I am the submitter of that kernel bug. I am having Intel sound card and the problem only happened after upgrading to 3.9 kernel. That problem is in fact initialization failure for Conexant codec. Does your sound card use Conexant codec, too? You may get everything needed for troubleshooting by looking at [1] for alsa-info.sh scripts. Run it with --no-upload. If your sound works in 3.8 kernel, run it in both 3.8 and 3.9 kernel. That is useful if you really decide to submit a bug report or just wonder whether your problem is the same as mine. Hope to get your problem solved. Note: [1]: http://www.alsa-project.org/main/index.php/Help_To_Debug_Intel_HDA#Reportin…

Have found a bug in the Kernel (from another email here) that behaves in a similar way. Maybe having the same issue (https://bugzilla.kernel.org/show_bug.cgi?id=58351). Also, I think it is an Alsa issue. I disabled PulseAudio and the audio is still not working through Alsa.

[arch-general] Fully wroking GTK3(+GTK2) theme for Gnome 3.8?
by Magnus Therning 18 May '13

18 May '13

It seems it's a rather common problem that GTK3 themes partly break Gnome3.8 by preventing having a nice desktop background while letting the file manager draw the background: https://bbs.archlinux.org/viewtopic.php?id=162204 https://bbs.archlinux.org/viewtopic.php?id=161918 I've so far found only two (2!) GTK3 themes that work in this respect, the default theme Adwaita that ships with Gnome3.8 and Nokto3.8 (http://gnome-look.org/content/show.php?content=158033). I'm not particularly pleased with the aesthetics of either of them though. What's causing this behaviour in themes? (Hopefully it's easy to fix the broken themes I come across.) What other themes have you found that work properly? /M -- Magnus Therning OpenPGP: 0xAB4DFBA4 email: magnus(a)therning.org jabber: magnus(a)therning.org twitter: magthe http://therning.org/magnus

[arch-general] Problem with libimobiledevice, ifuse, and idevices
by Joaquin Villanova 17 May '13

17 May '13

Think something is broken in gvfs-afc, ifuse and friends while working with idevices. Nautilus shows me the devices in the right panel (the favorites one), both documentiation and the device itself and always show this error when trying to mont. <code>Message did not receive a reply (timeout by message bus)</code> I think I've done my homework on bbs, #archlinux and googling, and found the only way peopple resolved this problem was with ppas in *buntus so i want to look deeper... Also i got this from dmesg output when trying to mount manually with ifuse: <code> [ 105.595108] ifuse[500]: segfault at 2dd0 ip 00007ff49b7efc05 sp 00007ff4998e5cd8 error 4 in libimobiledevice.so.4.0.1[7ff49b7e3000+1a000] </code> But the interesting part is that <b> Shotwell can import photos from the device </b>. Surprisingly Rhytmbox cannot play music from it. In an iPad2 ( i'm going to suggest to Apple to change its name to <b> iCrap </b>) neither Shotwell or Rhythmbox can get photos/music from the device. I'm running iOS 6.3 (latest version). Also for more info here is my uname -a, also i think is important to mention that i'm using GNOME (latest version from main repos). <code> Linux arch 3.9.2-1-ARCH #1 SMP PREEMPT Sat May 11 20:31:08 CEST 2013 x86_64 GNU/Linux </code> I'm happy enough because i can retrieve at least the photos from the iPhone, but is annoying that this stopped to work.

[arch-general] about the removal of that systemd symlink...
by David Benfell 17 May '13

17 May '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I was alarmed, I think unnecessarily, when I saw the message that a symlink for systemd was removed on an upgrade. As near as I can tell, the boot sequence still relies on init, which links to the right place. Is there a better way to keep track of changes like this so I'm not surprised?

[arch-general] Sound broken, using pulse audio
by Carlos Alegria Galicia 17 May '13

17 May '13

Hi all, After the last kernel upgrade, my sound is not working after weaking up from hibernate. The device "PulseAudio" is shown in alsamixer, PulseAudio is up and running, the channels are shown in pavucontrol and even the level sound bar is showing the audio levels, but there is no sound. Everything works after shutting down - starting up again my system (not even using restart). I am using systemd to hibernate / restart my laptop. Thanks in advance, -- Carlos Alegría Galicia,

[arch-general] Broken sound with Linux 3.9.2 on Acer laptop
by BlissSam 17 May '13

17 May '13

After upgrading to 3.9.2 kernel, the sound did not work. However, the system CAN recognize my sound card, and my sound card appeared in `alsamixer` Downgrading the kernel can solve the problem. Providing more info: Acer Aspire laptop, with Intel i5 CPU, 2nd generation SandyBridge. `uname -a`: > Linux brilliant-laptop 3.9.2-1-ARCH #1 SMP PREEMPT Sat May 11 20:31:08 CEST 2013 x86_64 GNU/Linux `lspci | grep Audio`: > 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 04) `dmesg`: > Pasted here: http://p.vim-cn.com/cbbcw `cat .pulse/daemon.pa`: > default-sample-rate = 48000 > alternate-sample-rate = 44100 > default-sample-format = float32le `cat /etc/modprobe.d/alsa-base.conf`: > options snd-hda-intel model=acer (This file aims to fix another bug.

[arch-general] 'Check out-of-date packages' tool
by Anatol Pomozov 17 May '13

17 May '13

Hi everyone Per discussion in 'pacman-dev' maillist [1] I implemented a tool that tries to find Arch out-of-date packages. The tool scans PKGBUILD files is /var/abs directory, extracts download url and then tries to probe download urls for the next version. Next versions look like X.Y.Z+1 X.Y+1.0 X+1.0.0 If any of the new versions presents on the download server it reports to user as 'new version available'. Here is the tool sources https://github.com/anatol/pkgoutofdate To make its usage even more pleasant I added it to AUR https://aur.archlinux.org/packages/pkgoutofdate-git/ To use it please install pkgoutofdate-git package: $ yaourt -S pkgoutofdate-git Then update abs database and run tool itself: $ sudo abs && pkgoutofdate That's it. The result looks like ....... closure-linter: new version found - 2.3.8 => 2.3.9 perl-data-dump: new version found - 1.21 => 1.22 wgetpaste: new version found - 2.20 => 2.21 fillets-ng-data: new version found - 1.0.0 => 1.0.1 tablelist: new version found - 5.5 => 5.6 ...... There are some fals positive and negative results though, mostly because download servers return different sort of weird responses. I still work on work-arounds for all these cases. Hope you find this tool useful and it will help to make Arch software even more bleeding edge. [1] https://mailman.archlinux.org/pipermail/pacman-dev/2013-March/thread.html#1…

For example int SATD (int* diff, int use_hadamard) { int k, satd = 0, m[16], dd, d[16]; ... for (dd=d[k=0]; k<16; dd=d[++k]) satd += (dd < 0 ? -dd : dd); accesses d[16] before the loop is exited with the k<16 check. This causes the compiler to optimize away the exit test because the new value of k must be in the range [0, 15] according to ISO C. GCC starting with version 4.8 has a new option -fno-aggressive-loop-optimizations that may help here. If it does, then this is a clear sign that your code is not conforming to ISO C and it is not a GCC bug. I am surprised that I didn't hit the problem before but I am seriously considering using '-fno-aggressive-loop-optimizations' in my own makepkg.conf. I just want to test others feeling on this discovery to see if it wouldn't be a good idea to make the switch standard in Arch... ________________________________ CONFIDENTIALITY : This e-mail and any attachments are confidential and may be privileged.
