[PATCH] Line In for Acer Inspire 6530G model

[PATCH] Line In for Acer Inspire 6530G model

[Tony Vroon]

The Line In connector is set up as PIN_IN by default, using 
VREF_HIZ. It is connected to both ADCs, so add it to both 
input selectors.
Also add the ability to use the input mix (on a SoundBlaster 
one would call this "What You Hear").

I applied this as this appears safe.
Emilio, could you check whether this works?

I don't have the necessary cable to connect my MP3/CD Player to line
in, sorry. Unless I can use a normal mic on line in (I guess not,
because mics don't have any power supply), I won't be able to test.

Some time ago I was the one to (wrongly, it seems) report the 6530G to
work with the 4930 model. My problem was not being able to use the
internal mic for audioconference, which that model fixed. I didn't put
any attention into the "tuba" thing (I suspected it to be a marketing
thing, with the bass speaker tied to one of the two stereo channels).

I've been reading the thread, and I think I'll be able to test the
line-in issue. But I'm a bit confused about where to get the latest
driver snapshot package. Could you please provide a link to it, so
that I can get it running on my Ubuntu 9.04 installation?


Best regards,

   Juan Jesus.

The alsa-driver snapshot tarball can be found at
  ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-snapshot.tar.gz

There seems some script for Ubuntu to adapt that tree automatically,
but I don't remember exactly as I'm no Ubuntu user :)


HTH,

Wow!

I installed the snapshot, rebooted, plugged in both a CD player into
the line in and an external mic, launched

   (arecord | aplay) &

and then started playing with the alsamixer controls.

I can confirm that pluggin in headphones mute all the speakers. Also
the LFE level controls the bass speaker correctly.

I played with the "Capture" / "Input Source" pair of controls, and can
confirm that "Internal Mic", "External Mic" and "Line In" work ok. I'm
not sure about how to test the "CD" and "Input Mix" options.

I couldn't do anything about "Capture 1" / "Input Source 1". Has it
anything to do with the second capture device I get from arecord -l?


skandalfo@rimmer:~$ arecord -l
**** Lista de CAPTURE Dispositivos Hardware ****
tarjeta 0: SB [HDA ATI SB], dispositivo 0: ALC888 Analog [ALC888 Analog]
  Subdispositivos: 1/1
  Subdispositivo #0: subdevice #0
tarjeta 0: SB [HDA ATI SB], dispositivo 2: ALC888 Analog [ALC888 Analog]
  Subdispositivos: 1/1
  Subdispositivo #0: subdevice #0


I tried to perform the same tests with arecord -Dhw:0,2 but it
complained about no appropriate sample format, so I suppose I was
trying something stupid.


In any case, congratulations, and lots of thanks for your good work.
My laptop now sounds much better :-D


Best regards,

   Juan Jesus.

can't find snd_card_next!

[Guilherme]

Hi all!

I studing the aplay program and there is a function that I can't find in 
any header.
Ive tried asound.h and asoundlib.h among other but without success!

This is the code:

    card = -1;
    if (snd_card_next(&card) < 0 || card < 0) {
        error(_("no soundcards found..."));
        return;
    }

Where is the snd_card_next() function?

Thanks all!

Tks!

$ grep snd_card_next /usr/include/alsa/*
/usr/include/alsa/control.h:int snd_card_next(int *card);
