Description of problem: I have a Toshiba L30 which has a ATI SB450 HDA Audio card according to the hardware detection (although doco suggests that it is a Realtek HD card). Fedora Core 6 detects the card but does not produce sound. The alsa mixer level is 100%. The only option I can think of is to try and install 1.0.13 if I can work out how to do that - I managed to update the lib but not the core driver. Version-Release number of selected component (if applicable): Alsa apparently is 1.0.12 in FC6. How reproducible: Always fails. Steps to Reproduce: 1. Requires the hardware I have and is the default detected card that will not work. Actual results: Expected results: Additional info: Attached is the log file from the fedora hardware detection.

Could you please check the latest drivers / packages? (ALSA 1.0.14rc1) How-to is here: http://people.redhat.com/stransky/alsa/
The same happens to me on a HP Pavilion Slimline s7620n PC. It detects this same ATI sound chipset: Vendor: ATI Model: Technologies Inc. SB450 HDA Audio Module: snd-hda-intel I will try and find out with HP what is the real sound chipset in the motherboard. My system has the original FC6 from the DVD installed (I cannot upgrade as it makes X11 freeze the machine). I may try upgrading the kernel only so I can get the alsa 1.0.14 as suggested (requires the newer kernel-xen to be installed, for the alsa-kmdl that is required by alsa-drivers 1.0.14). Some more details: I've noticed that I don't have a PCM Device when I bring up system-config-soundcard. In my previous system with FC5 there was one. I did not see any errors on boot with dmsg. Some file or directory seems to be missing: # aplay /usr/share/sounds/phone.wav aplay: main:550: audio open error: No such file or directory # aplay -D hw:0 /usr/share/sounds/phone.wav aplay: main:550: audio open error: No such file or directory
That is what the URL for this machine says: Onboard audio * Built-in Azalia 8 channel audio * Realtek ALC883 8-channel High Definition Audio CODEC Ref.: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00784400&lc=en&cc=us&dlc=en&product=3245534&lang=en It seems it is failing to detect this Realtek card and it is thinking it is an ATI card (BTW, the rest of the machine's chipsets seem to be from ATI).
OK, I solved my problem. I now have a PCM device (ALC883 Analog). Funny enough, the sound card is still detected as the ATI SB450 HDA Sound works though, so I don't care what sound chipset it is, ATI or Realtek (not sure if I can trust the HP docs or if Realtek just OEM something from ATI anyway). Both aply commands now work, the missing file has appeared with one of these packages I've upgraded/installed: # aplay -D hw:0 /usr/share/sounds/phone.wav Playing WAVE '/usr/share/sounds/phone.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo # aplay /usr/share/sounds/phone.wav Playing WAVE '/usr/share/sounds/phone.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo sound clear and loud. I installed: kernel-xen-2.6.19-1.2895.fc6 (the latest for FC6) alsa-driver-1.0.14-57_rc2.fc6.at alsa-kmdl-2.6.19-1.2895.fc6xen-1.0.14-57_rc2.fc6.at The last one, both from the alsa site. IMPORTANT: My system did NOT have the alsa-kmdl before, nor the FC6 repos have it. I had to install that as it was a dependency for the alsa-driver RPM from the alsa website listed above. I hope FC6 is updated, ot that at least these latest alsa drivers are included in FC7.
okay, looks fixed in the latest ALSA drivers.
