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
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.

Ahh! The planet comes through again.
Sorry about the wrong info then! I was wondering why I never had any
problems with my midisport. :)

hi,
i am searching for a software-solution like native instruments "Battery".
i have got a Yamaha DD-14 eDrum and want to trigger wave-samples with the midi-controls from the yamaha.

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.

OK so I mostly fixed the problems however i have to run vxloader manually.
Sorry for the noise.

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!

Hello,
I have a USB sound card device : U2A waveterminal 2 x 2 (Ego-sys) I try to use
it on my laptop. I didn't find anything on als-project. Do someone use this card
and have a modules.conf & .asoundrc done for this card?
thanks for your help

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!
