Ubuntu 7.04 on Amilo Li 1705 problem

[blagojedrovski]

Hi, sorry for my poor English. it's a great honor to be a part of this forum, i have just installed Ubuntu 7.04 and absolutely fell in love with it. Instalation went great, Ubuntu booted and i thought everything went well.

My problems are theese:

1. My resolution is stuck in 800x600 mode, and somehow can't change it... I've searched in many forums, found drivers on viaarena.com but they can't be installed, since either i'm being a major jackass (because im used to work in windows enviroment) and doing something wrong or i simply can't understand what to do I also came across "dpkg-reconfigure xserver-xorg" command (not sure about spelling it right) and after 3 long long hours of changing xorg.config file somehow managed to fix my resolution but my lame "CN896 VIA Chrome9™" integrated graphics videocard isn't working correctly (works only with the vesa driver)...

2. My sound card which works on my laptop speaker, but when i plug in my headphones it stops, i take my headphones out, it works again (funny huh)... Btw VIA HD Audio Codec VT1708 paired with VT8237A

As i said http://www.viaarena.com/default.aspx...Type=3&OSID=45 has drivers for almoust everything i need but i can't install them. Can someone PLEASE PLEASE PLEASE help me out a bit, this is one hell of an operating system and i intend to learn more and more about it!

Thank You In Advance!!!

Do you mean to say that there is no sound also on the headphones when you plug in the headphones? Otherwise i think this is a quite usual behavior, when you plug in the headphones the output to the speaker will automatically stop (but of course you should be able to hear something with the headphones)
Otherwise some laptops have lots of different switches for the audio card. You can see these switches if you open the mixer window. One laptop i used had a switch "headphone sense", and this would enable or disable the automatically muting of the speakers when the headphones are inserted. Maybe you can find some setting there.

I had the same problem and found the solution which works me:

You must patch the hda_codec.c in alsa-driver sources, recompile and install:

That's all

I got it to work as well !

the main steps are the following :

Download the latest alsa driver

tar -xvjf alsa-driver-1.x.xx.tar.bz2

open alsa-kernel/pci/hda/patch_via.c

change

static int patch_vt1708(struct hda_codec *codec)
{
	struct via_spec *spec;
	int err;

	/* create a codec specific record */
	spec = kcalloc(1, sizeof(*spec), GFP_KERNEL);
	if (spec == NULL)
		return -ENOMEM;

	codec->spec = spec;


	/* automatic parse from the BIOS config */
	err = vt1708_parse_auto_config(codec);
	if (err < 0) {
		via_free(codec);
		return err;
	} else if (!err) {
		printk(KERN_INFO "hda_codec: Cannot set up configuration "
		       "from BIOS.  Using genenic mode...\n");
	}

	
	spec->stream_name_analog = "VT1708 Analog";
	spec->stream_analog_playback = &vt1708_pcm_analog_playback;
	spec->stream_analog_capture = &vt1708_pcm_analog_capture;

	spec->stream_name_digital = "VT1708 Digital";
	spec->stream_digital_playback = &vt1708_pcm_digital_playback;
	spec->stream_digital_capture = &vt1708_pcm_digital_capture;

	
	if (!spec->adc_nids && spec->input_mux) {
		spec->adc_nids = vt1708_adc_nids;
		spec->num_adc_nids = ARRAY_SIZE(vt1708_adc_nids);
		spec->mixers[spec->num_mixers] = vt1708_capture_mixer;
		spec->num_mixers++;
	}

	codec->patch_ops = via_patch_ops;

	codec->patch_ops.init = via_auto_init;
#ifdef CONFIG_SND_HDA_POWER_SAVE
	spec->loopback.amplist = vt1708_loopbacks;
#endif

	return 0;
}

by :

static int patch_vt1708(struct hda_codec *codec)
{
	unsigned int pin_hp; 
	struct via_spec *spec;
	int err;

	/* create a codec specific record */
	spec = kcalloc(1, sizeof(*spec), GFP_KERNEL);
	if (spec == NULL)
		return -ENOMEM;

	codec->spec = spec;

	/* Ajout SQ071031 */

	pin_hp=pin_hp&0x3FFFFFFF;
	snd_hda_codec_write(codec, 0x20, 0, AC_VERB_SET_CONFIG_DEFAULT_BYTES_3, pin_hp>>24); 


	/* automatic parse from the BIOS config */
	err = vt1708_parse_auto_config(codec);

		return err;

		spec->num_adc_nids = ARRAY_SIZE(vt1708_adc_nids);
		spec->mixers[spec->num_mixers] = vt1708_capture_mixer;
		spec->num_mixers++;
	}

	codec->patch_ops = via_patch_ops;

	codec->patch_ops.init = via_auto_init;
#ifdef CONFIG_SND_HDA_POWER_SAVE
	spec->loopback.amplist = vt1708_loopbacks;
#endif

	return 0;
}

now, in order to compile :

cd alsa-driver-1.xx.xx
./configure
make
sudo make install

Reboot and that should work fine.

I am so sorry for not responding for such a long time, i've had soo many work this past weeks it was impossible to have some spare time... Anyway THANK YOU a lot, i've done what you told me and it's all working now... Just love the 7.04 version

[oreja]

I found the solution which works witch Amilo Pro (Fujitsu Siemens)
You have to add two lines to file /etc/modprobe.d/alsa-base

//add this lines
options snd-hda-intel model=3stack enable=yes
options snd-hda-intel model=auto position_fix=1 enable=yes

and restart laptop. I hope it helps.

Has anyone test the hardware on 8.04 yet??

[gnuslov]

I have an everex gbook va1500v, which has the same sound hardware as the poster that started the thread, and I can report than squil's patch to alsa-drivers works on 8.04, but ONLY if you remove the alsa-driver folder from your /lib/modules/`uname -r`/ubuntu/sound/ directory and replace it with a symbolic link to "../../kernel/sound/" where your new alsa-driver modules are stored.

[davidryderuk]

Thanks,
This works for me in Hardy as well with a Hi-grade computer and via vt1708 audio chip after following squil and gnuslov's instructions. Do you know if this fix going to make it into the unpatched version of alsa at some stage? (it took me about 6 months to find this fix, after i first started with Linux)
