I am trying to get an SBLive soundcard which I have recently installed to work. I have a Gigabyte motherboard (NForce4) with onboard sound (AC97) which I have disabled. The SBLive has been used by me in another machine and works fine.
All the correct modules seem to load:
$ lsmod | grep snd snd_seq_oss 33408 0 snd_seq_midi_event 6400 1 snd_seq_oss snd_seq 51984 4 snd_seq_oss,snd_seq_midi_event snd_pcm_oss 50848 0 snd_mixer_oss 17920 1 snd_pcm_oss snd_emu10k1 121892 0 snd_rawmidi 21152 1 snd_emu10k1 snd_ac97_codec 95136 1 snd_emu10k1 snd_ac97_bus 2176 1 snd_ac97_codec snd_pcm 84100 3 snd_pcm_oss,snd_emu10k1,snd_ac97_codec snd_seq_device 7436 4 snd_seq_oss,snd_seq,snd_emu10k1,snd_rawmidi snd_timer 22148 3 snd_seq,snd_emu10k1,snd_pcm snd_page_alloc 8840 2 snd_emu10k1,snd_pcm snd_util_mem 3840 1 snd_emu10k1 snd_hwdep 7712 1 snd_emu10k1 snd 49124 11 snd_seq_oss,snd_seq,snd_pcm_oss,snd_mixer_oss, snd_emu10k1,snd_rawmidi,snd_ac97_codec,snd_pcm,snd_seq_device,snd_timer,snd_hwdep soundcore 8160 1 snd
But there is nothing in /proc:
$ cat /proc/asound/cards --- no soundcards ---
Alsamixer bombs out with a unsurprising (in light of above) error:
$ alsamixer alsamixer: function snd_ctl_open failed for default: No such device
lspci shows the device:
$ /usr/sbin/lspci -v | grep -i audio 01:07.0 Multimedia audio controller: Creative Labs SB Live! EMU10k1 (rev 05)
The wierd thing is that when I first installed it, I got these same sort of errors and symptoms, but then I updated the system with pacman, getting the latest udev (087-1) and kernel (18.104.22.168-2), after which I rebooted, and got sound! There was a /proc/asound/card0 entry, tested xmms and Doom3, all was fine. But a subsequent reboot resulted in the above symptoms again, and I have rebooted about 3 or 4 times since then (just in case!), but with no joy.
I have tried running /etc/start_udev with no result. I have also tried both forcing snd_emu10k1 in /etc/rc.conf, and disabling it and manually loading it later.
I was wondering if there is something basic I am neglecting?
Any ideas anyone?
Thanks in advance,
I've managed to nail this one (I hope - I'll be checking /proc/asound/cards for several reboots now!)
A recurring entry in /var/log/kernel.log aroused my suspicion:
Mar 15 16:12:22 aquilonia ACPI: PCI interrupt for device 0000:01:07.0 disabled Mar 15 16:12:22 aquilonia EMU10K1_Audigy: probe of 0000:01:07.0 failed with error -5
Which prompted me to move the soundcard to another PCI slot. Now when I `cat /proc/asound/cards`, I get:
0 [Live ]: EMU10K1 - SBLive! Platinum [CT4760P] SBLive! Platinum [CT4760P] (rev.5, serial:0x80401102) at 0xc000, irq 17
Sound now works (xmms is streaming from WickedKarma as I type 8) ), and it's survived two reboots so far!
I hope this helps anyone else who has a similar issue.
