky work-around and obviously not ideal. Anyone who knows a bit about pulse configuration, I welcome your input here
Last edited by OakRaider4Life (2013-04-14 22:14:34)Thank you so much for posting your solution!
I was having the same problem. The funny part was it started happening (and not always) after KDE says that the Intel HDA device is "gone" and asking me to remove it from my configuration. Even by saying no it wouldn't work. Killing pulseaudio with
pulseaudio -k
would have everything fallback to Alsa but starting pulseaudio again wouldn't work.
Rebooting right away doesn't take care of the issue either but after a while the problem would go away...
Any inputs would be appreaciated! -
The music that was on this nano when I stopped using it a few years ago is still on it, and I want to replace it with other songs that I've added to my iTunes since then.
iPods (except for iPod touch) are not linked to any iTunes "account." They are associated with your iTunes library. The account in iTunes is your Apple ID, and that is used to buy and download content from the iTunes Store. It is not required to use an iPod.
The 1st (and 2nd) gen shuffle can only be used with one iTunes library at a time. When you connect it, iTunes should prompt you to start using it with your iTunes library, and warn that the shuffle's existing content will be erased. Have iTunes erase the shuffle, and it will be associated with your iTunes library going forward. You can then add content to your shuffle.
The need for the previous owner's Apple ID and password should only come up if you are trying to transfer existing content from the shuffle to your iTunes library, AND the previous owner had content purchased from the iTunes Store. Just cancel out of that step, if iTunes asks. -
I created one apple I'd when I started using the iPad. After some days, I had to create a new apple id
as there was some problem with the first one. Now at some places still my old apple Id is appearing. Pls adv how I change this to my new apple Id.Anything you downloaded with the first Apple Id will forever be tied to it, and will always require it to update.
The question here is, why did you think you needed to create a new Apple ID? What was the problem with the first one?
To get rid of th old one, you'll need to delete everything you downloaded with it, and then sign out of the ID in several places around the iPad.
Go to Settings->iTunes & App Stores->Apple ID->Sign out.
Repeat the process, for Facetime, Messages, Mail and any other App you need to sign out of. -

When I close Firefox, then later want to start up again, I get I message that Firefox is still running. With "START TASK MANAGER", I need to close Firefox in order to start again.
I have the same problem. Firefox won't unload regardless of how long I wait. Literally hours ... I must go in and 'end the process'. This has been a real hassle for a while now. Even considered giving up on firefox. Please look into this! An additional problem; I have to run firefox to get the updates, but I can't get the updates to take because I can't get firefox to unload so I can restart it.

Sales order is on overall block still requirements are passed to md04/md07.
Hello Experts.
Sales order is on overall block still requirements are passed to md04/md07.
Please suggest...Hi Experts,
Issue: Sales orders are on overall block at header level. still sales orders are passing demand in MD04 and MD07 -
here in this case the actual scenario is
This Sales order was created on 09/28/2007. with overall block at header level.
then sevral times header block for this order was removed & it was last set on 8 feb. 2009.
after this, there was no change in delivery block at header till the date.
in mean time at every month there was program from legacy system which used to change the below info from SO
(In schedule lines --> shipping tab).
except Delivery date.
Delivery date D 08/31/2007
Goods issue date 07/30/2009
Loading date 07/30/2009
Material avail.date 07/30/2009
Transportation Plan. Date 07/30/2009.
*if we replicate this scenario in dev. and check this, system will not allow to keep above dates as delivery date is in past.
Now if we check SO is on oveall block at header, but we can see Ruquirement for the same SOs in MD04.
(*Note : here we found that date in MD04 for requirement of this SO, is same as date on which legacy system changed the data in SO for schedule line.)
we have replicated the sales cycles like this in development with different possibilities of Blocks on SO header as well as Item level. but they are working fine with dev. and quality system, as all config. settings are fine.(as suggested above by experts).
but it seems like a bug kind of thing.
kindly revert if someone has faced issue like this ,knows to get rid of it.
Regards,

My audio stops outputting after a few songs in a playlist - itunes says its still playing, stopping and starting track recommences audio output. Mac book Pro Lion 16gb ram. Can be any song, any time, same song will play if I select it again. Bit of a bummer itunes is the main thing I use (macbook pro jukebox).
Most likely culprit is your Lacie drives which are notorious for flaky power supplies which cause just the sort of erratic behaviour that you describe. Have had similar issues myself. Lacie has been good about replacing my power converter-- twice. If you have seven of them, good luck finding the bad one or more. Like I said, the behaviour is erratic. Sometimes it'll work sometimes not. I can't comment on Samsung drives because I've never used them and have never heard anything about them. Same with Softraid. Why not just use Disk Utility. Sounds like you're ready for an external hardware raid. This will be much faster, much more reliable, and may even be cheaper than seven firewire drives. Check out G Tech, and Maxx Digital for starters.
Best of luck

My last computer crashed and my new computer doesn't have a disk drive. I downloaded the CS package, put in my serial number,but during install is is still requiring a disk. What do I do?
is your cs6 a upgrade?
if so, after entering your cs6 serial number you will be prompted to select the qualifying product from a dropdown. select the product you own and enter its serial number.
after entering each serial number at the correct time installation will proceed.
if no, what files (names and extensions) did you download and what are the file sizes shown on your hd? -
