Bug Description

When doing the laptop tests with this laptop (HP Pavilion DV7) recording with the internal mic does work, but the end of the recording gets cut off.

What I find is that there is approximately a 1 second delay in the audio input. This means that it records an extra second at the start (background noise) and chops off an extra second at the end. The sound itself is time-shifted by approx 1 second.

Hi Andrew and thanks for reporting this bug. I have some additional questions:

1) You indicated that recording worked correctly when you filed the bug. Is this a problem with a particular program only - does recording work with other programs?

2) How much is cut off? Is it always the last second regardless of recording length, or always say 50% of the recording, or...?

I have the same laptop model and the same problem.

I have tired:
Ubuntu 10.04
Ubuntu 10.10
Kubuntu 10.10

I have tried both 32 bit and 64 bit versions of the OS.

This makes the computer completely and totally unusable for VoIP and similar applications -- which is *very* important to me.
When doing an echo-back test on VoIP all I get are random fragments of my speech and other noise. I suspect the echo-cancellation is preventing the delayed audio from getting through.

Sound output (internal and external speakers) works Great! I have not tested the HDMI audio out.

it is only the audio input that is not working.

I have tried the internal microphone,
the external microphone jack
and even tried a USB microphone/headset

all with the same result...

In the audio control panel, I can adjust the input volume and see the bars of audio level. I can adjust this to get reasonable sound level. Using the gnome-recorder I can get acceptable audio quality of record/playback, but the problem is the missing speech and the added time shift.

also some programs such as audicity will hang when trying to record sound. and other programs like the webcam video recorder run very slowly.

I have now tried natty 10.04 64 bit

which is supposed to be the latest and greatest....

and it totally does not work. at least with 10.10 I could actually record sound even if it does get cut off, but with 11.04 I can't even do that, I have no sound input at all.

I have also fiddled considerably with various config settings as outlined on a zillion different web pages of a zillion different people all trying to get the audio system to work properly with the Intel HDA chips -- which are apparently the new standard for all (most) new laptops being made. and it simply does not work, nothing I have tried yet, other than to remove PulseAudio actually gets me a usable audio system.

@codeslinger, thanks for the added comments. I've seen similar problems with this controller and another one in bug 741825, but this one seems more severe. Anyway, should we succeed in solving bug 741825 I'm hoping that these symptoms will stop as well.
