Dear List, After some googling around without any results, I'm quite puzzled. Since some past update I can't precise, kernel 2.6.164 works fine, however 2.6.194 has some sound problem in my somewhat old and beaten Toshiba laptop. -Audacious plays OK but other applications have problems. -For instance, mplayer acts quirky: when I pause a playing video, sound keeps stuttering endlessly. The same happens sometimes when I close mplayer window. -system-config-soundcard detects the card and starts to play sample but stuttering all the way, repeating every 4th of a second or so some 16 times, at about a 1/2 second rate. -Youtube has no sound! -Software volume control has been lost long ago, unrelated to this problem but interested in recovery anyway System is fully up to date. Any hints will be appreciated! Some relevant lines in my /etc/modprobe.conf as is now, with some scars left after unfruitful battles: alias snd-card-0 snd-hda-intel #options snd-card-0 index=0 #options snd-hda-intel index=0 remove snd-hda-intel { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-hda-intel options snd-hda-intel model=auto options snd-hda-intel probe_mask=1 options snd cards_limit=8 getinfo.sh output: == BEGIN uname -rmi == 2.6.18-194.8.1.el5 i686 i386 == END uname -rmi == == BEGIN rpm -q centos-release == centos-release-5-5.el5.centos == END rpm -q centos-release == == BEGIN getenforce == Disabled == END getenforce == == BEGIN rpm -qa kernel\* | sort == kernel-2.6.18-164.15.1.el5 kernel-2.6.18-194.3.1.el5 kernel-2.6.18-194.8.1.el5 kernel-devel-2.6.18-164.15.1.el5 kernel-devel-2.6.18-194.3.1.el5 kernel-devel-2.6.18-194.8.1.el5 kernel-headers-2.6.18-194.8.1.el5 == END rpm -qa kernel\* | sort == == BEGIN lspci == 00:00.0 Host bridge: Intel Corporation Mobile 915GM/PM/GMS/910GML Express Proces sor to DRAM Controller (rev 03) 00:01.0 PCI bridge: Intel Corporation Mobile 915GM/PM Express PCI Express Root P ort (rev 03) 00:1b.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 04) 00:1c.0 PCI bridge: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) PCI Ex press Port 1 (rev 04) 00:1c.1 PCI bridge: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) PCI Ex press Port 2 (rev 04) 00:1d.0 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) US B UHCI #1 (rev 04) 00:1d.1 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) US B UHCI #2 (rev 04) 00:1d.2 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) US B UHCI #3 (rev 04) 00:1d.3 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) US B UHCI #4 (rev 04) 00:1d.7 USB Controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) US B2 EHCI Controller (rev 04) 00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev d4) 00:1f.0 ISA bridge: Intel Corporation 82801FBM (ICH6M) LPC Interface Bridge (rev 04) 00:1f.2 IDE interface: Intel Corporation 82801FBM (ICH6M) SATA Controller (rev 0 4) 01:00.0 VGA compatible controller: ATI Technologies Inc M24 [Radeon Mobility X60 0] 02:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8036 PCI-E Fast Et hernet Controller (rev 10) 06:04.0 Network controller: Intel Corporation PRO/Wireless 2200BG [Calexico2] Ne twork Connection (rev 05) 06:06.0 CardBus bridge: Texas Instruments PCIxx12 Cardbus Controller 06:06.1 FireWire (IEEE 1394): Texas Instruments PCIxx12 OHCI Compliant IEEE 1394 Host Controller 06:06.2 Mass storage controller: Texas Instruments 5-in-1 Multimedia Card Reader (SD/MMC/MS/MS PRO/xD) 06:06.3 SD Host controller: Texas Instruments PCIxx12 SDA Standard Compliant SD Host Controller == END lspci == == BEGIN lspci -n == 00:00.0 0600: 8086:2590 (rev 03) 00:01.0 0604: 8086:2591 (rev 03) 00:1b.0 0403: 8086:2668 (rev 04) 00:1c.0 0604: 8086:2660 (rev 04) 00:1c.1 0604: 8086:2662 (rev 04) 00:1d.0 0c03: 8086:2658 (rev 04) 00:1d.1 0c03: 8086:2659 (rev 04) 00:1d.2 0c03: 8086:265a (rev 04) 00:1d.3 0c03: 8086:265b (rev 04) 00:1d.7 0c03: 8086:265c (rev 04) 00:1e.0 0604: 8086:2448 (rev d4) 00:1f.0 0601: 8086:2641 (rev 04) 00:1f.2 0101: 8086:2653 (rev 04) 01:00.0 0300: 1002:5462 02:00.0 0200: 11ab:4351 (rev 10) 06:04.0 0280: 8086:4220 (rev 05) 06:06.0 0607: 104c:8039 06:06.1 0c00: 104c:803a 06:06.2 0180: 104c:803b 06:06.3 0805: 104c:803c == END lspci -n == -- Eduardo Grosclaude Universidad Nacional del Comahue Neuquen, Argentina -------------- next part -------------- An HTML attachment was scrubbed...
