[linux-audio-user] emu10k1 no 64:0 input port

by Stefan Ulbrich

hi, i want to connect my keyboard to my pc (sb Live!) in oder to use it as a softwaresynthy. i've read aconnect 64:0 65:0 should do this ... but: stef: ~ $ aconnect -lio client 0: 'System' [type=kernel] 0 'Timer ' 1 'Announce ' Connecting To: 63:0 client 65: 'Emu10k1 WaveTable' [type=kernel] 0 'Emu10k1 Port 0 ' 1 'Emu10k1 Port 1 ' 2 'Emu10k1 Port 2 ' 3 'Emu10k1 Port 3 ' i can't find this port 64:0. here is my the alsa passage of my modules.conf: # ALSA portion alias char-major-116 snd alias snd-card-0 snd-emu10k1 # module options should go here # OSS/Free portion alias char-major-14 soundcore alias sound-slot-0 snd-card-0 # card #1 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss #my own settings alias midi snd-synth-emu10k1 alias snd-synth-midi snd-seq-emu10k1 alias snd-seq-midi snd-seq-emu10k1 (i tried it also without the "alias midi snd-synth-emu10k1" line) i compiled alsa with ./configure --with-cards=emu10k1 --with-sequencer=yes;make; make install i use debian sid. what am i doing wrong? with muse i can use the /dev/snd/midiC0D0 for recording thank you stefan

I thought that I remembered that the Midiman Audiophile 2496 had been working with spdif for a while for me at least, though I have the dat on the Delta 1010 in the music room now. I know that there was a lot of ups and downs with the drivers and spdif at first. I did have to cook up my own .asoundrc for it, but that's kind of expected with a mutichannel chip being used on a simple card. Tracey

[linux-audio-user] Straight-talking digitally

by Paul

Hi all, This might seem like a silly question, but I'm having an unexpectedly hard time putting together something I consider to be quite simple in essence. The intent: play music from PC (eg .ogg/.mp3 etc) via S/PDIF to an external DAC, and thence to sound system. The problem: finding a soundcard supported by Linux and which offers the option of unadulterated digital output. Ie. I want the soundcard to simply stream the bits at 44.1Khz (or 48) and not shag around with it in any way. My current setup is a compromise. I have onboard sound with a VIA8233 (Avance AC'97) 6ch chipset, and am using Windows XP with this, since the latest ALSA driver doesn't produce any sound on the S/PDIF output (although the optical port lights up). Trouble is, I don't trust the Windows driver, since the control panel for it allows me to select DSP environments and use a graphic equaliser. With the environment set to "none" and the equaliser off is it providing a "pure" bitstream un-molested in any way? Who knows. So, the question to you is simply: do you know of any soundcards which would fit the bill - ie. with a fully working Linux driver, and known to be configured to produce "pure" digital out. Cheers, Paul. -- Lubarsky's Law of Cybernetic Entomology: There's always one more bug.

[linux-audio-user] ISO images from Audio CD's?

by Dave Price

Good morning, I read (somewhere) that it is possible to make a directly useable Hard Disk 'Image File' from an Audio-CD. I am familiar with mkisofs for sets of data files and mounting the iso-9660 images as loop(ed) devices to access the files within the resulting image file. Also, I know that cdrdao builds a .bin temp file when you make a copy ... Are these files interchangeable? How would one mount an Audio 'image file' to play it, since you usually do not mount Audio CD's - players like xmms just use the raw device (right?) Any hints or pointers (urls) would be appreciated. aloha, dave

[linux-audio-user] [ANN] ams-1.5.5 fixes serious bug

by Dr. Matthias Nagorni

Hi, ams-1.5.5 is available from http://www.suse.de/~mana/kalsatools.html. It fixes a serious bug in synth.cpp which causes the machine to freeze when ams is started as root. Some example patches for the bode frequencer LADSPA plugin included in the new 0.3.3 version of Steve's plugin set have been added as well. Have fun !

[linux-audio-user] mp3 live-encoding with sox and lame

by Christoph Rupp

Hello list! (I have searched for an answer to this question in google and some other lists but didn't find something helpful... sorry if this has been asked before) i want to have realtime-encoding of my soundcard line-in with sox and lame (or something similar - i need command line tools). Now i use rec -t wav -r 44100 - | lame -m m -a -b 64 - (i need 44.1 khz/64 kbit). But all 5 or 7 hours sox crashes; there's an older thread on the sox mailing list: http://sourceforge.net/mailarchive/forum.php?thread_id=1083489&forum_id=3958 which says that this is due to a counter in the wav header which overflows and that you should use .raw instead of .wav. But whatever i use doesn't sound right: sox -t ossdsp -w -s /dev/dsp -t raw -r 44100 -c 2 - | lame -r -m j -b 64 -x -s 44.1 --resample 44.1 - It sounds dump: http://www.kochenmachtspass.de/test3-ms.mp3 I have tried many other options like -c 1 (leads to noise) but i cannot find a solution... Maybe someone of you knows a solution? Thanks Chris ===== http://www.crupp.de __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.

We will recheck. I have immense faith in Fernando, but everyone makes mistakes.

[linux-audio-user] SMP motherboards?

by Taybin Rutkin

Does anyone have any recommendations for cheap SMP motherboards? Something that can handle a couple 667 PIIIs would be ideal, but if the total price including CPUs is <$300, I'll consider it. My motherboard seems to not work with SMP anymore (freezing, restarting). I'm pretty sure it isn't a kernel thing because I've tried every version between 2.4.17 and 2.4.20 and they all act the same. It used to be rock solid at 2.4.18. Alternatively, I'd like the name of a good vendor of motherboards. Taybin -- http://www.piratesvsninjas.com

by Mark Knecht

Thanks Paul. I'm still struggling with getting this new card going. Fernanado and I are working through the issues one at a time by doing a Planet RPM for the newest version alsa and have applied the one line patch that you pointed me at the other day. However, I'm still not running. 1) Fernando applied the one line patch applied: --- hdsp.c-orig 2002-12-03 19:28:40.000000000 +0000 +++ hdsp.c 2002-12-03 19:28:06.000000000 +0000 @@ -2966,6 +2966,7 @@ switch (rev & 0xff) { case 0xa: + case 0x64: /* hdsp_initialize_firmware() will reset this */ hdsp->card_name = "RME Hammerfall DSP"; break; 2) Alsaconf works, sort of. modules.conf gets built, but my machine will not reboot after running it. Don't know why. 3) When I boot I see the following message in /var/log/messages Dec 9 12:39:40 Godzilla kernel: Hammerfall memory allocator: buffers allocated for 1 cards Dec 9 12:39:40 Godzilla kernel: RME Hammerfall-DSP: no cards found Dec 9 12:39:40 Godzilla insmod: /lib/modules/2.4.19-1.ll/kernel/drivers/sound/pci/rme9652/snd-hdsp.o: init_module: No such device 4) lspci -v shows the card is there: 00:0f.0 Multimedia audio controller: Xilinx, Inc.: Unknown device 3fc5 (rev 64) Flags: bus master, medium devsel, latency 32, IRQ 10 Memory at f6000000 (32-bit, non-prefetchable) [size=64K] I'm completely puzzled.

[linux-audio-user] PCI_DEVICE_ID_XILINX_HAMMERFALL_DSP

by Mark Knecht

Hi, Where are the definitions for PCI_DEVICE_ID_XILINX_HAMMERFALL_DSP and PCI_VENDOR_ID_XILINX kept in the alsa code? Thanks, Mark static struct pci_device_id snd_hdsp_ids[] __devinitdata = { { .vendor = PCI_VENDOR_ID_XILINX, .device = PCI_DEVICE_ID_XILINX_HAMMERFALL_DSP, .subvendor = PCI_ANY_ID, .subdevice = PCI_ANY_ID, }, /* RME Hammerfall-DSP */ { 0, }, };
