There are two levels to this; no sound, and weird sound.
The prime suspect when not getting *any* sound is having important channels muted. You may have several multiplicative channels that all affect output. For instance; I have a Master, a PCM and a Front channel. If I put them all at 50%, the end volume is Master*PCM*Front = 0.5*0.5*0.5 = 12.5%. So I always keep Front and PCM at 100%, and use Master to manage the output. Obviously, if even one is at 0%, I get 0% volume.
Open up 'alsamixer' in a terminal and make sure everything checks out. If you're using Pulseaudio, which is the default in Ubuntu 8.04 and later (but not in Kubuntu, for instance), make that 'alsamixer -Dhw' instead.
If you're having issues with the card not reacting when you connect headphones, see if there are *options* in your soundmixer. Some cards have options like Headphone Jack Detection, which you'd need to activate to get that behavior.
Failing all that, you may be able to solve it by specifying a model for your sound chipset. This is more the case of when you're getting sound but only from one speaker, the soundcard not detecting when you're connecting headphones (with no option to toggle this available), crackling sound or static, volume oddities, etc.
Basically, drivers aren't per-soundcard model but rather *per-chipset*. Furthermore, even though two different soundcards may be based on the same model of chipsets, they can have quirks caused by other factors involved in its making. Perhaps all BrandX cards based on ChipsetA have a slightly different revision of that chipset than BrandY's cards do, so their drivers' code need to differ slightly. Even though your computer senses it's based on ChipsetA, it doesn't know if it has BrandX's or BrandY's quirks, and you can end up with weird stuff when what it defaults to isn't right for your card. While it might very well be what another user with a BrandZ card, also based on ChipsetA, needs.
A more concrete example would be channels; perhaps ChipsetA technically supports having up to 5 channels (two front, two back, center), but the default cheapo ChipsetA cards only support two (left, right). You bought an expensive ChipsetA card, however, and you want all your 5 channels. But the driver only gives you the default two unless explicitly told your card supports more. You get the idea.
At this point you may want to consider manually upgrading ALSA. There is a neat script for this written by soundcheck. Newer versions just may be able to detect which quirks are needed automagically. If that doesn't help or if you don't want to, then read on.
Enter this command to find out which chipset your card is based on.
It'll say something like:
Code:
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC883 Analog [ALC883 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #
...where the ALC883 part is the chipset name, and what you want to find out. Find the entry for that chipset in the below list, and note the available models.
Note: This list is available for offline reading in /usr/share/doc/alsa-base/driver/ALSA-Configuration.txt.gz. The contents of it also differ between versions of ALSA.
This post focuses on Intel HDA cards. If you don't have one such but you're experiencing the same-ish issues, open up that ALSA-Configuration.txt.gz file and see if your chipset is listed there. The rest of the post should apply regardless.
Code:
Module snd-hda-intel
--------------------
Module for Intel HD Audio (ICH6, ICH6M, ESB2, ICH7, ICH8),
ATI SB450, SB600, RS600,
VIA VT8251/VT8237A,
SIS966, ULI M5461
[Multiple options for each card instance]
model - force the model name
position_fix - Fix DMA pointer (0 = auto, 1 = use LPIB, 2 = POSBUF)
probe_mask - Bitmask to probe codecs (default = -1, meaning all slots)
bdl_pos_adj - Specifies the DMA IRQ timing delay in samples.
Passing -1 will make the driver to choose the appropriate
value based on the controller chip.
[Single (global) options]
single_cmd - Use single immediate commands to communicate with
codecs (for debugging only)
enable_msi - Enable Message Signaled Interrupt (MSI) (default = off)
power_save - Automatic power-saving timtout (in second, 0 =
disable)
power_save_controller - Reset HD-audio controller in power-saving mode
(default = on)
This module supports multiple cards and autoprobe.
Each codec may have a model table for different configurations.
If your machine isn't listed there, the default (usually minimal)
configuration is set up. You can pass "model=<name>" option to
specify a certain model in such a case. There are different
models depending on the codec chip.

The model name "genric" is treated as a special case. When this
model is given, the driver uses the generic codec parser without
"codec-patch". It's sometimes good for testing and debugging.
If the default configuration doesn't work and one of the above
matches with your device, report it together with the PCI
subsystem ID (output of "lspci -nv") to ALSA BTS or alsa-devel
ML (see the section "Links and Addresses").
power_save and power_save_controller options are for power-saving
mode. See powersave.txt for details.
Note 2: If you get click noises on output, try the module option
position_fix=1 or 2. position_fix=1 will use the SD_LPIB
register value without FIFO size correction as the current
DMA pointer. position_fix=2 will make the driver to use
the position buffer instead of reading SD_LPIB register.
(Usually SD_LPLIB register is more accurate than the
position buffer.)
NB: If you get many "azx_get_response timeout" messages at
loading, it's likely a problem of interrupts (e.g. ACPI irq
routing). Try to boot with options like "pci=noacpi". Also, you
can try "single_cmd=1" module option. This will switch the
communication method between HDA controller and codecs to the
single immediate commands instead of CORB/RIRB. Basically, the
single command mode is provided only for BIOS, and you won't get
unsolicited events, too. But, at least, this works independently
from the irq. Remember this is a last resort, and should be
avoided as much as possible...
MORE NOTES ON "azx_get_response timeout" PROBLEMS:
On some hardwares, you may need to add a proper probe_mask option
to avoid the "azx_get_response timeout" problem above, instead.
This occurs when the access to non-existing or non-working codec slot
(likely a modem one) causes a stall of the communication via HD-audio
bus. You can see which codec slots are probed by enabling
CONFIG_SND_DEBUG_VERBOSE, or simply from the file name of the codec
proc files. Then limit the slots to probe by probe_mask option.
For example, probe_mask=1 means to probe only the first slot, and
probe_mask=4 means only the third slot.
The power-management is supported.
Open /etc/modprobe.d/alsa-base.conf up in a text editor with superuser permissions, such as by running 'gksu gedit /etc/modprobe.d/alsa-base.conf' in a run box (Alt+F2), or 'kdesudo kate /etc/modprobe.d/alsa-base.conf' if running Kubuntu. Then add a line to the bottom of that file as below, replacing <model> with a model that was listed as available to your chipset.
Code:
options snd-hda-intel model=<model>
As my example of 'aplay -l' showed earlier, I have a soundcard with an ALC883 chipset. As such, on my Acer laptop I made it 'model=acer', since the name of that model was something of an obvious giveaway.
Note that acer was one of the available ALC883 models! Which chipset you have takes priority of any hint you may find in the model names. If you have an ASUS ImaginaryModel 9999 laptop with an ALC883 chipset, you'll quickly notice that there are no asus models available for that chipset. "But, there's an asus available in ALC861; I'll use that instead!", you may think, and you'll eventually only solve your issues by pure luck and chance.
In my case, after that it worked; sound from both speakers and headphone jack detection. Refer to the list entries for your chipset to see which models are available to you. Obviously, if one strikes you as immediately suspicious (Acer and acer, Dell and dell, number of jacks, SPDIF or no SPDIF, etc), that could just be the one, if available in your chipset's list. Try one, then do a complete system restart to see if it worked.
Note: The following *may* be possible if you don't want to reboot (who does?). Omit the 'pulseaudio' lines if you're not using that. You're not if you're running Kubuntu.
Code:
$ pulseaudio -k
$ sudo service alsa-utils stop
$ sudo modprobe -r snd_hda_intel
$ sudo modprobe snd-hda-intel
$ sudo service alsa-utils start
$ pulseaudio -D
All in one line, for your copy/paste pleasure:
pulseaudio -k && sudo service alsa-utils stop && sudo modprobe -r snd_hda_intel && sudo modprobe snd-hda-intel && sudo service alsa-utils start && pulseaudio -D
Start playing something, connect/disconnect headphones, etc. If the model was not appropriate for your card, you may even have introduced issues you didn't have before, so give it a good and thorough testing. Open up a mixer (alsamixer, gnome-alsamixer, kmix, etc) and pay special attention to muted channels (as always) and *options*. Some chipset models have options such as Headphone Jack Detection, and if your original problem was that your speakers kept on blaring even though you had headphones plugged in, you could have just "unlocked" that setting, and you'd just need to realize it's there, find it, and enable it.
If it didn't work, change it to something else from that list and give it another go.
Failing THAT too, your best bet would be to replace ALSA with OSS 4. It is now licensed under the GPL, so if you place great weight on freedom then you're no longer barred by it being binary only. It's not old and deprecated either, contrary to common misconception; the old OSS3 included in the kernel, however, is. That is essentially a development snapshot from 10 years ago, and OSS has been (commercially) developed ever since.
Unlike the Linux-specific ALSA, it's a portable architecture, "available in 11 major Unix-like operating systems"[1]. As such, an application written to use OSS can be recompiled to work with Solaris and BSD-based systems, whereas ALSA is still Advanced Linux Sound Architecture.
There's a guide here on how to install it, and an interesting developer journal entry on the subject here. Oh, and an older blog post by the maintainer of OSS here, though written before it was licensed under the GPL.
Do note, OSS does not (at the time of writing) work with Pulseaudio.
