Software :: Pulseaudio And More Than 1 Channel?
Mar 26, 2011
I've decided to give PulseAudio a try and since it is working almost without any problems; the only problem I haven't been able to solve (even after some searching through the Internet) is this one:At the moment I've got only 1 mixer channel for output, called Internal Audio Analog Stereo. Now this channel controls both the volume going to the integrated speakers of my notebook and to headphones as well. What I was trying to do is to separate those channels in the same way how ALSA does it without PulseAuio.ALSA Situation without PulseAudio:~ Master ~ Speaker ~ PCM ~ FrontALSA with PulseAudio: ~ Master (controls everything)I was hoping to use the Master and Speaker in PulseAudio. My attempts were unsuccessfulHere are some tech data about my distro, ALSA, PulseAudio and sound card:Linux Distro info + PulseAudio USE Flags:
Code:
Distro: Gentoo Linux

PC seems to run fine in single channel mode but monitor reports no input in dual channel mode and memtest86+ lists from 1-3 errors per pass in single channel mode. Motherboard (Gigabyte P43T-ES3G) can't be set for the 1.65 volts required by the RAM (2x2 of OCZ3P1333LV4GK PC3 10666). The mobo voltage choices are 1.6 or 1.7 volts. I have tried both and increased the MCH voltage from 1.1 v to 1.2 v, but so far can't get it to run in dual channel mode at all and single channel mode seems to run fine but I still get errors in memtest86+. Also tried optimized Bios settings and loosened memory timings (from 7-7-7-16 to 8-8-8-27 and tRFC 60 to 70) and reset Command Rate from 0 to 2. CPU is Core 2 Quad @ 2.4 Ghz, PSU is rated at 400 watts, Video card is Gigabyte GT220.

I'm trying to crack my wep password just for kicks, but I keep running into the same error. When I try to use airplay-ng for the packet injection, it always gives me the error " wlan0 is on channel -1, but the AP uses channel 6". I've tried setting wlan0 to channel 6 manually, but that doesn't help. I spent a while searching for a solution, but it seemed like each page had a different, usually highly complex solution, that still doesn't work. I have the most recent drivers for my wireless card, and it meets all the requirements. So, is there any solution to this that will actually work?

I've had nothing but trouble with Pulseaudio in Fedora 14. I had managed to get rid of it in Fedora 10 with the command: su -c "yum remove alsa-plugins-pulseaudio pulseaudio" I just don't want to have to deal with Pulseaudio anymore. It does not like my sound card and gets in the way. Is there a Linux distribution that does not use Pulseaudio ?

Thinking about building a new system, with 4GB of DDR3 RAM. I am just wondering, which would you prefer: Dual-channel DDR3 or Quad-channel DDR3? Does one have better speed performance over another? Will one way keep your system cooler?

I've installed openSuse 11.4 and since then kmix shows just one channel (ALSA Plugin. plugin container)
in openSuse 11.3 I could change one master channel a channels for my subwoofer and an other speaker.
How can I add the other two channels to kmix?

I have a 4.1 surround setup that the computer sees a 4 channel setup (stuff going to subwoofer is split out in hardware so all the computer sees is the front and rear l/r channels).
All well and good, but phonon isn't giving me an option to set my output to 4 channels, only stereo (which means my rear speakers are useless) or 5.1 (which makes me fear losing channels if I play anything with actual surround sound).

I have a creative sound card (ca106 driver) detected and working. This is a 5.1 capable soundcard and i also have 5.1 speaker system. The sound card works, however, the problem is that only the front speakers are working. I have checked vlc settings, in which front speakers, centre and rear are seen as different devices.

found one other post with this same issue, and the final reply was "I give up"...I got a fresh 9.1 install. I just want to record some audio, but it's only recording on one channel, the left channel.I tried audacity and sound recorder. checked the sound preferences, Hardware set to Analog Stereo Duplex. In audacity Preferences > Devices > Recording, 2 (Stereo) is selected.When recording in audacity the output meter for the left channel shows activity while the right channel looks like it goes up a little bit but doesn't peak like the left channel. I hear fuzziness in the right but all the sound is in the left

I have a fresh install of Ubuntu 10.04 and I cant seem get the sound working properly. I have a checked to make sure that nothing is muted, and I do have sound over the rear channel when I change the wiring on the physical machine. However, I get no sound over the headphone channel. I also changed the conf for pulseaudio to have a default of 2 sound channels. In addition the sound works fine in my Fedora 13 and Win 7 installs, this is a triple boot machine .

When I'm on Vista (I dual boot by the way) I see that my hard drive is about 13Gb smaller than it used to be, but I have no access to Ubuntu's files. However, when I am on Ubuntu I have access to a drive (is it a drive?) I believe is called OS and when mounted it lets me access all of Vista's documents.
Also I do not understand the difference between /home, OS, and System Files (It might be named something else, but the icon looks like a hard drive I believe).
I realize all this is pretty vague, but do you know a way to block this connection? I feel like Harry Potter looking into Voldemort's mind (lol).
PS Despite the Voldemort reference I am not a MS Windows hater.

I have a netbook with a onboard WIFI card(Broadcom 5727(rev 01)) and a Realtek RTL8191S USB WIFI donge. Both work.
My problem is; I can't get these to scan for AP's running on channel 12 and 13.
Is there a way to fix this?

I have a netbook running squeeze + lxde. Every time I boot, I have to open alsamixer and turn on my speaker channel. Master and PCM are both enabled and at 100%, as is everything relating to the mic. Speaker just refuses to work with me though.

Recently I have been trying out quassel, while its a good IRC client security-wise it does fail in one crucial aspect which is the GUI which needs a lot of polish. A
Anyways, this is my setup. I am usually on two networks irc.freenode.org and irc.oftc.net and have number of channels which I want to autojoin and also later be able to add channels to the list.
Let's say the chat list name is DebianIRC (which is the default chat list). Does anybody know how can I do both/either of the things. So things to be done are :-
a. As far as I understand quassel ONLY lets one chat list be from the first network. I haven't been able to figure out how to add the second networks channels to the list while doing the initial setup.
b. How to later add channels from either or even a new networks (quassel calls IRC domain servers such as irc.freenode.org/irc.oftc.net as networks) to an existing list . For an example if the list is named as DebianIRC.
c. Also does somebody know where the logs are kept and any tricks/tips people do with the logs. By default I want logging on and on some channels more intensive logging than others.

I have the issue that the right channel is nearly to be muted (very low gain, high distortions).

I'm using wifi "usb card" from airlive with zd1211 driver in Fedora 12 OS. And I cannot access channel 12 and 13. Perhaps for US restrictions. But in EU are allowed. Any idea how to enable them?
iw phy told me the card has 14 channels width but last 3 are disabled.
I tried "iw reg set EU" but "iw reg get" still return me "Country:98"
Also set env. variable COUNTRY=SK and execute crda returns me: Failed to set regulatory domain: -22
in dmesg I can see the regulatory domain is first set to EU but when zd1211 is loaded it is set to US

I had to replace the motherboard, processor, memory on a machine because the old motherboard died. It worked fine under the old board but the new board (Gigabyte 880GA-UD3H) is causing Fedora 11 (and the Fedora 14 Live CD) to fail when initializing an Adaptec AHA-3940UW SCSI adapter.
I was able to display the boot messages and found that the first channel on the adapter is fine, but the second channel causes the boot to hang. The messages are:
aic7xxx 0000:05:04.0: PCI INT A -> GSI 21 (level, low) -> IRQ 21
scsi6 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 7.0
<Adaptec 3940 Ultra SCSI adapter>
aic7880: Ultra Wide Channel A, SCSI Id=7, 16/254 SCBs
aic7xxx 0000:05:05.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22

openSuse v11.1linux 2.6.27.39-0.2-default x86_64realtek acl1200 codecSound for various devices is at best erratic. It is hit or miss whether sound emits at any given time.Sometimes Flash player (in Firefox) has sound, sometimes not.Sometimes mplayer has sound, sometimes not. (A workaround for mplayer is to install the ALSA dev package and rebuild mplayer. It still fails on the default channel but succeeds on ALSA.)The message in mplayer is

I was hoping that upgrading to 10.04 would fix my problems with sound and HDMI but alas it doesn't. I have an HP dv7 that I wish connect via an HDMI cable to my HDTV and play things like Hulu, Boxee, etc. with the sound coming out of my home theater system. I know that the hardware is capable of doing this because I have Windows 7 installed in a dual boot and it has no problems with pumping sound down the HDMI channel.
I've upgraded to Alsa 1.0.23 freshly compiled. With 1.0.23 I see HDMI settings in Pulse Audio Volume Control. However if I start say VLC and play a video, check pavucontrol and make sure the Playback is set to the HDMI channel. I can hook up the HDMI cable and I can see the video playing - but no audio. I've been in and out of all kinds of things like alsamixer, gnome-alsamixer, sound preferences, etc. and I've toggled things on and off in an attempt to get HDMI sound working but nothing works.
In alsamixer if I hit f6 I see my 0 card as HDA Intel and my 1 card as NDA NVidia. If I select NVidia I see only S/PDIF, S/PDIF 1, S/PDIF 2, S/PDIF 3. I can only mute or unmute these. I've tried both - nothing works. Let me know what sort of output/info you need and I'll post it. Here's some info I've seen others post:

i just installed ubuntu 10.04 on my computer, and tried to airodump, but noticed that its stuck on 11th channel, when i specified only channel 6 during scan, it gave me hosts from channel 6 and 11, but then i ran aireplay-ng and it runs on 11th channel as well, even when i put my card into monitor mode with a specific channel option. btw my chipset is AR9285 with ath9k driver. everything worked in backtrack. i also tried to reinstall aircrack which did not work.

I am on amd64, Lucid Lynx (10.04). Using the latest mplayer (MPlayer SVN-r31042-Ubuntu-RVM).
I'm trying to play a hi-def wmv. I get video and audio, but there is definitely some audio missing. The center channel is gone. I have music and sound effects, but the characters dialog is silent.

I'm relatively new to Ubuntu, and have just installed 10.04 on a toshiba portege M100 laptop. Having got over the intel video chipset problems I tried to connect to my WLAN. Network manager would not connect. I tried switching to WPA, WEP and no encryption. No effect I still could not connect. I also noticed that network manager can find other APs much more quickly than mine.Haveing done some searching I tried removing network manager and installed wicd. Was good at finding the AP but reported it as operatingon channel 0. Still would not connect. I tried changing the AP channel to 6, suddenly everyting worked. I switched back to network manager (wicd got in a tangle over hidden networks). Still works.
Having scoured the web for help I found reference to 10.04 kernel suporting US channels. and that I should create a file /etc/modprobe.d/cfg80211, containing "options cfg80211 ieee80211_regdom=EU". I have tried this and it doesnt have any effect. I have noted that there are numerous variants of this advised by different people.Whilst at home I can operate my AP n a US channel, when I am on the move I cannot. I would like to get this working if at all possible.For info the wireless adaptor reported is:
*-network:1

product: PRO/Wireless 2200BG [Calexico2] Network Connection

I just created a new username and registered it. Then created/joined a channel, and it said I was the op. Then I exited my IRC client and logged back on, went to my channel, and it gives me the message Code: Now talking on #mychannel
* gibson.freenode.net sets mode +n #mychannel
* gibson.freenode.net sets mode +s #mychannel
* services. removes channel operator status from GrantStone
* *** Notice -- TS for #mychannel changed from 1288755739 to 1288751750
* services. sets mode +c #mychannel
* services. sets mode +t #mychannel
* services. sets mode -s #mychannel
* ChanServ (ChanServ@services.) has joined #mychannel
* services. gives channel operator status to ChanServ
* ChanServ (ChanServ@services.) has left #mychannel
How do I fix this? How do I re-become the OP for my channel? Do I need to use the AOP command?
