Sound recording & output to headphones on acer extensa 5220

Postby davybaby on Fri Feb 08, 2008 4:12 pm

After years of using (open)suse I decided to try linuxMint about a fortnight ago.
Phantastic! Easy to install, easy to use out of the box and recognises more hardware than opensuse does!
But... I still have two problems with sound
- I can't get sound recorder or audacity to record anything
- There is no sound on the headphones
Do I need to become an expert in jackd or some such, or ... is there a simple answer.

PS: please delete this if it's in the wrong place - it's my first post and I haven't learned the etiquette yet

Hi and welcome,
first the most obvious question: are you familiar with the software that you are using to record? have you try another program?

from what source are you truing to record (mic, line in aux.....)??
do you get any sound at all when you try to record?

Thanks for the fast reply. Currently my main focus is capturing the sound which can be heard on the system speakers.

I'm very familiar with audacity. I also tried the sound recorder (pre-installed) application - it's easy to understand though I never used it in the past. The result is always the same. The best I get is white noise with a different amplitude on the left and right channel.

Sorry for the late reply lot's of work and little fun in Feb :-((

I've already checked the volume settings.

Volume control works. The device and track to control are HDA Intel (Alsa Mixer) and master -- alternative device is Realtek ID 268 (OSS mixer).

All volume controls (Master, PCM and Digital) are at max.

Hi!
I've got an Extensa 5220 the other day and installed Mint 4.0 KDE. Soon after, I also discovered that my front headphone jack was dead.
So I looked through a couple of forums and at the end of the day, these are the things I did to get the headphones successfully working:

1.) Install ncurses-dev. It's needed to compile the alsa-utils later on. To do this from terminal, type:

sudo apt-get install libncurses5-dev build-essential linux-source linux-headers ncurses gcc automake autoconf gettext

2.) Download the latest stable alsa driver, lib and utils files from http://alsa-project.org/main/index.php/Main_Page . As I write this, the latest files are the 1.0.16 ones, so I downloaded:
ftp://ftp.alsa-project.org/pub/driver/a ... 16.tar.bz2
ftp://ftp.alsa-project.org/pub/lib/alsa ... 16.tar.bz2
ftp://ftp.alsa-project.org/pub/utils/al ... 16.tar.bz2

3.) Now unpack, prepare and install all of these. Here's how to do this from terminal:

tar xjf alsa-driver-1.0.16.tar.bz2
tar xjf alsa-lib-1.0.16.tar.bz2
tar xjf alsa-utils-1.0.16.tar.bz2

cd alsa-driver-1.0.16
sudo ./configure --with-cards=hda-intel
sudo make
sudo make install

cd ../alsa-lib-1.0.16
sudo ./configure
sudo make
sudo make install

cd ../alsa-utils-lib-1.0.16
sudo ./configure
sudo make install

# Note that no "sudo make" is necessary for the utils, but they will need the ncurses-dev installed (see paragraph 1) to compile.

4.)Add the line "options snd-hda-intel model=acer" to the file "/etc/modprobe.d/alsa-base". To do this from terminal, type:
kdesu kwrite /etc/modprobe.d/alsa-base

# Now add a this new line to the end of the document:
options snd-hda-intel model=acer
# Save and close the file.

5.) Reboot and - hopefully - enjoy your working headphone jack.

Thanks - I hadn't read my posts for some time and by chance found exactly this solution on Thursday. Headphones and mike from front panel now work perfectly.

The only problem that remains is getting the sound playing on the speakers (or headphone) to record. Neither audacity nor sound recorded can record regardless of which device and which input source I choose. Does anyone have any ideas on that?
