Hello,
Since last week I compiled 2.6.38 on my Desktop. After booting I noticed a regression at the sound stuff. The surround speaker where no longer controlled by the master volume control. I can control it separately, but not with the master control that controls the front, center and LFE volume.
After some debugging I found some differencies at module-loading output in the kernel log and in the output from alsactl store command. The dmesg and the diff of the alsactl output can be found at the end of this message.
After that I tried to understand the hda-codec code and debugged there with a lot of printks and reboots. It takes another couple of hours to find out that the index of the surround volume and switch was 0 at pre 2.6.38 and is now 1. So I wrote a dirty hack to fix this (please ignore the debugging printks):
diff --git a/pci/hda/hda_codec.c b/pci/hda/hda_codec.c index ae5c5d5..d3fd6d2 100644 --- a/pci/hda/hda_codec.c +++ b/pci/hda/hda_codec.c @@ -3819,7 +3819,16 @@ int snd_hda_add_new_ctls(struct hda_codec *codec, struct snd_kcontrol_new *knew) kctl->id.device = addr; if (idx > 0) kctl->id.index = idx; + + snd_printk(KERN_INFO "PRE snd_hda_ctl_add - addr = %d, idx = %d, kctl->id.name = %s, kctl->id.index = %d, kctl->id.device = %d, kctl->count = %d", + addr, idx, kctl->id.name, kctl->id.index, kctl->id.device, kctl->count); err = snd_hda_ctl_add(codec, 0, kctl); + snd_printk(KERN_INFO "PASSED snd_hda_ctl_add - err = %d, addr = %d, idx = %d, kctl->id.name = %s, kctl->id.index = %d, kctl->id.device = %d, kctl->count = %d", + err, addr, idx, kctl->id.name, kctl->id.index, kctl->id.device, kctl->count); + if (strncmp("Surround Playback Switch", kctl->id.name, strlen("Surround Playback Switch"))) + kctl->id.index = 0; + if (strncmp("Surround Playback Volume", kctl->id.name, strlen("Surround Playback Volume"))) + kctl->id.index = 0; if (!err) break; /* try first with another device index corresponding to
At all I dont understand what I've exactly done. I also know that this is not a real solution, because it will break the code for many other plattforms. So I hope someone can convert this to a real fix cor can guide me to make such one.
The platform is a ASUS M4A89GTD-PRO/USB3 Board. If any further information needed, please tell me.
Thanks, Jan Losinski
