From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; rv:1.7.3) Gecko/20041020 Firefox/0.10.1 Description of problem: I have been installing and re-installing Fedora Core 3 onto my Fujitsu-Siemens A1640 notebook (AMD Athlon64 3400+, 1Gb of RAM & 80 Gb hardisk) for most of the weekend; I have been alternating between the FC3 install DVDs for x86 and x86_64. My observation about redhat-sound-config is as follows: 1. During installation (and subsequently), redhat-sound-config for x86_64 FC3 reports my soundcard as Vendor=Silicon, Model=Integrated Systems [SiS] Sound Controller, Module=snd-intel8x0, and clicking the "Play test sound" gives a perfect three-chord performance. 2. During installation (and subsequently), redhat-sound-config for x86 reports Vendor, Model and Module as above, but clicking the "Play test sound" *does not produce any sound*! I do not get any sound from Gnome apps either. So, why is x86 FC3 silent on my machine, but x86_64 FC3 is okay? I tried comparing the /etc/modprobe.config files but they look the same to me. I tried running alsamixer and looking at the settings- they appear the same for each install; alsamixer reports card=SiS SI7012, chip=Realtek ALC655 rev 0, Item=External Amplifier. So, I checked /etc/alsa/cards/SI7018.conf, /etc/alsa/cards/SI7018/sndoc-mixer.alisp and /etc/alsa/cards/SI7018/sndop-mixer.alisp; these files appear to be identical for both x86 and x86_64 installs. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Install FC3 x86_64 DVD edition onto Fujitsu-Siemens Amilo A1640 notebook computer. 2. Check configuration of soundcard. 3. Install FC3 x86 DVD edition onto Fujitsu-Siemens Amilo A1640 notebook computer. 4. Check configuration of soundcard. Actual Results: 1. During installation (and subsequently), redhat-sound-config for x86_64 FC3 reports my soundcard as Vendor=Silicon, Model=Integrated Systems [SiS] Sound Controller, Module=snd-intel8x0, and clicking the "Play test sound" gives a perfect three-chord performance. 2. During installation (and subsequently), redhat-sound-config for x86 reports Vendor, Model and Module as above, but clicking the "Play test sound" *does not produce any sound*! I do not get any sound from Gnome apps either. Expected Results: During installation (and subsequently), redhat-sound-config for *both* x86_64 and x86 FC3 reports soundcard as Vendor=Silicon, Model=Integrated Systems [SiS] Sound Controller, Module=snd-intel8x0, and clicking the "Play test sound" gives a perfect three-chord performance. Additional info: Using Up2Date to install the latest version of redhat-config-soundcard does not fix the problem.
This bug report is very similar to #137637.
Do you get any errors on the command-line? Is there a channel that you need to unmute (using alsamixer for example) in order to get sound out of the speakers on the x86 version? Does playing back a .wav using aplay work? Is esd running in the background?
Have you tried the aplay utility on x86?
