[LAU] kernel crashes with jackd (with Dell Precision M6600's integrated Intel HDA sound)

by Csillag Kristof

Hi, Lately, when experimenting with JACK, I began getting kernel crashes :( The platform is a Dell Precision M6600 mobile workstation, and currently I am using the built-in sound. (These are just experiments; I intend to use a different audio device for the final configuration.) I am using stock Debian kernel v3.1.5. The kernel log looks like this: ----------------------------------------------------------------------- [ 7555.763914] BUG: unable to handle kernel NULL pointer dereference at 0000000000000028 [ 7555.763952] IP: [<ffffffffa08ca7b8>] setup_bdle.isra.21+0x44/0xd9 [snd_hda_intel] [ 7555.763984] PGD 203005067 PUD 203004067 PMD 0 [ 7555.764005] Oops: 0000 [#1] SMP [ 7555.764021] CPU 3 [ 7555.764029] Modules linked in: snd_hda_codec_hdmi snd_hda_codec_idt snd_hda_intel snd_hda_codec snd_hwdep snd_pcm_oss snd_mixer_oss snd_pcm snd_seq_midi snd_rawmidi snd_seq_midi_event snd_seq snd_timer snd_seq_device snd soundcore snd_page_alloc xt_limit xt_tcpudp ipt_LOG ipt_MASQUERADE xt_DSCP ipt_REJECT nf_conntrack_irc nf_conntrack_ftp xt_state acpi_cpufreq cpufreq_stats mperf cpufreq_conservative cpufreq_userspace cpufreq_powersave ppdev lp rfcomm bnep bluetooth pci_stub vboxpci(O) vboxnetadp(O) vboxnetflt(O) vboxdrv(O) binfmt_misc uinput fuse nfsd nfs lockd fscache auth_rpcgss nfs_acl sunrpc iptable_nat nf_nat nf_conntrack_ipv4 nf_conntrack nf_defrag_ipv4 iptable_mangle iptable_filter ip_tables x_tables loop firewire_sbp2 uvcvideo videodev media v4l2_compat_ioctl32 arc4 brcmsmac(C) radeon ttm mac80211 drm_kms_helper dell_laptop drm brcmutil(C) i2c_algo_bit cfg80211 iTCO_wdt i2c_i801 dcdbas battery ac iTCO_vendor_support video processor button rfkill i2c_core pcspkr evdev psmouse serio_raw dell_wmi sparse_keymap power_supply parport_pc wmi parport ext4 mbcache jbd2 crc16 sha256_generic aesni_intel cryptd aes_x86_64 aes_generic cbc dm_crypt dm_mod raid1 md_mod sr_mod cdrom sd_mod crc_t10dif ehci_hcd xhci_hcd thermal thermal_sys ahci libahci libata firewire_ohci scsi_mod sdhci_pci sdhci mmc_core firewire_core crc_itu_t usbcore e1000e [last unloaded: scsi_wait_scan] [ 7555.764630] [ 7555.764637] Pid: 13399, comm: jackd Tainted: G C O 3.1.0-1-amd64 #1 Dell Inc.

> I have manually replaced these with the jack2 versions. IMO you should post the error messages. FWIW did you run ldconfig?

[LAU] fst, wine, Kontakt5 ... still no joy

Hi, (Sorry for the cross-posting.) After manually installing the 32-bit libjack packages on my 64-bit system, the original problem ("Can't connect to JACK") is gone; now I get a whole new set of errors instead :) When I try to start the Kontakt 5 VST from festige (via fst, via WINE), this is what I get: ============================ ----------------yo... lets see...

[LAU] newbie problems with FST

by Csillag Kristof

Dear linux-audio users, I am new here, and the world of pro-audio, too. I would like to run Kontakt on Linux. (Or, to be more specific, I would like to run Galaxy Pianos, which is powered by Kontakt.) My prime candidate for the job is FST. Here is what I have: - My system is a 64-bit Debian stable/testing/unstable hybrid installation. - I have a working Jack2 installation, and I can use native applications without problems. (Midi keyboard, fluidsynth, etc.) - I have compiled and installed wine 1.3.34. (I created a 32-bit installation.) - I have checked out, compiled and installed the GIT version of Festige (including FST) If I run festige, and configure a directory containing the Kontakt VST dll, festige finds them. When calling "info" on a plugin, I get this on the console: --------------------- Traceback (most recent call last): File "/mnt/user_data/home/pianist/local/share/festige/src/w_festige.py", line 84, in run output = getoutput(self.next_command) File "/usr/lib/python2.7/commands.py", line 50, in getoutput return getstatusoutput(cmd)[1] File "/usr/lib/python2.7/commands.py", line 60, in getstatusoutput text = pipe.read() IOError: [Errno 4] Interrupted system call --------------------- I checked and calling fstinfo.exe manually on the targeted DLL file gives meaningful result, but still, the info feature fails with the festige frontend. When I try to actually launch a plugin (with Jack already running), I get this: --------------------- unknown option character l jackdmp 1.9.8 Copyright 2001-2005 Paul Davis and others. Copyright 2004-2011 Grame. jackdmp comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details `default' server already active Failed to open server can't connect to JACK --------------------- I guess it is starting to jack manually. But why? It would be great if it would be configurable; for example, for me, jack is already running, and is doing other things. Anyway, if I stop jack, and let festige/fst start it, I get this: --------------------- yo... lets see...

(And what is the "unkown option character l" at the start?) * * * I am running jack2 (v1.9.7). Can you help me fixing this? Thank you for your help: Kristof Csillag

I tried several years with cheaper equipment, since for me RME already is evil regarding to the costs. Anyway, I hardly recommend to get a RME card if you are able to pay for it. I wasted too much time using other cards. Cheers! Ralf

[LAU] Kuş -- radio broadcast test talk

by Ali Polatel

Hello, I want to share a radio broadcast test talk among with some background music which is akin to binaural waves. You can find the recording here: http://sutros.com/songs/20057 I am not a musician and this was my first try with lmms and audacity. The talk is in Turkish which I originally sent to our google group: http://groups.google.com/group/kaotik/browse_thread/thread/7146376de624663a I will translate it to English. Beware: It is a chaotic free association! Bird ==== Good morning dear listeners! Be ready to say hello to the new day with our slightly loony radio! Today we are going to discuss birds. According to the statistics the case of turning into a bird is observed more commonly among higher educated, lonely or unemployed people. Another more interesting statistic tells us that people who were born in winter have a 10% more probability of turning into a bird compared to people born in the summer. If you still feel sleepy, listen to this! Experts say babies whose mothers had flu on the second phase of their pregnancy have a higher probability of borning as a bird. Friends, before I leave you alone with music, I would like to mention the symptoms of being a bird so you will be aware. Birds are extremely careless. They may make cyclic movements akin to tics. It is also note worthing that birds have decreased emotional senses and lack of eye contact. Last but not least, birds who destroy the barriers of their ego, *laugh* when they talk about birds they suspect or fear. Thank you for your patience! Coming from Erkin Koray in this sunny Mayugust morning! Şaşkın[1] [1]: http://fizy.com/#s/1aibkp -alip

[LAU] Listening to radio - is it possible?

by Josh Lawrence

Hey everyone - happy holidays to you all! With all of this radio talk going around, I wanted to ask a question that has been on my mind lately: Is it possible to listen to over-the-air radio (you know, the old kind) on your pc? If so, how does that work? I'm assuming there would be some hardware that would provide an antenna hook-up, but that's all I can think of. I'm a big AM radio junkie...I used to love trying to pick up far-away stations as a kid, so it would be a fun thing to put together. Thanks LAU! -- Josh Lawrence 903-490-3700

[LAU] Code drops: ivory and proaudio-sound-control

by Gabriel M. Beddingfield

Friends, In the course of the year I did a couple of applications that I'm pretty proud of. For some good reasons, I've withheld releasing them publicly until now: Ivory - a multi-touch, virtual MIDI keyboard controller This was originally intended as a proof of concept, but was so much darn fun that I pushed it to a beta-level application. I don't recall if it works with a mouse or not... but it's not nearly as cool with a mouse. http://gitorious.org/gabrbedd/ivory proaudio-sound-control - one-stop shopping for Jack and Alsa control This is a mash-up of QJackCtl and QasMixer. It discards the GIMP-like multi-window interface of QJackCtl (which is a major pain on a mobile device). It also adds direct access to hardware mixer controls by re-casting QasMixer as a widget inside QJackCtl. Say way you want about the visual style of QasMixer, but it's the most complete GUI interface to ALSA I've found. https://gitorious.org/gabrbedd/proaudio-sound-control CAVEAT EMPTOR: This code is released AS-IS, and I have no plans to maintain them. It's released in the hope that someone can benefit from them.[1] DEMO: There's a video here that demos these on the Indamixx 2 (at the MeeGo conference last spring) http://www.engadget.com/2011/05/25/meego-conference-2011-sights-and-sounds-… If you're in a hurry, fast-forward to about 1:13. It mostly demos Ivory... but you also get brief views of proaudio-sound-control while Tony is switching windows. -gabriel [1] For proaudio-sound-control... if someone decides to continue this concept, you'll want to have a chat with me first. It works, but is implemented in an unmaintainable way.
