no sound in kubuntu 7.10

Hi all, I'm new to kubuntu, and i quite like it, but I have a huge problem. I can't get any sound out of my laptop. My laptop is an Acer 6920g. This is the output of both lspci and lsmod: [quote='lsmod'] Module Size Used by aes 28608 3 af_packet 24840 4 nls_iso8859_1 5120 1 nls_cp437 6784 1 vfat 14080 1 fat 54300 1 vfat usb_storage 73024 1 ide_core 116804 1 usb_storage libusual 18448 1 usb_storage ipv6 273892 12 rfcomm 42136 2 l2cap 26240 11 rfcomm bluetooth 57060 4 rfcomm,l2cap ppdev 10244 0 acpi_cpufreq 10568 1 cpufreq_conservative 8072 0 cpufreq_ondemand 9612 1 cpufreq_powersave 2688 0 cpufreq_userspace 5280 0 cpufreq_stats 7232 0 freq_table 5792 3 acpi_cpufreq,cpufreq_ondemand,cpufreq_stats container 5504 0 battery 11012 0 button 8976 0 ac 6148 0 video 18060 0 sbs 19592 0 dock 10656 0 parport_pc 37412 0 lp 12580 0 parport 37448 3 ppdev,parport_pc,lp arc4 2944 2 ecb 4608 2 joydev 11328 0 blkcipher 7556 1 ecb snd_hda_intel 263712 2 snd_pcm_oss 44672 0 snd_mixer_oss 17664 1 snd_pcm_oss snd_pcm 80388 2 snd_hda_intel,snd_pcm_oss snd_seq_dummy 4740 0 snd_seq_oss 33152 0 snd_seq_midi 9600 0 snd_rawmidi 25728 1 snd_seq_midi uvcvideo 48644 0 snd_seq_midi_event 8448 2 snd_seq_oss,snd_seq_midi compat_ioctl32 2304 1 uvcvideo videodev 29312 1 uvcvideo v4l1_compat 15364 2 uvcvideo,videodev v4l2_common 18432 2 uvcvideo,videodev snd_seq 53232 6 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_seq_midi_event sr_mod 17828 0 cdrom 37536 1 sr_mod snd_timer 24324 2 snd_pcm,snd_seq snd_seq_device 9228 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_rawmidi,snd_seq iwl4965 101480 0 iwlwifi_mac80211 175112 1 iwl4965 cfg80211 7304 1 iwlwifi_mac80211 i2c_core 26112 0 snd 54660 13 snd_hda_intel,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_seq_oss,snd_rawmidi,snd_seq,snd_timer,snd_seq_device soundcore 8800 1 snd serio_raw 8068 0 intel_agp 25620 0 agpgart 35016 1 intel_agp psmouse 39952 0 shpchp 34580 0 pci_hotplug 32704 1 shpchp snd_page_alloc 11400 2 snd_hda_intel,snd_pcm evdev 11136 6 ext3 133896 1 jbd 60456 1 ext3 mbcache 9732 1 ext3 usbhid 29536 0 hid 28928 1 usbhid sg 36764 0 sd_mod 30336 7 ata_piix 17540 0 ahci 23300 4 ata_generic 8452 0 ehci_hcd 36492 0 uhci_hcd 26640 0 libata 125168 3 ata_piix,ahci,ata_generic scsi_mod 147084 5 usb_storage,sr_mod,sg,sd_mod,libata usbcore 138632 7 usb_storage,libusual,uvcvideo,usbhid,ehci_hcd,uhci_hcd thermal 14344 0 processor 32072 2 acpi_cpufreq,thermal fan 5764 0 fuse 47124 5 apparmor 40728 0 commoncap 8320 1 apparmor[/quote] [quote='lspci'] 00:00.0 Host bridge: Intel Corporation Mobile PM965/GM965/GL960 Memory Controller Hub (rev 03) 00:01.0 PCI bridge: Intel Corporation Mobile PM965/GM965/GL960 PCI Express Root Port (rev 03) 00:1a.0 USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Contoller #4 (rev 03) 00:1a.1 USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #5 (rev 03) 00:1a.7 USB Controller: Intel Corporation 82801H (ICH8 Family) USB2 EHCI Controller #2 (rev 03) 00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03) 00:1c.0 PCI bridge: Intel Corporation 82801H (ICH8 Family) PCI Express Port 1 (rev 03) 00:1c.1 PCI bridge: Intel Corporation 82801H (ICH8 Family) PCI Express Port 2 (rev 03) 00:1c.2 PCI bridge: Intel Corporation 82801H (ICH8 Family) PCI Express Port 3 (rev 03) 00:1c.3 PCI bridge: Intel Corporation 82801H (ICH8 Family) PCI Express Port 4 (rev 03) 00:1c.4 PCI bridge: Intel Corporation 82801H (ICH8 Family) PCI Express Port 5 (rev 03) 00:1d.0 USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #1 (rev 03) 00:1d.1 USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #2 (rev 03) 00:1d.2 USB Controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #3 (rev 03) 00:1d.7 USB Controller: Intel Corporation 82801H (ICH8 Family) USB2 EHCI Controller #1 (rev 03) 00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev f3) 00:1f.0 ISA bridge: Intel Corporation 82801HEM (ICH8M) LPC Interface Controller (rev 03) 00:1f.1 IDE interface: Intel Corporation 82801HBM/HEM (ICH8M/ICH8M-E) IDE Controller (rev 03) 00:1f.2 SATA controller: Intel Corporation 82801HBM/HEM (ICH8M/ICH8M-E) SATA AHCI Controller (rev 03) 00:1f.3 SMBus: Intel Corporation 82801H (ICH8 Family) SMBus Controller (rev 03) 01:00.0 VGA compatible controller: nVidia Corporation Unknown device 0405 (rev a1) 02:00.0 Ethernet controller: Attansic Technology Corp.

This is the section in the bugfix that shows how to get sound. I would read through the whole thread though to get a better understanding of how everything turns out cuz I didn't read the whole thing. Instructions that work for me: sudo apt-get install alsa-source cd /usr/src/ sudo tar xvjf alsa-driver.tar.bz2 cd modules/alsa-driver/ sudo ./configure --with-kernel=/usr/src/linux-headers-$(uname -r) --with-cards=hda-intel --with-oss=yes cd alsa-kernel sudo patch -p1 ... # repeat with all three patches cd .. sudo make sudo make install Now either reboot or reload all sound modules: killall mixer_applet2 && sudo modprobe -r snd-hda-intel sudo rmmod snd-seq-dummy snd-seq-oss snd-seq-midi snd-pcm-oss sudo rmmod snd-mixer-oss snd-pcm snd-hwdep snd-rawmidi snd-seq-midi-event sudo rmmod snd-page-alloc snd-seq sudo rmmod snd-timer snd-seq-device sudo rmmod snd sudo rmmod soundcore sudo depmod -a sudo modprobe snd-hda-intel Finally, use alsamixer to unmute the headphones & internal speakers, and set PCM volume to something louder than 0%.

I don't realy understand how to install the patch. Where do I find "alsa-driver.tar.bz2"? I do need it to install the patch, right? This afternoon, I descovered somthing strange. I touched the volume control of the cinedash panel on my acer laptop, and a volume bar appears on the screen, saying the volume is on 11%. In the sound settings screen, all sounds were set to 100%. (11% is the maximum volume. At that point, the cinedash panel's volume meter is full.)

I used kubuntu 7.10, but i reinstalled ubuntu this afternoon, and updated to 8.04, but still no sound. If I right-click on the speaker icon, and choose preferences, "HDA Intel (Alsa Mixer)" is already selected. My laptop is not in the list u posted.
