No sound on ubuntu dapper

Everything works quite well on ubuntu dapper, except I can't get any sound. No sound at start, nor when I want to lisetn to CD or anything.I am running ubuntu on VAIO VGN-B3VP. I have a an Intel 82801DB-ICH4 sound card that works ok on Mandriva Linux 2006.I surfed on the net a bit, not much I admit, but none of the solutions I found actually worked for me.when I type in console:<code>aplay -lI get:**** List of PLAYBACK Hardware Devices ****card 0: I82801DBICH4 [Intel 82801DB-ICH4], device 0: Intel ICH [Intel 82801DB-ICH4]  Subdevices: 0/1  Subdevice #0: subdevice #0card 0: I82801DBICH4 [Intel 82801DB-ICH4], device 4: Intel ICH - IEC958 [Intel 82801DB-ICH4 - IEC958]  Subdevices: 1/1</code>it seems ok for me so far.I have checked Multimedi Systems selector and both i/o are set to ALSA. I also checked alsamixer and everything seems fine. Though I don't have alsaconf but that shouldn't be the problem right?Also checed dmesg, /var/log/messages and /var/log/syslog but in none I can't find anything about any audio device or sound device or activity. Under /dev/ I have snd.here's my complete lsmod if it helps:Module                  Size  Used byrfcomm                 40216  0l2cap                  26244  5 rfcommbluetooth              50020  4 rfcomm,l2capsonypi                 23084  0ppdev                   9220  0i915                   20608  1drm                    73236  2 i915speedstep_centrino      8400  1cpufreq_userspace       4696  1cpufreq_stats           5636  0freq_table              4740  2 speedstep_centrino,cpufreq_statscpufreq_powersave       1920  0cpufreq_ondemand        6428  0cpufreq_conservative     7332  0video                  16260  0tc1100_wmi              6916  0sony_acpi               5644  0pcc_acpi               12416  0hotkey                 11556  0dev_acpi               11140  0container               4608  0button                  6672  0acpi_sbs               19980  0battery                 9988  1 acpi_sbsac                      5252  1 acpi_sbsi2c_acpi_ec             5120  1 acpi_sbsi2c_core               21904  1 i2c_acpi_ecipv6                  265728  6nls_utf8                2176  2ntfs                  103536  2dm_mod                 58936  1af_packet              22920  4md_mod                 72532  0sr_mod                 16932  0sbp2                   24196  0scsi_mod              139496  2 sr_mod,sbp2parport_pc             35780  0lp                     11844  0parport                36296  3 ppdev,parport_pc,lppcmcia                 40508  0joydev                 10048  0yenta_socket           28428  1rsrc_nonstatic         13440  1 yenta_socketpcmcia_core            42640  3 pcmcia,yenta_socket,rsrc_nonstatice100                   40580  0mii                     5888  1 e100ipw2200               107308  0usbhid                 39904  0ieee80211              37064  1 ipw2200ieee80211_crypt         6272  1 ieee80211ieee80211_1_1_13       38216  0ieee80211_1_1_13_crypt     6784  1 ieee80211_1_1_13tsdev                   8000  0snd_intel8x0           33692  3snd_ac97_codec         93216  1 snd_intel8x0snd_ac97_bus            2304  1 snd_ac97_codecsnd_pcm_oss            53664  0snd_mixer_oss          18688  1 snd_pcm_osshw_random               5652  0snd_pcm                89864  4 snd_intel8x0,snd_ac97_codec,snd_pcm_osssnd_timer              25220  2 snd_pcmsnd                    55268  10 snd_intel8x0,snd_ac97_codec,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timersoundcore              10208  1 sndsnd_page_alloc         10632  2 snd_intel8x0,snd_pcmpsmouse                36100  0rtc                    13492  0shpchp                 45632  0pci_hotplug            29236  1 shpchpserio_raw               7300  0intel_agp              22940  1agpgart                34888  3 drm,intel_agpevdev                   9856  2ext3                  135816  1jbd                    58772  1 ext3ide_generic             1536  0ehci_hcd               34184  0ohci1394               35124  0ieee1394              299832  2 sbp2,ohci1394uhci_hcd               33808  0usbcore               130820  4 usbhid,ehci_hcd,uhci_hcdide_cd                 33028  0cdrom                  38560  2 sr_mod,ide_cdide_disk               17664  5piix                   11012  1generic                 5124  0thermal                13576  0processor              23360  2 speedstep_centrino,thermalfan                     4868  0capability              5000  0commoncap               7296  1 capabilityvga16fb                13704  1vgastate               10368  1 vga16fbfbcon                  42784  72tileblit                2816  1 fbconfont                    8320  1 fbconbitblit                 6272 1 fbconsoftcursor              2304  1 bitblitI found this especially interesting:snd                    55268  10 snd_intel8x0,snd_ac97_codec,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer soundcore              10208  1 sndeverything seems ok.the funny thing is also when I try:lspci | fgrep 'audio'i got0000:00:1f.5 Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 03)which seems fine too.I really don't know what could be the problem so can anyone give me a tip?tnx

Here is what I did (and posted to the Ubuntux forum, 2006-01-31). Hope it helps you, too.

With the updates of 1/31/06, Dapper Drake now produces sound on my Gateway 3550GZ. Very cool.

Thanks, update gods.

Addendum: I went back to Ubuntu Breezy 5.10 and, of course lost all sound. So I renewed my struggles. Here is the solution that I posted elsewhere.

*********************

I have the Gateway 3550GZ (same as M210?) and have struggled with the lack of sound for weeks (on Ubuntu 5.10). A thread at on another forum helped immensely. The advice was spot on.

1. Put a CD into the drive and play some music. You can verify it by running Volume Monitor in Sound and Video Applications (Gnome) . I saw activity on the monitor but could not hear any music.

2. Open Volume Control (aka Alsa Mixer --- again, in Sound and Video Applications).

3. Under "File" select "Change Device" to confirm that the selected device is "Intel 82801DB-ICH4 (Alsa Mixer)"

4. Unmute every control in "Playback" and "Capture" and, where possible, put the slider control somewhere in the middle for every output and input.

4. Under "Switches" uncheck "Headphone Jack Sense," "Line Jack Sense," and "External Amplifier."

5. Enjoy the music.

Don't know if this will work on other machines/distros/ALSA versions (Gateway 350GZ, Ubuntu Breezy Badger, ALSA 1.0.9, here) but the crucial element was getting all three toggles turned off. If any of them are "on" --> no sound.

*****************************

I should add that the Gateway uses the AD1981B sound chip. Yours may differ, but this worked for me.

This works for my vaio VGN-B3XP (82801DB-ICH4) running Dapper. Phew. At first I could not find the 'Switches' option in "Volume Control". I ended up turning everything on in Edit->preferences, and the 'Switches' option appeared.
