Re: [LAU] Audio recording from Rosegarden+QSynth+Hydrogen

OT: Old Moog's Never Die

by Ken Restivo

... they just sit in the corner of someone's studio, collecting dust, until some random guy (me) gets called in to do some backup and archiving sysadmin tasks, and stumbles upon them: http://www.restivo.org/misc/mooggasm/ This one is Serial Number 1037/1038 (a FrankenMoog?), made by Mr. Moog himself, in April of 1971. Discrete transistors, NO OP AMPS, apparently impossible to keep in tune. No, it doesn't work, alas. The power amp section works (speakers go BOOM! when the thing is powered up, and noise can be heard when its output is turned up), but only OSC3 can be heard, faintly, as if it were bleed-through. No sound at all from OSC 1 or 2. I don't need yet another project, otherwise I'd offer to buy it, strictly for the cool factor... if it were ever working again it would be SO sweet. -ken

No playback anymore with M-Audio Transit and firmware madfuload

by Guillaume Pellerin

Hi all ! I use an M-Audio Transit at home which was working pretty good for some weeks. However, the playback hangs now... Although the device seems well detected and the firmware loaded, there is no sound playing back anymore. Some consequences of this new bug : - amarok gets the device and seems to play, but I get nothing on the output, - qjackctl detects the card, starts jackd but shows many XRUNs and always 0% as process loading. This bug can be reproduced on Debian Sid and Lenny. May it be due to some new methods used by udev to load the firmware or abnormal detecting by network-manager (see the logs) or a default config using 16 bit word length and not 24 bits ? Can someone reproduce this bevahior using the Transit ? Thanks for your help ! Guillaume Here are my logs : momo@wm16:~$ dmesg [10789.912122] usb 4-2: new full speed USB device using uhci_hcd and address 15 [10790.068078] usb 4-2: configuration #1 chosen from 1 choice [10790.075317] usb 4-2: New USB device found, idVendor=0763, idProduct=2806 [10790.075323] usb 4-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [10790.075326] usb 4-2: Product: Unknown [10790.075328] usb 4-2: Manufacturer: Unknown [10790.500038] usb 4-2: reset full speed USB device using uhci_hcd and address 15 [10790.637945] usb 4-2: device firmware changed [10790.637945] usb 4-2: USB disconnect, address 15 [10790.752036] usb 4-2: new full speed USB device using uhci_hcd and address 16 [10790.977030] usb 4-2: configuration #1 chosen from 1 choice [10791.047104] usb 4-2: New USB device found, idVendor=0763, idProduct=2006 [10791.047111] usb 4-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [10791.047114] usb 4-2: Product: Transit USB [10791.047116] usb 4-2: Manufacturer: M-Audio momo@wm16:~$ cat /proc/asound/cards 0 [ICH6 ]: ICH4 - Intel ICH6 Intel ICH6 with STAC9750,51 at irq 16 1 [pcsp ]: PC-Speaker - pcsp Internal PC-Speaker at port 0x61 2 [USB ]: USB-Audio - Transit USB M-Audio Transit USB at usb-0000:00:1d.3-2, full speed momo@wm16:~$ lsusb Bus 005 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 004 Device 016: ID 0763:2006 Midiman M-Audio Transit Bus 004 Device 002: ID 046d:c526 Logitech, Inc.

Thanks, but that didn't help, either. I even tried deleting asound.state and rebooting, but no luck. I ran alsaconf, let it find the Audiophile and modify modprobe.d. That put the Audiophile in as hw:0 and appears to have made it the ALSA default.

A second option is using your favorite text manipulation programming language to generate an ardour session file (ardour session files are human readable/editable XML, I recommend loading and arranging a few clips in ardour, saving the session, and using the resulting file as a template if you go that route).

snd-hrtimer ALSA module

by Dan Muresan

Has anybody successfully used the ALSA snd-hrtimer module, as present in ALSA 1.0.18a and 1.0.19? It seems to cause lock-ups in just a few seconds on a 2.6.27 kernel for me. The backstory to this is that I am trying to use Rosegarden on a 2.6.27 non-realtime kernel (a backport for Ubuntu Hardy from the kernel PPA). Rosegarden requires an ALSA timer (it cannot use /dev/rtc0 directly). The system timer-based snd-timer module works at 250 Hz (too coarse) and the traditional snd-rtctimer module is gone after 2.6.24. Therefore I tried to upgrade ALSA and use the new hrtimer module, which as reported doesn't work... As to the real-time 2.6.27 kernel, which I am sure everybody will advise me to use, it has some problems for me (including bad interactions with other drivers leading to lock-ups). Any thoughts? Thanks, Dan
