No. My alsamixer on lenny shows no mute/unmute box, but it's a different
soundcard (Audigy2 soundblaster), and my alsamixer version shows as 1.0.16.
My alsa-utils package is 1.0.16-2, and that provides alsamixer, and other
stuff.
(By comparison, the Wikipedia screenshot
http://en.wikipedia.org/wiki/File:Alsamixer.png shows a mute/unmute box

That .png for alsamixer on the wiki is for a different soundcard than yours,
and all alsamixer controls are different, depending on your soundcard, so I'd
ignore that.
It doesn't help that I'm unfamiliar with your C media soundcard, so I'm a bit
in the dark. Are there any switches showing on your alsamixer? For example on
mine for the audigy2 soundblaster card there is a switch to change from
analogue to digital output. If this is set to digital, I get no sound, but
toggling it to analog brings the sounds up.
Perhaps you could post the output from running amixer on the CLI, just to see
what controls you have available.
Someone else who is also using a C media card on Lenny, may also have some
suggestions, that may resolve your problem.
Alternatively, there is the alsa-user mailing list, and someone there may
have
specific knowledge of known problems, and fixes for your card.
All the best.

Thanks Nigel, your clue about switches in alsamixer has done the trick.
I tried the following changes, testing each with speaker-test:
mute '3D Control' -- still no sound
change 'Line-In Mode' to 'Line In' -- still no sound
mute 'Exchange DAC' -- pink noise heard on earphones :-)
At this stage, CD playback was audible, but highly distorted. Curious
about 'Exchange DAC', I Googled and found
https://www.linuxquestions.org/questions/linux-hardware-18/c-media-cmi8738-chipset-no-sound-267807/
which also mentioned deselecting 'IEC958 Output'. So in alsamixer I
tried muting 'IEC958 Output', which removed the distortion. Brilliant!
For the record, here's my amixer output after fixing the problem:

No. My alsamixer on lenny shows no mute/unmute box, but it's a different
soundcard (Audigy2 soundblaster), and my alsamixer version shows as 1.0.16.
My alsa-utils package is 1.0.16-2, and that provides alsamixer, and other
stuff.
(By comparison, the Wikipedia screenshot
http://en.wikipedia.org/wiki/File:Alsamixer.png shows a mute/unmute box

That .png for alsamixer on the wiki is for a different soundcard than yours,
and all alsamixer controls are different, depending on your soundcard, so I'd
ignore that.
It doesn't help that I'm unfamiliar with your C media soundcard, so I'm a bit
in the dark. Are there any switches showing on your alsamixer? For example on
mine for the audigy2 soundblaster card there is a switch to change from
analogue to digital output. If this is set to digital, I get no sound, but
toggling it to analog brings the sounds up.
Perhaps you could post the output from running amixer on the CLI, just to see
what controls you have available.
Someone else who is also using a C media card on Lenny, may also have some
suggestions, that may resolve your problem.
Alternatively, there is the alsa-user mailing list, and someone there may have
specific knowledge of known problems, and fixes for your card.
All the best.

CMI8738 sound card - cannot hear sound in Lenny
Hi folks, I've installed a CMI8738 PCI sound card (C-Media 8738) on my dual-boot machine. When I boot Windows, I can hear sound, but when I boot GNU/Linux, I can't hear any sound. I have tried 3 different ways of generating sound: (1) Gnome Desktop|Preferences|Sound|enable System Sounds (2) Gnome CD Player (3) $ cat /usr/share/sounds/alsa/Front_Center.wav /dev/dsp bash: /dev/dsp: Device or resource busy The motherboard (Intel D865GBF) has an on-board sound system, which I disabled in the BIOS setup before installing the CMI8738 card. == $ uname -a Linux mercury 2.6.18-6-686 #1 SMP Fri Dec 12 16:48:28 UTC 2008 i686 GNU/Linux == $ groups robert dialout cdrom floppy audio video plugdev netdev powerdev == $ dmesg Linux version 2.6.18-6-686 (Debian 2.6.18.dfsg.1-23etch1) (da...@debian.org) (gcc version 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)) #1 SMP Fri Dec 12 16:48:28 UTC 2008 BIOS-provided physical RAM map: BIOS-e820: - 0009fc00 (usable) BIOS-e820: 0009fc00 - 000a (reserved) BIOS-e820: 000e6000 - 0010 (reserved) BIOS-e820: 0010 - 3ef3 (usable) BIOS-e820: 3ef3 - 3ef4 (ACPI data) BIOS-e820: 3ef4 - 3eff (ACPI NVS) BIOS-e820: 3eff - 3f00 (reserved) BIOS-e820: fecf - fecf1000 (reserved) BIOS-e820: fed2 - feda (reserved) 111MB HIGHMEM available. 896MB LOWMEM available. found SMP MP-table at 000ff780 On node 0 totalpages: 257840 DMA zone: 4096 pages, LIFO batch:0 Normal zone: 225280 pages, LIFO batch:31 HighMem zone: 28464 pages, LIFO batch:7 DMI 2.3 present.

Well the cards being detected according to /proc/asound/cards, and you're a member of the audio group. The card is supported with the alsa driver 1.0.16, which comes with Lenny, see below. Module snd-cmipci - Module for C-Media CMI8338/8738/8768/8770 PCI sound cards. mpu_port- port address of MIDI interface (8338 only): 0x300,0x310,0x320,0x330 = legacy port, 0 = disable (default) fm_port - port address of OPL-3 FM synthesizer (8x38 only): 0x388 = legacy port, 1 = integrated PCI port (default on 8738), 0 = disable soft_ac3- Software-conversion of raw SPDIF packets (model 033 only) (default = 1) joystick_port - Joystick port address (0 = disable, 1 = auto-detect) This module supports autoprobe and multiple cards. The power-management is supported. You may just need to open alsamixer in Gnomes terminal, and check the sound levels, or for any controls that may be muted. the M key toggles the mute/unmute. Running the command, speaker-test , without the quotes, should give you some pink noise output from your speakers (CTRL +C to quit speaker-test), if all the levels are ok, and nothing is muted that should be unmuted. The usual controls that need to be up are, Master, PCM, Front, CD. I don't use Gnome, but KDE, but it's worth right clicking on Gnomes volume control (top right), and see if anythings muted. I'm not sure if it's a right or left click, but there should also be a button for the mixer there as well. Sorry for the lack of info, but it's getting a bit late here in northern france, and I'm about to crash out. All the best.
