No sound input on SB Audigy (FC4)

From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-GB; rv:1.7.10) Gecko/20050720 Fedora/1.0.6-1.1.fc4 Firefox/1.0.6 Description of problem: I cannot use the sound inputs on my SB Audigy card under FC4. Neither the line-in nor the mic socket works. Under both gnome-volume-control and kmix, there are no sound sources listed. alsamixer *does* report some capture channels, but setting line-in and mic to maximum doesn't produce any results. ALSA is using the snd_emu10k1 module to drive the hardware. The hardware name Alsa uses is "Audigy 1 or 2 [unknown]". I'm afraid I don't know how to get any actual hardware ID codes or anything -- if you need these please advise me! I should mention that the hardware worked perfectly under FC3, where is was just known as an "SB Audigy". There were far more options in gnome-volume-control then though... Version-Release number of selected component (if applicable): alsa-lib-1.0.9rf-2.FC4 How reproducible: Always Steps to Reproduce: 1. Install FC4 2. Witness sound recording not working on your Audigy card 3. Additional info:

I have a similar problem with a SoundBlaster Live! Value card and an on-board nVidia nForce2 AC97 card under FC4. VERSIONS -------- Linux version 2.6.12-1.1398_FC4 (bhcompile@tweety.build.redhat.com) (gcc version 4.0.0 20050519 (Red Hat 4.0.0-8)) #1 Fri Jul 15 00:52:32 EDT 2005 Sound Blaster driver: snd_emu10k1 nVidia driver: snd_intel8x0 alsa-lib-1.0.9rf-2.FC4 AMD XP 2500+ I originally tried to record sound through sox and then audacity. Nothing worked although both would sit there patiently until I stopped recording. On playback I always had an entirely empty track. Later I noticed that dmesg was warning that both programs were using the OSS emulation layer. I compiled a simple sound recording example which uses ALSA directly (see attachment) but that did not work for any device I passed to it either. It returned something like this: [patrick@localhost r]$ ./main /dev/dsp ALSA lib pcm.c:2090:(snd_pcm_open_noupdate) Unknown PCM /dev/dsp cannot open audio device /dev/dsp (No such file or directory) [patrick@localhost r]$ ls -l /dev/dsp crw------- 1 patrick root 14, 3 Jul 26 18:56 /dev/dsp It looks to me like the file exists, I am the owner and I can read/write on the device. I also tried turning of SELinux's enforcing mode but it made no difference. I tried the example on: /dev/dsp /dev/dsp1 and these files from /dev/snd/ crw------- 1 patrick root 116, 24 Jul 26 18:56 pcmC0D0c crw------- 1 patrick root 116, 16 Jul 26 18:56 pcmC0D0p crw------- 1 patrick root 116, 25 Jul 26 18:56 pcmC0D1c crw------- 1 patrick root 116, 26 Jul 26 18:56 pcmC0D2c crw------- 1 patrick root 116, 18 Jul 26 18:56 pcmC0D2p crw------- 1 patrick root 116, 19 Jul 26 18:56 pcmC0D3p crw------- 1 patrick root 116, 56 Jul 26 18:56 pcmC1D0c crw------- 1 patrick root 116, 48 Jul 26 18:56 pcmC1D0p crw------- 1 patrick root 116, 57 Jul 26 18:56 pcmC1D1c crw------- 1 patrick root 116, 50 Jul 26 18:56 pcmC1D2p The microphone is plugged in.

Some possibly related problems: - Someone compared changes in emu10k1 between ALSA 1.0.9rc1 and rc2 and rc2 breaks some things. http://sourceforge.net/mailarchive/forum.php?thread_id=6935674&forum_id=1752 Discussion on possible fixes on bottom of this Mandriva bug report: http://qa.mandriva.com/show_bug.cgi?id=15092 The most likely fix that may explain both my SoundBlaster Live! and AC97 problems seems to be this one: http://sourceforge.net/mailarchive/forum.php?thread_id=6944234&forum_id=1752 - A person having similar problems on SuSe 9.1 professional which may or may not be related: http://www.linuxquestions.org/questions/archive/47/2004/10/4/245204 - ALSA reported problem with Audigy 2: http://www.mail-archive.com/alsa-user@lists.sourceforge.net/msg13087.html
This bug also suggests that a VIA AC97 card requires "full duplex" set be set on the card for recording to work which may or may not be related: http://qa.mandriva.com/show_bug.cgi?id=15642

The same to me with SB Live! Value (emu10k1) In the [Capture] section of alsamixer it is *impossible* to turn up the volume of the Mic. Seems , thoughtt, at ATRPMS solved the problem, according to this: http://www.linuxquestions.org/questions/showthread.php?s=&threadid=339612 http://forums.fedoraforum.org/showthread.php?t=59515&page=2&pp=15 but I've not tried yet
Ok, so after some more experimentation I realized that I don't understand ALSA (ie. trying to use /dev/dsp instead of hw:0,0 terminology) and that my sample program I attached earlier is not necessary as I can test the ALSA stuff using aplay and arecord. Using these ALSA programs I've determined that my on-board nVidia nForce2 AC97 sound card DOES work for recording. The SoundBlaster Live! Value sound card still DOES NOT work for recording as it has before in FC1-FC3. Playback, however, is fine. In case this is a mixer problem instead of one of the possible problems I listed above here is a dump of my SoundBlaster mixer settings as provided by the command 'amixer scontents': Simple mixer control 'Master',0 Capabilities: pvolume pswitch pswitch-joined Playback channels: Front Left -

I am having the same problem with a VIA 8237 AC'97 setup (Elitegroup KT600-A motherboard, sound built-in).
It should be fixed in 1.0.10 alsa drivers, but these drivers don't go to FC4. You can check kernel from devel or recompile FC4 kernel with new drivers from upstream. In this case you can use alsa-lib and alsa-utils package from devel.
Why will this disturbing bug won't get fixed if there is a already existing solution for this?!?!? With kernel 2.6.13-1.1526 my sound is completley broken. No sound input or even output!
I've just installed SB Audigy in my favorite desktop PC (that runs FC3) and I have realised that no inputs are working! I've searched through groups and I've found many traces that inputs on this card USED TO WORK with FC3. So I downgraded the kernel to version 2.6.9 shipped primarily with FC3 and... inputs are working properly now! WHERE'S THE PROGRESS IN THIS WORLD? Also I must mention that I've done downgrade of xorg packages to version 6.8.1-12.FC3.21 and X runs faster now! I'm still having Radeon Value (7000), which isn't much liked by Xorg developers. Are Windows developers better then? Again, where the progress has gone?! There's still lots of work to do to make Linux a good system.
Add me to CC List since I'm not happy with having old kernel.
New kernel update for FC4 has the 1.0.10rc drivers so it can help you.
It wasn't easy, since I had to install lots of packages from FC4 over FC3 but it works fine now! List of these packages is following: alsa-lib-1.0.10-2.FC4.i386.rpm alsa-lib-devel-1.0.10-2.FC4.i386.rpm alsa-utils-1.0.10-1.FC4.i386.rpm checkpolicy-1.23.1-1.i386.rpm glib2-2.6.6-1.i386.rpm glib2-devel-2.6.6-1.i386.rpm hwdata-0.158.3-1.noarch.rpm initscripts-8.11.1-1.i386.rpm kernel-2.6.14-1.1644_FC4.i686.rpm libselinux-1.23.10-2.i386.rpm libselinux-devel-1.23.10-2.i386.rpm libsepol-1.5.10-1.1.i386.rpm libsepol-devel-1.5.10-1.1.i386.rpm mkinitrd-4.2.15-1.i386.rpm policycoreutils-1.27.2-1.2.i386.rpm system-config-soundcard-1.2.12-2.noarch.rpm SysVinit-2.85-39.i386.rpm udev-058-1.0.FC4.1.i386.rpm I've tried to install hal and dbus from FC4 but it needs libusb which needs glibc from FC4, so I can't use it on FC3. Also I must mention, that I had to configure arts and xmms to use OSS instead of ALSA. Fortunately, alsamixer works properly.
Created attachment 122366 [details] alsamixer - where's the switch for microphone?! Afrer some time (as I have installed Skype), I realised that there's still a problem with inputs. There's no microphone ON/OFF switch in alsamixer (nor in any other mixers). Strangely, there's ON/OFF switch for Mic Boost (see attached snapshot). What should be changed this time to make my Mike working?
You have to use "alsamixer -V capture" for access to the capture settings. It was splited into playback and capture interface....
Some how-to for the latest alsa-driver and FC4 is here: http://people.redhat.com/stransky/alsa/
Thanks for your advices Martin, -V capture option works fine, however there's no unmute switch for Mic there. Anyway, I was able to use Mic after I've set the volume to the max for it on the Capture.
If you use "alsamixer -V All" you should see all controls...
Created attachment 123213 [details] No Mute/Unmute switch for the Microphone line As you can see on the attached image, while using -V All there's no Mute/Unmute switch for Microphone line. However, for other input lines (Line1, CD, Aux) such a switch is available. Fortunately, changing volume for <Mic Capt> was enough to make my mike working on Skype.
Recording should be fixed in the latest drivers. Please reopen this bug if anyone here still has a problem with recording.
