No duplex mode with the EHCI driver and USB hub. Is the problem solved?

Hi Pablo, Apparently, it works! I have the exact same USB port 'Intel Corporation 5 Series/3400 Series Chipset USB2 Enhanced Host Controller (rev 05)' and I never managed to run the UA-25Ex in full duplex until...today for the first time! (please note that I was using this patch as well https://gist.github.com/1168715 for another USB soundcard, but I believe now this is not what fixed the problem). Aurélien

A different direction in music - Whisper

by Julien Claassen

Hello everyone! Today I've made up and recorded a new piece. Just piano. It's no Bach and it's no prog rock. No fancy overboard processing either. The piece is called "whisper - Since In Love, Verity Is Altering". It's a piece about decisions and changing and importance of a human being. http://juliencoder.de/nama/whisper.ogg http://juliencoder.de/nama/whisper.mp3 Or go to the website: http://juliencoder.de/nama/music.html Equipment used: LinuxSampler and my Sampletekk black Grand piano library, the new Nama version for recording and finalising, fons' FIL plugin for some light EQing and jconvolver for the reverb. I do'nt know, which reverb that is. It was the one I last used for Shout. I'm not sure, if I made a note on that. It sounded good though. :-) I hope you enjoy it and as ever; Comments are welcome, the good and the bad.

by Aurelien

Hi! Just wanted to check whether someone used that device here, and could confirm me that it's using usual usb midi, and so is perfectly suitable for a use with ALSAseq? Thanks a lot. Aurélien -- Aurélien

ALSA +udev + Identify two identical audio devices

by Miguel Negrao

Hi all, I’m trying to configure a pc with puredyne 9.11 and 2 RME HDSPM soundcards[1]. I manage to get sound perfectly, and I also managed to merge the two sound cards into one using .asoundrc. My problem is that the cards are identical and at every boot they get a random order. I was trying to follow [2] to try to give them a name based on the hardware location of the pci cards. I created a file which I placed in /etc/udev/rules.d/85-wfs-script.rules with the following: SUBSYSTEM!="sound", GOTO="wfs_pci_cards" ACTION!="add", GOTO="wfs_pci_cards" DEVPATH=="/devices/pci0000:00/0000:00:14.4/0000:02:0e.0/sound/card?", ATTR{id}="HDSPM_1" DEVPATH=="/devices/pci0000:00/0000:00:14.4/0000:02:09.0/sound/card?", ATTR{id}="HDSPM_2" LABEL="wfs_pci_cards" Then when I reboot or reload the driver I get one of them with the correct name and the other one with “default” /proc/asound/cards 0 [default ]: HDSPM - HDSPM MADI RME HDSPM MADI at 0xfdce0000, irq 16 1 [HDSPM_1 ]: HDSPM - HDSPM MADI RME HDSPM MADI at 0xfdcd0000, irq 17 Which one gets the “default” name is random and changes every time I boot. I tried changing the number 85 to all sorts of numbers, to change the order in which the rule is run, but it doesn’t really make a difference. Running udevd --debug and reloading the driver reports : 1323357358.505334 [3088] udev_rules_apply_to_event: ATTR '/sys/devices/pci0000:00/0000:00:14.4/0000:02:09.0/sound/card0/id' writing 'HDSPM_2' /etc/udev/rules.d/90-wfs-pci-cards.rules:5 1323357358.505393 [3088] udev_rules_apply_to_event: error opening ATTR{/sys/devices/pci0000:00/0000:00:14.4/0000:02:09.0/sound/card0/id} for writing: No such file or directory Btw, the file is there, and doing "more /sys/devices/pci0000:00/0000:00:14.4/0000:02:09.0/sound/card0/id” yields “default” or “default_1”. How can I stop the “default” name overriding the names that I set in the .rules file ? Any help appreciated !!!! best regards, -- Miguel Negrão // ZLB http://www.friendlyvirus.org/artists/zlb/ [1] http://www.mjmwired.net/kernel/Documentation/sound/alsa/hdspm.txt [2] http://alsa.opensrc.org/Udev#Identify_two_identical_audio_devices -- Miguel Negrão // ZLB http://www.friendlyvirus.org/artists/zlb/

[bit OT]: help with booklet design

by Julien Claassen

Hello everyone! I'd like to design a simple CD-booklet. I'm not yet sure, if it will even be made public, the way I intend it to be, but perhaps it might. Since I can't do this on my own and can't afford a normal design-person to do it, I wondered if one of you might help. I could offer up to perhaps 30-40 EUR or some other favour in return (check website for accessibility, play keys for a track...). The basic design ideas are these, just so you know, the skills and perhaps tools required: Have a photo on the cover (rescaling?) and the title in fancy printing, perhaps hand drawn. Then inside just have a photo on one page and text on the next page. Something like this. the result should be a PDF - or other widely accepted format, that I can have printed in a copy shop or at a small printer's. Anyone willing to assist me in this endevour? Thanks in any case for reading up to this point.

Using your Nokia N9/N950 as a Dolby surround processor

ALSA: Using a plugin only for capture

by Julien Claassen

Hello everyone! For one of my users I wish to insert a few ladspa plugins for the microphone, but if at all possible not for the output, since then everything will get evilly distorted and fiendishly loud. I have the basic setup for the plugins, but I can't think of a way to only insert the plugins for inputs. All inputs of that card will do, since only the microphone will be in use. Unfortunately I can't raise the mic volume from the hardware any more and neither does the phone application have any additional volume control, that I can see. Does anyone have a good suggestion or two?
