Hey DaniWeb,
I have downloaded the latest version of Ubuntu 8.04 and my sound is not working. Ubuntu is installed inside Windows Vista (it is the new cool feature of Ubuntu!). I am able to adjust the volume level but there's no volume at all!
This is a Lenovo 3000 Y410 Laptop running Windows Vista Home Premium.
RAM: 1.5GB
Processor: Intel Core 2 Duo T5250

Windows Vista uses the Realtek HD audio for sound. I checked the package online @ but that was of no help. Could anyone help me with the Sound Issue?

— common causes for "no sound" after a Hardy (8.04) install inside Windows (Wubi) are: the hardware is detected but the wrong device or channel is active, an HDA driver model quirk for the Realtek codec on Lenovo hardware, or mismatch between ALSA/PulseAudio/OSS for user apps. has already shown a model tweak can restore playback and that changing the input source fixed recording; for Skype they ended up using an OSS-compatibility route.

Useful diagnostics to collect locally (these show the card, available devices, kernel messages and a quick speaker test):

cat /proc/asound/cards
aplay -l
arecord -l
lspci -nnk | grep -iA3 audio
dmesg | egrep -i "hda|alsa|audio"
speaker-test -c2

Practical next steps without repeating earlier exact commands: verify all mixer channels and auto-mute settings (GUI or command-line mixer), confirm the kernel sees the Realtek HDA codec and which model strings the HDA driver accepts (kernel HD‑Audio model list in the ALSA/kernel docs). If the card is present but output is still wrong, try a model-specific driver option (many Lenovo/Realtek combos need one) or use the HDA jack-remapping tool included in alsa-tools. If the distro ALSA is old, upgrade ALSA or the kernel (backports/newer release) — many Realtek fixes landed after 8.04.

Skype and other legacy apps: older Skype builds expected OSS; bridge solutions or PulseAudio integration can be used so the app sees the right device. For deeper troubleshooting capture the ALSA debug info (alsa-info or equivalent) and the command outputs above to reference when applying driver/model fixes.

Give me the output of:

lsmod | grep snd

In Hardy (8.04) this worked for me, but did not in Gutsy (7.10):
sudo vi /etc/modprobe.d/alsa-base

Then add the following line at the end:
options snd-hda-intel model=lenovo

Also works:
options snd-hda-intel model=hp

BUT: still struggling with the microphone - does not work even in the Sound Recorder,

Was able to get recording working (but playback at lower volume): changed input source from Front Mic to ATAPI Mic (in alsamixer or Volume Control).

BUT: Test call fails in Skype (do not hear my voice palyed back). Skype suggests using OSS rather than ALSA or ALSA emulator for OSS. All I did was changing in System | Preferences | Sound | Sound capture to 'OSS - Open Sound System'. Maybe, more detailed changes required.

Final blow:

To make Skype working (with good playback from microphone recording) you should install alsa-oss package, then change command from skype to aoss skype

That's it.
