Public bug reported: On Ubuntu newer than 7.10, my Thinkpad X31 pauses ca. 2 min at boot, and than there is no sound at all.
I have tested Kubuntu 8.04, 8.04.2, 8.10 -> with all clean installs and updates the same problem. If i install an old Kernel, everything works fine, at least in Kubuntu 8.04.2. The last working kernel, i can get through the ubuntu repositorys is 2.6.22-15 (generic). I have collected some Informations about the sound chip on the working system (kernel 2.6.22-15): $ cat /proc/asound/cards 0 [I82801DBICH4 ]: ICH4 - Intel 82801DB-ICH4 Intel 82801DB-ICH4 with AD1981B at irq 11 $ lsmod | grep snd snd_intel8x0 34972 2 snd_ac97_codec 100644 1 snd_intel8x0 ac97_bus 3200 1 snd_ac97_codec snd_pcm_oss 44672 0 snd_pcm 80388 3 snd_intel8x0,snd_ac97_codec,snd_pcm_oss snd_mixer_oss 17664 1 snd_pcm_oss snd_seq_dummy 4740 0 snd_seq_oss 33152 0 snd_seq_midi 9600 0 snd_rawmidi 25728 1 snd_seq_midi snd_seq_midi_event 8448 2 snd_seq_oss,snd_seq_midi snd_seq 53232 6 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_seq_midi_event snd_timer 24324 2 snd_pcm,snd_seq snd_seq_device 9228 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_rawmidi,snd_seq snd 54660 14 snd_intel8x0,snd_ac97_codec,snd_pcm_oss,snd_pcm,snd_mixer_oss,snd_seq_oss,snd_rawmidi,snd_seq,snd_timer,snd_seq_device soundcore 8800 1 snd snd_page_alloc 11400 2 snd_intel8x0,snd_pcm The utils_alsa-info.sh script has uploaded its result at http://www.alsa-project.org/db/?f=61aa8f55ed0cfa5cd7a1a6c7b75d0d3660d64d28 I will attach the output of dmesg with the old kernel and with the new kernel. I will also attach the output of lspci, it is the same for the old and every new kernel, I've tested. ** Affects: ubuntu Importance: Undecided Status: New -- since Kernel 2.6.24 ubuntu pauses at boot + no sound on Thinkpad X31 https://bugs.launchpad.net/bugs/335207 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
