At least with some distribution releases, the ALSA loopback
module doesn't work well.  For example, with Mageia 1 it worked
perfectly.  Then, with Mageia 2, it has severe xruns, both with
net-JACK and with only aplay and arecord.  Evidence suggests the
loopback module accepts samples too rapidly from the sending
client, which overruns the buffer of the receiving client.

I asked here a while ago if there were solutions.  Yes, I ought
to file a bug report if I could scrape together a few minutes to
do so.

Re: [Alsa-user] recording audio from speakers

2013-07-29 Thread YuGiOhJCJ Mailing-List 
When I speak about jack, I speak about the hardware, not the software.
So, I have never used the jack software.
When I use alsaloop, I do this:
$ alsaloop -C hw:0,0 -P hw:0,0 -t 5

After typing this command, I can hear in my headphones a looping noise.
So, I am not sure I am using it as I should.

Is it a normal behaviour ?

if you using jack you can configure alsa2jack emulation and use it
without loopback devices. You can route everything inside jack. Your
application will be visible in jack as native jack application. But
some applications works bad wtih alsa2jack emulation.

For me, it is the definitive solution. You can configure ALSA to use
the loopback device as first sound card, and use alsa_in and alsa_out,
or for a better sound quality, zita-ajbridge (zita-a2j and zita-j2a) to
interface jack and alsa.

That way, all the ALSA applications will use the loopback by default
and will be available in jack. Of course, you will have to run jack all
the time.

It is a  French how-to here:
http://www.linuxmao.org/TUTO+%3A+ALSA+vers+JACK&structure=Accueil+Logiciels
and another one here:
http://alsa.opensrc.org/Jack_and_Loopback_device_as_Alsa-to-Jack_bridge
but the alsa wiki seam to be down.

You can also use zita-*2* directly, but I did not try it. I prefer the
automatic way with the loopback device.

Re: [Alsa-user] Soundblaster Audigy 2 NX- Still buggy after all these years

2013-07-29 Thread Mark DM 
I am posting what I see ! Perhaps your interpretation is contradictory as
it appears to be with the alsa devs. The point being is that what I can
toggle with amixer and hardware mute on audigy or remote,  is not available
in any mixer control! You can say they are contradictory however what I
need is to change the mute/unmute behavior to conform to the hardware mute
method such as I use amixer for. Amixer is the ONLY available unmute method
when hardware mute is used on Audigy or remote.

I know the xbmc does a different mute because I programmed the xbmc mute on
the remote . Even when deactivated or when not running xbmc the
aforementioned hardware mute buttons behave differently than a software
mute


I have also created situations where the hardware mute is off and the
software mute is on and visa versa

The remote's and device's mute buttons work automatically.  Unmuting
must be handled by some software that listens for these events.

Obviously, nothing is actually listening.  Why do you think that XMBC
is configured for this?

As far as I know, the only software that can handle the Audigy 2 NX's
remote events is LIRC: .
(Use driver "alsa_usb" and remote "RM-1500".)

> Must always mute with: amixer -c 1 cset numid=5 0

Or just use "amixer -c1 cset numid=5 toggle".
