alsa-1.0.8 builds fine now on my Xbox. However, when I load the alsa module (see below for my modules.d/alsa), no sound card is detected. It may be important to note that my XBox is a newer model (1.6). Reproducible: Always Steps to Reproduce: 1. ACCEPT_KEYWORDS="~x86" emerge alsa-driver 2. edit /etc/modules.d/alsa (see below), then run modules-update 3. /etc/init.d/alsasound start, or modprobe -v snd-card-0 Actual Results: When running /etc/init.d/alsasound start: * Loading ALSA modules... * Loading: snd-card-0... [ ok ] * ERROR: Failed to load necessary drivers [ ok ] * Restoring Mixer Levels... * No mixer config in /etc/asound.state, you have to unmute your card!

When building alsa-driver, you should have had ALSA_CARDS='intel8x0' in your make.conf. Is this the case?
Yes, I have ALSA_CARDS='intel8x0' in make.conf. The module is built and it loads just fine (see the lsmod output), it just does not detect the card.
Did you use "modprobe snd-intel8x0 xbox=1"? Alsa can't auto detect the xbox sound hw.
Yes. That is, I've put xbox=1 as option for the card in /etc/modules.d/alsa, which gets folded into /etc/modules.conf by modules-update. When I do (as shown above in the problem description): xbox root # modprobe -v snd-card-0 it says [other insmods] insmod /lib/modules/2.6.10-xbox/kernel/sound/pci/snd-intel8x0.ko xbox=1 So that should be the same, right?
That is the same (assuming you did modules-update before the modprobe).
Yes, I did run modules-update... Maybe this is helpful info: the following appears in /var/log/kernel/current each time I try to load the module: Feb 25 17:44:11 [kernel] PCI: Setting latency timer of device 0000:00:06.0 to 64 Feb 25 17:44:11 [kernel] ohci_hcd 0000:00:03.0: wakeup - Last output repeated 2 times - Feb 25 17:44:12 [kernel] Intel ICH: probe of 0000:00:06.0 failed with error -13 Feb 25 17:44:13 [kernel] ohci_hcd 0000:00:03.0: wakeup I don't know what to make of "error -13", but 0000:00:06.0 is the pci address of the audio device (it has two, for some reason?): xbox root # lspci | grep audio 0000:00:05.0 Multimedia audio controller: nVidia Corporation nForce Audio (rev d2) 0000:00:06.0 Multimedia audio controller: nVidia Corporation nForce Audio (rev d2) Any ideas, anyone?
Could be related to the "No sound in 2.6.10" thread on xbox-linux-user? http://sourceforge.net/mailarchive/message.php?msg_id=10500378
Thanks for the link Chris, you made my day! I changed (in sound/pci/ac97/ac97_codec.c): if (!(ac97->scaps & AC97_SCAP_SKIP_AUDIO) && !(ac97->scaps & AC97_SCAP_AUDIO)) { /* test if we can write to the record gain volume register */ snd_ac97_write_cache(ac97, AC97_REC_GAIN, 0x8a06); if (((err = snd_ac97_read(ac97, AC97_REC_GAIN)) & 0x7fff) == 0x0a06) ac97->scaps |= AC97_SCAP_AUDIO; } to if (!(ac97->scaps & AC97_SCAP_SKIP_AUDIO) && !(ac97->scaps & AC97_SCAP_$ if ((ac97->scaps & AC97_SCAP_DETECT_BY_VENDOR)) ac97->scaps |= AC97_SCAP_AUDIO; else { /* test if we can write to the record gain volume register */ snd_ac97_write_cache(ac97, AC97_REC_GAIN, 0x8a06); if (((err = snd_ac97_read(ac97, AC97_REC_GAIN)) & 0x7fff) == 0x$ ac97->scaps |= AC97_SCAP_AUDIO; } } And now it works! The intel_8x0 card is detected: xbox root # cat /proc/asound/cards 0 [nForce ]: NFORCE - NVidia nForce NVidia nForce with unknown codec at 0xfec00000, irq 6 My Xbox is playing through the stereo as I write this. :-D Could someone with more Gentoo-hacking experience than me convert this into a patch and add it to the alsa-driver ebuild?
I've emailed David Pye, I think maybe the fix never got sent upstream..
Searching the alsa bugs I found this: https://bugtrack.alsa-project.org/alsa-bug/view.php?id=778 Looks like the same bug.
That's because I submitted it... ;-) Too bad nobody reacted; there is a lot more activity here at bugs.gentoo.org (fortunately).
Oh, and that first line in the fixed version should read: if (!(ac97->scaps & AC97_SCAP_SKIP_AUDIO) && !(ac97->scaps & AC97_SCAP_AUDIO)) { (not AC97_SCAP_$, that's what you get when cutting/pasting from nano -w ;-)
Created attachment 53849 [details] Working version of sound/pci/ac97/ac97_codec.c
Thanks for that, I've added it to cvs. Re-open this bug if it doesn't work.
