PulseAudio in realtime or high-priority mode

by Jonathan E. Brickman

Anyone using Pulse in realtime or high-priority modes? Experiences, anyone? I have a nice stable system in which Pulse sends all to Jack which then sends to ALSA, and am wondering if I should perhaps just use Pulse to take external inputs. Or is there a straightforward way to get one Jackd patchbay to handle input from two or three different whole audio devices? J.E.B.

Another direction

by Folderol

Having re-discovered the guitar, I've been getting some practice in. I don't know what the style I like is called, but it consists of picking a sort of melody from the lower strings with the thumb, then using fingers over the other strings to play arpeggios. After much practice, I was able to get through a 4-5 minute 'song' without a break or significant mistake. Once I had that sorted I moved over to the synth and produced some backing and a couple of 'verses' of lead. When I put that up on one of the music collaboration websites, a friend very quickly came back with complementary guitar line, along with a very nice guitar lead for the middle verse, after which I was then able to work out and add a subdued (synth) bass line. And there it stayed for a while. I couldn't think of where to take it. I just knew it wasn't 'complete'. It also didn't have a title, and finding that turned out to be the catalyst, because as soon as he heard it my friend came back with lyrics, half sung half spoken. All that was needed was a bit of tidying up and here is our complete collaboration. I hope you like it. http://www.musically.me.uk/music/Gone_Fishin.ogg -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

Dear all, I've just published the second Monthly Round-Up covering the month of August: http://linuxaudio.org/node/115 Thanks to Robin for giving me access to the linuxaudio.org site so I can now publish the Round-Ups directly on linuxaudio.org. And thanks to the people at LinuxMAO (linuxmao.org) for providing so much valuable information. Best, Jeremy

anyone good at musescore?

by alexander

Is there a way to change where accents are being placed by default? Dunno if it's a bug but as it is now they pop into existence right in the middle of the notelines and it's really annoying having to move them(making drum exercises) specially since they often sit below other notes making it more or less impossible to effectively select them. Thanks in advance!

ubuntu maverick + jack

by maex＠firstfloor.org

hello i recently switched my os from debian squeeze to ubuntu maverick. ok. since years i am useing the nice edirol ua-25 sound device without any problems so far. but, ubuntu changed this. its seems jack on maverick isnt able to handle a second sounddevice. at least the ua-25 isnt supportet at all and the jackd response with an error message: -jack was stopped with exit status 255 -post shutwodn error 256 -could not connect to jack sserver as client - overall operation failed. trying to get pd running with alsa for instance, results in some io stuck, no sound s playing. the fundamental integration of the pulseaudio server seems to work well for the very basic of buildin soundsupport, but at least for me its an unbreakable barrier for a further useage of this distro. has anyone a idea how to be able to run jack with a second and external hardware? or simply change the distribution,... to osx ;-). m

Terrasoniq Phase X64 USB audio interface?

by Hannes Rohde

Hi all, I just received my new toy, a Terrasoniq Phase X64 USB sound interface.

Re: [LAU] [alsa-devel] Terratec EWS88D (ice1712) optical stuck on ADAT (no IEC958 optical i/o)

The controls of interest, 'IEC958 Input Optical' 'IEC958 Input Optical' 'ADAT External Master Clock' 'ADAT Output Optical' 'ADAT Through' 'Enable ADAT' -- all appear in alsamixer(1) and they're all "stuck" at the current settings. Using either 'm' or 'space' or any other means that would normally change a boolean value for other ALSA properties do nothing for the above values in alsamixer(1). Basically, it appears that the property toggles, and then flips right back to the previous state (because that's what ALSA says it's at). Similarly, when set from the commandline, the ALSA result indicates the value stays the same: amixer cset iface=MIXER,name='IEC958 Input Optical' true numid=95,iface=MIXER,name='IEC958 Input Optical' ; type=BOOLEAN,access=rw------,values=1 : values=off > I am fairly sure that the ice1712 driver has no run-time mechanism for > enabling/disabling the paired digital streams that are ADAT on EWS88D, and > go > to/from the AK4524 codecs on most other versions. Seems like there's something of it in the code, and certainly the Windows drivers and the hardware itself support this functionality.

Terratec EWS88D (ice1712) optical stuck on ADAT (no IEC958 optical i/o)

by Niels Mayer

I just scored a nice Terratec EWS88D for $20.00. :-) ( http://nielsmayer.com/envy24control/EWS88D_Board_L.jpg missing midi cable though (*)) It works nicely with Linux and http://mudita24.googlecode.com , although it's missing some important controls to turn off the ADAT parts of the card. Alas, it wouldn't help to support them in mudita24, as I cannot get them to change values through standard ALSA tools like amixer(1) and alsamixer(1). Therefore, the question: is what is it about snd-ice1712 that prevents the mixer control values detailed below from changing, and is there anything I can do to fix it? (sometimes you want to use this card in it's dual IEC958 optical + spdif I/O config, other times, you want to use the optical for ADAT and the spdif for IEC958, which is the only configuration I can get currently.) The results from amixer(1): http://nielsmayer.com/envy24control/terratec-ews88d-amixer.txt Results of "cat /proc/asound/EWS88D/ice1712": http://nielsmayer.com/envy24control/terratec-ews88d-ice1712.txt My attempts at changing optical port from ADAT to IEC958.

The target machine for this card will actually be running Fedora13, however, that machine hasn't been decommissioned, wiped, or setup for that purpose yet....
