Red Hat Bugzilla – Bug 117461
(ALSA NM256)no sound on SONY PCG-F360
Last modified: 2015-01-04 17:04:51 EST
Description of problem:
No sound udible on system since loading FC2-test1. Drivers all load
correctly, soundcard is detected, mixer controls appear to work, but
Version-Release number of selected component (if applicable):
Always. Got loop of partial sound one time only.
Steps to Reproduce:
Created attachment 98276 [details]
output of lspci -vv
Upgraded to kernel-2.6.3-2.1.238.i686.rpm...now system locks hard when
soundcard driver attempts to load under X (running the
soundcard-detection utility, as soon as you press "play test sound" it
locks up solid, must power off). Tried disabling ACPI and tried
pci=usepirqmask as recommended in boot messages. No change.
Upgraded to kernel-2.6.3-2.1.242 ... system no longer locks hard, but
still no sound.
be aware that ALSA defaults to a sound volume of zero; could you try
running alsa-mixer to increase sound ?
Yes, increasing sound I get either nothing or looping sound from the
test tones played by the soundcard detection routine.

output of dmesg from normal boot
Maybe this will help, it looks like maybe interrupts are not getting configured
properly. Bad BIOS?
Problem still exists on test-2. Volume Control applet reports "No
mixer device found" but I can run alsamixer from the commandline...it
shows _two_ mixer devices???
Fedora Core 2 Test 2 same problem on Compaq Armada E500, Device
information is ES1978 Maestro 2E, driver snd-es1960. output from
running alsamixer at command line -> "alsamixer: function
snd_ctl_open failed for default: No such device". when attempting to
icrease the volume control on the panel the volume bar automatically
returns to the bottom.
kernel-2.6.5-1.315 I can get the test sound if I setenforce 0 and I
run the soundcard detection from the command line as root...
The volume control applet still forces everything back to zero volume
and I can't seem to get any sound out of the CD drive either...
did this get fixed with the latest updates ?
This machine is now running FC3. Last time I tested sound worked if OSS
compatible devices were used. Native ALSA didn't work.
Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat. The Fedora legacy project will be producing further kernel
updates for security problems only.
If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.
