Hey guys, i've been trying unsuccessfully for 2 days to configure surround sound in my ubuntu server. I started with just alsa and it didn't work. now I installed pulseaudio but it didn't work either. I know the driver supports it because when i boot from an ubuntu-desktop live cd it works, but I haven't been able to reproduce it in my real system. here is my configuration http://www.alsa-project.org/db/?f=1ccb91eae73ccb96ce3ae646869a22a5bb2734cd the soundcard is integrated in a p5g4ic-m asus mobo i tried running the same script when it does work and finding the diffs in the output. I managed to make everything the same except the kernel modules running obviously but it still doesn't work this is the diff hilikus@hilikus-pc:~/tmp$ diff -u alsa-info-mazinger-with-pulse live_cd --- alsa-info-mazinger-with-pulse 2011-01-08 14:57:32.000000000 -0500 +++ live_cd 2011-01-07 20:37:04.000000000 -0500 @@ -1,9 +1,9 @@ -upload=true&script=true&cardinfo= + !!################################ !!ALSA Information Script v 0.4.59 !!################################ -!!Script ran on: Sat Jan 8 19:57:27 UTC 2011 +!!Script ran on: Sat Jan 8 01:32:53 UTC 2011 !!Linux Distribution @@ -22,7 +22,7 @@ !!Kernel Information !!------------------ -Kernel release: 2.6.35-24-generic-pae +Kernel release: 2.6.35-22-generic Operating System: GNU/Linux Architecture: i686 Processor: unknown @@ -520,20 +520,20 @@ !!ALSA Device nodes !!----------------- -crw-rw----+ 1 root audio 116, 9 Jan 8 14:25 /dev/snd/controlC0 -crw-rw----+ 1 root audio 116, 8 Jan 8 14:25 /dev/snd/hwC0D0 -crw-rw----+ 1 root audio 116, 7 Jan 8 14:26 /dev/snd/pcmC0D0c -crw-rw----+ 1 root audio 116, 6 Jan 8 14:32 /dev/snd/pcmC0D0p -crw-rw----+ 1 root audio 116, 5 Jan 8 14:26 /dev/snd/pcmC0D1p -crw-rw----+ 1 root audio 116, 4 Jan 8 14:25 /dev/snd/pcmC0D2c -crw-rw----+ 1 root audio 116, 3 Jan 8 14:25 /dev/snd/seq -crw-rw----+ 1 root audio 116, 2 Jan 8 14:25 /dev/snd/timer +crw-rw---- 1 root audio 116, 9 Jan 8 01:22 /dev/snd/controlC0 +crw-rw---- 1 root audio 116, 8 Jan 8 01:22 /dev/snd/hwC0D0 +crw-rw---- 1 root audio 116, 7 Jan 8 01:28 /dev/snd/pcmC0D0c +crw-rw---- 1 root audio 116, 6 Jan 8 01:32 /dev/snd/pcmC0D0p +crw-rw---- 1 root audio 116, 5 Jan 8 01:23 /dev/snd/pcmC0D1p +crw-rw---- 1 root audio 116, 4 Jan 8 01:22 /dev/snd/pcmC0D2c +crw-rw---- 1 root audio 116, 3 Jan 8 01:22 /dev/snd/seq +crw-rw---- 1 root audio 116, 2 Jan 8 01:22 /dev/snd/timer /dev/snd/by-path: total 0 -drwxr-xr-x 2 root root 60 Jan 8 14:25 . -drwxr-xr-x 3 root root 220 Jan 8 14:25 .. -lrwxrwxrwx 1 root root 12 Jan 8 14:25 pci-0000:00:1b.0 -> ../controlC0 +drwxr-xr-x 2 root root 60 Jan 8 01:22 . +drwxr-xr-x 3 root root 220 Jan 8 01:22 .. +lrwxrwxrwx 1 root root 12 Jan 8 01:22 pci-0000:00:1b.0 -> ../controlC0 !!Aplay/Arecord output @@ -928,72 +928,60 @@ !!------------------ Module -lirc_zilog -lirc_dev +binfmt_misc +parport_pc +ppdev +lp +parport +dm_crypt snd_hda_codec_realtek -xfs -exportfs -nvidia snd_hda_intel snd_hda_codec snd_hwdep snd_pcm +tuner_simple +tuner_types snd_seq_midi snd_rawmidi +wm8775 snd_seq_midi_event snd_seq -snd_timer -snd_seq_device -ipt_REJECT -xt_recent -xt_comment -ipt_LOG -xt_multiport -xt_limit -xt_tcpudp -ipt_addrtype -xt_state -tuner_simple -tuner_types -wm8775 tuner cx25840 -ip6table_filter -ip6_tables -nf_nat_irc -nf_conntrack_irc -nf_nat_ftp -nf_nat -nf_conntrack_ipv4 -nf_defrag_ipv4 -nf_conntrack_ftp -nf_conntrack -iptable_filter -asb100 -hwmon_vid -ip_tables +snd_timer +snd_seq_device ivtv -snd -x_tables -i2c_viapro -i2c_algo_bit cx2341x -asus_atk0110 +snd v4l2_common -intel_agp videodev +asus_atk0110 +led_class v4l1_compat tveeprom -led_class soundcore -lp snd_page_alloc -agpgart -parport +squashfs +aufs +nls_cp437 +isofs +dm_raid45 +xor +btrfs +zlib_deflate +crc32c +libcrc32c usbhid hid +nouveau +ttm +drm_kms_helper +drm r8169 +intel_agp mii +agpgart +i2c_algo_bit !!Sysfs Files @@ -1025,20 +1013,19 @@ !!ALSA/HDA dmesg !!------------------ -[ 9.735593] alloc kstat_irqs on node -1 -[ 9.735599] HDA Intel 0000:00:1b.0: PCI INT A -> GSI 21 (level, low) -> IRQ 21 -[ 9.735636] alloc irq_desc for 44 on node -1 -[ 9.735638] alloc kstat_irqs on node -1 -[ 9.735645] HDA Intel 0000:00:1b.0: irq 44 for MSI/MSI-X -[ 9.735666] HDA Intel 0000:00:1b.0: setting latency timer to 64 -[ 9.941206] r8169 0000:02:00.0: eth0: link up --- -[ 12.264636] Ending clean XFS mount for filesystem: sda4 -[ 12.816512] hda-intel: azx_get_response timeout, switching to polling mode: last cmd=0x100f0000 -[ 13.820503] hda-intel: No response from codec, disabling MSI: last cmd=0x100f0000 -[ 14.715870] cx25840 0-0044: loaded v4l-cx25840.fw firmware (16382 bytes) -[ 14.824510] hda-intel: Codec #1 probe error;
