Hello, my onboard sound chip (CMedia 9739, on Epox 8RDA3+, with nforce2 chipset) doesn't support volume changing in hardware (CMedia's cmaudio driver for OSS does all the volume calculation in software). That means that I'm unable to change the volume with alsamixer or similar programs. Now my question: is it possible to tell Alsa to change the volume in software? Is there a plugin that does this? I've already tried the "Route & Volume" plugin, but it doesn't do anything. XMMS plays sound still at full volume, and mplayer says "alsa-control: error setting left channel, Invalid argument" when changing volume. My asound.conf entry for it looks like this: pcm.nforcevol { type route slave { pcm "hw:0,0" channels 2 } ttable.0.0 1; ttable.1.1 1; } Does anyone has an idea how to get volume control? Btw. I'm using the snd-intel8x0 driver for this chip. Thanks in advance, Oliver Gerlich

RE: [linux-audio-user] Cheap PCI MIDI interface

by Matthew Allen

Maybe it has something to do with my switch to linux being pretty recent(last 6 months)? I have used the Midisports under Windows for a while now, always keeping up to date with the latest drivers/firmware on the windows side. m. > -----Original Message----- > From: linux-audio-user-bounces(a)music.columbia.edu [mailto:linux-audio- > user-bounces(a)music.columbia.edu] On Behalf Of Fernando Pablo Lopez-Lezcano > Sent: Monday, April 05, 2004 11:48 AM > > > Ahh!

Ahh! The planet comes through again. Sorry about the wrong info then! I was wondering why I never had any problems with my midisport. :) m. > -----Original Message----- > From: linux-audio-user-bounces(a)music.columbia.edu [mailto:linux-audio- > user-bounces(a)music.columbia.edu] On Behalf Of Clemens Ladisch > The firmware files certainly are needed for the MidiSport devices ... > > > Fedora core, running the planet ccrma kernel. > > ... but I guess Planet CCRMA already comes with the loader and > firmware files. _________________________________________________ Scanned on 05 Apr 2004 16:31:28 Scanning by http://erado.com

RE: [linux-audio-user] Cheap PCI MIDI interface

by Matthew Allen

That said, I have never had to mess with firmware or anything weird with either my midisport 8x8 or 2x2. Don't ask me why, I just turn them on (8x8) or plug them in (2x2) after I boot and they come up just fine. Fedora core, running the planet ccrma kernel. m. > -----Original Message----- > From: linux-audio-user-bounces(a)music.columbia.edu [mailto:linux-audio- > user-bounces(a)music.columbia.edu] On Behalf Of Frank Barknecht > > BTW: I would stay clear from the M-Audio midi devices, not because > they wouldn't work (AFAIK they do) but you'll have to fiddle with > firmware loaders and such.

[linux-audio-user] VXPocket v2 help please

by Jonathan Beilin

I have a VXPocket v2 PCMCIA soundcard. I got pcmcia-cs working just fine and followed all the ALSA install instructions on the alsa-project. I started the pcmcia service and started alsasound. /proc/asound lists card0 (i8x0) and card1 (vxpocket). cat devices lists, for card 1, 32: [1- 0]: ctl 36: [1- 0]: hardware dependent . aplay -l lists no playback for this card, and alsamixer reports no mixer elems found for the card. xmms output plugin, predictably, also lacks an option to output to the card. any idea what's wrong? gentoo, running kernel 2.6.4-mm1 on a dell 8600. Any help is appreciated. here are the steps I took during installation: (for those unfamiliar with gentoo, the emerge command is used to compile & install packages) # emerge pcmcia-cs (copied some other guy's config.opts since cardmgr crashes w/ default options.) # emerge alsa-utils # emerge alsa-tools # emerge alsa-firmware copied vxpocket.conf from alsa source to /etc/pcmcia compiled a new kernel with ISA, PCMCIA, and ALSA support, with the VXPocket driver compiled in (not as modules). added these lines to /etc/modules.d/alsa: alias snd-card 0 snd-intel8x0 alias snd-card-1 snd-vxpocket post-install snd-vxpocket /usr/bin/vxloader options snd cards_limit=2 # modules-update restarted computer with the new kernel. #/etc/init.d/pcmcia start #/etc/init.d/alsasound restart (I also tried removing the i8x0 lines and making snd-vxpocket card 0 but that failed also. the intel i8x0 sound works just fine, it's just the vxpocket that is presenting a problem) Thanks again! _________________________________________________________________ Get rid of annoying pop-up ads with the new MSN Toolbar FREE! http://toolbar.msn.com/go/onm00200414ave/direct/01/

RE: [linux-audio-user] snd-hdsp+cardbus=distortion -- the sagacontinues (cardbus driver=culprit?) MORE UPDATE

by Ivica Ico Bukvic

Hi all, I've tinkered even further with the stuff and I do have my lspci and other logs (will post them shortly). I've tried now runnning card with the external Word Clock -- the results are the same (distortion persists). At this point what I know for a fact: 1) Soundcard is distorted no matter what app/framework (i.e. direct Alsa access vs. Jack) I use in Linux 2) Likely culprit is either PCMCIA cardbus driver or the audio driver itself 3) External Word clock does not fix the issue 4) Changing sample rate does not fix the issue 5) Apparently sound has gaps that are comparable in size to the sound data buffers (apparently 32 points) 6) I've updated BIOS and that did not fix it (yet the DSDT table is still trashed on my notebook but that should not affect the operability of the PCMCIA card -- see next point) 7) Tried using the card without ACPI and APIC and the IRQ was 11 together with the cardbus as well as with ACPI (patched 2.6.3 kernel) and APIC, having IRQ 17 for both the cardbus and the soundcard. Both sounded the same (distorted). Using only APIC without ACPI fails to allocate proper IRQ to cardbus (IRQ 0) resulting in failed modprobing of the soundcard. 8) In Win32, the card works fine on the same hardware and using the same IRQ 17 like in Linux, however, upon suspending/hibernating and resuming, the soundcard produces a similar but different kind of distortion than in Linux except when using 32000Hz sampling rate (???). 9) The color of the distortion changes in Linux when changing sampling rates of the card on-the-fly (Will post the link to the sound shortly). The sound plays slower and slower in Win32 when the distortion is present and higher sampling rates are being used 10) RME has officially ok-ed my cardbus ENE CB1410 for use in Win32 since they tested it in their labs and it worked ok (so all they talked about its problems before is not true any more) 11) The throughput is not the issue since I stressed the card in Win32 and it worked ok (16 outputs at 44100Hz sampling rate at 3ms latency is flawless using Directx and Cool Edit Pro/Adobe Audacity, as well as 8 outputs at 96000Hz at 6ms latency using ASIO in Max/MSP). 12) Even after resuming in Win32 DirectX and MME drivers still work ok, it's only that ASIO drivers crap-out. 13) At least one more person reported similar behavior as mine on RME-audio news server 14) At least one more person has the same problem in Linux like me 15) Once I resume from hibernate/standby in Win32, successive disconnects eventually result in weird stuff, even a BSOD. Here is the additional info regarding my notebook: Boot log using ACPI&APIC on 2.6.3 patched kernel that fixes IRQ misallocation and freezes when inserting PCMCIA card: http://meowing.ccm.uc.edu/~ico/eMachines/boot-with-acpi&apic.log Boot log without using ACPI&APIC on the same kernel: http://meowing.ccm.uc.edu/~ico/eMachines/boot-without-acpi&apic.log Detailed view of the "distorted" sound that reveals 32-points of sound followed by 32-points of silence: http://meowing.ccm.uc.edu/~ico/eMachines/Distortion.jpg Simple lspci output: http://meowing.ccm.uc.edu/~ico/eMachines/lspci-simple.log Complex lspci output (lspci -vvv) http://meowing.ccm.uc.edu/~ico/eMachines/lspi-complex.log Recorded sound with the aforementioned distortion (towards the end of it, namely last second I actually change the sampling rate on-the-fly using hdspconf)(WARNING: the sound is normalized at 50% but was recorded clipping, so there is some artifacts just from the clipping, but they are simply an addon on top of what is already wrong): http://meowing.ccm.uc.edu/~ico/eMachines/test.wav (1.7MB) TODO: 1) Log the Jack -R output (likely to be ridden with xrun's) 2) You tell me :-) Any help is greatly appreciated!
