Olen palannut taas saman ongelman pariin.
Ilmeisesti näillä ohjeilla ongelman saisi korjattua:
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=snd_hda_codec_read(codec, 0x20, 0, AC_VERB_GET_CONFIG_DEFAULT, 0);
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);
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;
}
now, in order to compile :
cd alsa-driver-1.xx.xx
./configure
make
sudo make install
Reboot and that should work fine.
Ongelmana on se, että en varsinaisesti ymmärä tai osaa hyödyntää näitä ohjeita. Siis ei mulla ei esimerkiksi ole mitään alsa-kernel/pci/hda/patch_via.c-polkua. Osaatteko hieman auttaa tässä ongelmassani?
