[linux-audio-user] novation remote 25 usb midi controller

by Eric Dantan Rzewnicki

I have not been successful in getting this keyboard recognized on the usb bus, let alone by the usb-audio driver. I'm going to see if I can get it working via straight midi into my ymfpci-based guillemot maxisound fortissimo. But, can anyone see anything else I can try? I've tried to gather as much info as I could think of...maybe I'm just not understanding something basic ... Please help. My system is debian testing (sarge) with kernel 2.4.19 with preempt and lowlatency patches and the following usb options turned on: CONFIG_USB=m CONFIG_USB_DEVICEFS=y CONFIG_USB_UHCI_ALT=m CONFIG_USB_AUDIO=m lsusb returns nothing and there is nothing in /proc/bus/usb/devices ( which I guess says the same thing. ) I compiled and installed alsa-0.9.6 drivers, libs, utils and envy24control. the drivers were configured like this: ./configure --with-cards=ice1712,usb-audio --with-sequencer=yes --with-oss=no I have the following in modules.conf: #sound specific modules alias char-major-116 snd alias snd-card-0 snd-ice1712 alias snd-card-1 snd-usb-audio lsmod looks like this: Module Size Used by Not tainted input 3296 0 (autoclean) snd-seq 35088 0 (autoclean) snd-usb-audio 36992 0 (unused) usbcore 55968 0 [snd-usb-audio] snd-ice1712 35656 0 snd-pcm 54528 0 [snd-usb-audio snd-ice1712] snd-page-alloc 5392 0 [snd-pcm] snd-timer 13284 0 [snd-seq snd-pcm] snd-ac97-codec 34008 0 [snd-ice1712] snd-mpu401-uart 3088 0 [snd-ice1712] snd-rawmidi 11616 0 [snd-usb-audio snd-mpu401-uart] snd-seq-device 3652 0 [snd-seq snd-rawmidi] snd-ice17xx-ak4xxx 1344 0 [snd-ice1712] snd-cs8427 5188 0 [snd-ice1712] snd-ak4xxx-adda 3372 0 [snd-ice1712 snd-ice17xx-ak4xxx] snd-i2c 2092 0 [snd-ice1712 snd-cs8427] snd 23812 0 [snd-seq snd-usb-audio snd-ice1712 snd-pcm snd-timer snd-ac97-codec snd-mpu401-uart snd-rawmidi snd-seq-device snd-cs8427 snd-ak4xxx-adda snd-i2c] aconnect -i: client 0: 'System' [type=kernel] 0 'Timer ' 1 'Announce ' acconnect -o: <nothing> lspci: 00:00.0 Host bridge: Intel Corp. 440BX/ZX/DX - 82443BX/ZX/DX Host bridge (rev 03) 00:01.0 PCI bridge: Intel Corp. 440BX/ZX/DX - 82443BX/ZX/DX AGP bridge (rev 03) 00:07.0 ISA bridge: Intel Corp. 82371AB/EB/MB PIIX4 ISA (rev 02) 00:07.1 IDE interface: Intel Corp. 82371AB/EB/MB PIIX4 IDE (rev 01) 00:07.2 USB Controller: Intel Corp. 82371AB/EB/MB PIIX4 USB (rev 01) 00:07.3 Bridge: Intel Corp. 82371AB/EB/MB PIIX4 ACPI (rev 02) 00:0a.0 Multimedia audio controller: Yamaha Corporation YMF-744B [DS-1S Audio Controller] (rev 02) 00:0b.0 Multimedia audio controller: IC Ensemble Inc ICE1712 [Envy24] (rev 02) 00:0d.0 Ethernet controller: Accton Technology Corporation SMC2-1211TX (rev 10) 01:00.0 VGA compatible controller: 3Dfx Interactive, Inc.

[linux-audio-user] laptop and knoppix

by Atte André Jensen

Hi I'm trying to figure out if all the hardware in my new laptop is supported. For this purpose I'm trying out knoppix for the first time, but sound is not working. sndconfig finds the card as "Intel Corporation|82440MX AC97 Audio Controller" but only a small click is heard when trying to play a sample. "play somesample.wav" returns "playing somesample.wav" and the aforementioned click is heard. Does anyone know knoppix well enough to help me, since I'd rather not install anything in case I have to give it back (if the hardware is not supported)? Thanks in advance... -- peace, love & harmony Atte

[linux-audio-user] esd alsa ens1372 input monitor problem

by WR

Hi all, I'm having a problem trying to use esd with alsa and an ens1371 card. setup on boxes A and B: alsa-driver-0.9.5_r2 alsa-lib-0.9.4 esound-0.2.29 linux-2.4.21-rc4-aa1 On box A, I'm using a cmipci driver, box B, an ens1371. modules.conf has identical (except for driver id) content on both boxen. Everything alsa works on both boxen, playback and capture. Esound playback works on both boxen. The Problem: Esound esdrec works on box A, but not box B. On box B, esdrec times out and exits (yes, esd is running). It appears as though it looks to a port for capture data, sees none, then bails. Esound documentation is famously anemic, googling got me this far... Weird bit to me is that non-esound alsa capture is working fine on box B, it's just that esdrec doesn't seem to be addressing the right port. Anyone have any ideas? Like how does esdrec know which port to see, or how do I tell it to look in the "right place" for a capture stream...or how to set the "default port" so esdrec "just finds it" like on box A... Many thanks!!

[linux-audio-user] asoundrc magic for multi outs

by Ross Vandegrift

Hello all, I have a session comeing up this weekend where I'll need three set of headphones monitoring the mix. This is a problem, since I have a Delta44, and am limited to four channels of output. I also have an SBLive I use for MIDI, and I'm trying to make a virtual device to take advantage of that output as well. I started with the asoundrc in the wiki for this in the wiki, at http://alsa.opensrc.org/index.php?page=TwoCardsAsOne but if I try to aplay to it: ross@turalyon:~$ aplay -D multi synth.wav Playing WAVE 'synth.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo aplay: set_params:783: Broken configuration for this PCM: no configurations available I pretty much snipped the config directly, and added lines for my additional channels. I also tried making a copy device, but this plays for a second (out of the Live) and then quits with an I/O error: ross@turalyon:~$ aplay -D copy synth.wav Playing WAVE 'synth.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo aplay: pcm_write:1025: write error: Input/output error Here's my ~/.asoundrc: pcm.multi { type multi; slaves.a.pcm "hw:0,0"; slaves.a.channels 4; slaves.b.pcm "hw:1,0"; slaves.b.channels 2; bindings.0.slave a; bindings.0.channel 0; bindings.1.slave a; bindings.1.channel 1; bindings.2.slave a; bindings.2.channel 2; bindings.3.slave a; bindings.3.channel 3; bindings.4.slave b; bindings.4.channel 0; bindings.5.slave b; bindings.5.channel 1; } ctl.multi { type hw; card 0; } pcm.ttable { type route; slave.pcm "multi"; ttable.0.0 1; ttable.1.1 1; ttable.2.2 1; ttable.3.3 1; ttable.4.4 1; ttable.5.5 1; } ctl.ttable { type hw; card 0; } pcm.copy { type copy; slave.pcm "hw:0,0" slave.pcm "hw:1,0" } Thanks for any tips! -- Ross Vandegrift ross(a)willow.seitz.com A Pope has a Water Cannon.

[linux-audio-user] TerminatorX Scratching Problem

by Rainer Poisel

Hi guys! In the last days had some nice experience with terminatorX. I think it works well, but I don't know if the scratching is working correct. I started scratching and noticed, that the soundfile is played only forwards whatever direction the mouse is moved. When I set the "mouse speed" to a negative value soundfiles are always played backwards when scratching (holding the left mousebutton or pressing the "space"-key). Is it possible to play the soundfile in two directions? For example: mouse moving upwards while scratching -> playing forward mouse moving downwards while scratching -> playing backward Like a real turntable :) Thanks for any suggestions! Friendly regards, Rainer (rainer.poisel(a)kstp.net)

Thanks a lot! I commented the "omit xfree86-dga" line and after that it worked fine. Friendly regards, Rainer

[linux-audio-user] Quattro Situation

by Austin

Okay Patrick... more headaches for you maybe? I finally bought a Quattro. All seems fine except I can't read/write to it. I assume it has something to do with this 'initialization' problem Takashi has mentioned, but I'm not sure. I'm really hoping to get this working soon so I can include it in the next Mandrake Audio HowTo blah blah. I used Patrick's .asoundrc, and the module loads fine. Everything that one expects shows up in /proc/asound. [root@gamma373-165 austin]# ls /proc/asound card0/ cards devices modules oss/ pcm Quattro@ seq/ timers version But I can't seem to use it: [root@gamma373-165 austin]# alsaplayer ALSA lib pcm_hw.c:1055:(snd_pcm_hw_open) open /dev/snd/pcmC0D0p failed: No such device snd_pcm_open: No such device (default) qinit seems to segfault: [root@gamma373-165 austin]# ./qinit Initialising quattro Segmentation fault (core dumped) Then nothing works: [root@gamma373-165 austin]# alsaplayer -d Quattro ALSA lib pcm.c:1908:(snd_pcm_open_noupdate) Unknown PCM Quattro snd_pcm_open: No such file or directory (Quattro) [root@gamma373-165 austin]# alsaplayer -d q4 ALSA lib pcm_hw.c:1055:(snd_pcm_hw_open) open /dev/snd/pcmC0D0p failed: No such device snd_pcm_open: No such device (q4) [root@gamma373-165 austin]# aplay -D Quattro apathetic.wav ALSA lib pcm.c:1908:(snd_pcm_open_noupdate) Unknown PCM Quattro aplay: main:484: audio open error: No such file or directory BTW, this is Mandrake Cooker (gcc 3.3.1, alsa 0.9.6, glibc 2.3.2, linux 2.4.21.6mdk).
