I'll try and answer your questions: > 1. the specific steps or actions you took that caused you to encounter the problem,
Fresh install of Ubuntu 12.04 LTS Memory 3.4GBytes Processor AMD A6-4400M APU with Radeon(tm) HD Graphics x 2 Graphics VESA: DVST OS type 32-bit Disk 305.0GByte HP Pavilion g6-2123us After the fresh Ubuntu install, I installed mozilla's Thunderbird and Firefox. > 2. the behavior you expected, and I was expecting the applications not to lock up. I was also expecting to be able to use sound when operating an HP g6-2123us booted up in Ubuntu. > 3. the behavior you actually encountered (in as much detail as possible). The Thunderbird and Firefox applications locked up during use. Thunderbird would usually lockup upon accessing the 1st email. Firefox locked up if right clicking on a URL in a web page. I might be mistaken, but I think if either application intended to use the audio hardware, they would lock up (the application's window would darken and the application's buttons would be unresponsive). Note, even if the application's buttons were unresponsive, the Ubuntu window buttons (kill, minimize & full-screen) were usable. If one clicked on the Ubuntu kill button a pop up would appear saying the application was unresponsive and asked if the application should be forcefully killed. ------------ Further information: The /var/log/syslog was inspected. It appears that the pulseaudio daemon failed to start on boot up: --- Jul 13 15:24:05 frodo kernel: [ 8335.295591] Process pulseaudio (pid: 4898, ti=e9df0000 task=e1c0bf20 task.ti=e9df0000) Jul 13 15:24:05 frodo kernel: [ 8335.295594] Stack: Jul 13 15:24:05 frodo kernel: [ 8335.295597] 00000010 000240d0 eb78c180 e9f35c00 e9df1d14 f8793de2 00000080 e9f35c00 Jul 13 15:24:05 frodo kernel: [ 8335.295610] ebb2a100 e9df1d14 f87003b7 e9f35c00 00000000 eb7de000 00000000 eb0a4e2c Jul 13 15:24:05 frodo kernel: [ 8335.295622] eb78c180 e9f35c00 eb7dc24c e9df1d40 f86e9b73 00000080 f7132238 eb78c180 Jul 13 15:24:05 frodo kernel: [ 8335.295633] Call Trace: Jul 13 15:24:05 frodo kernel: [ 8335.295642] [<f8793de2>] hdmi_pcm_open+0x32/0x210 [snd_hda_codec_hdmi] Jul 13 15:24:05 frodo kernel: [ 8335.295657] [<f87003b7>] ? snd_pcm_hw_constraint_step+0x37/0x40 [snd_pcm] Jul 13 15:24:05 frodo kernel: [ 8335.295666] [<f86e9b73>] azx_pcm_open+0x1d3/0x280 [snd_hda_intel] Jul 13 15:24:05 frodo kernel: [ 8335.295678] [<f86fee93>] snd_pcm_open_substream+0x53/0x90 [snd_pcm] Jul 13 15:24:05 frodo kernel: [ 8335.295689] [<f86fef8a>] snd_pcm_open+0xba/0x240 [snd_pcm] Jul 13 15:24:05 frodo kernel: [ 8335.295699] [<c1053fe0>] ? try_to_wake_up+0x190/0x190 Jul 13 15:24:05 frodo kernel: [ 8335.295710] [<f8cc8044>] ? snd_lookup_minor_data+0x44/0x60 [snd] Jul 13 15:24:05 frodo kernel: [ 8335.295722] [<f86ff19b>] snd_pcm_playback_open+0x3b/0x50 [snd_pcm] Jul 13 15:24:05 frodo kernel: [ 8335.295733] [<f8cc8544>] snd_open+0xd4/0x260 [snd] Jul 13 15:24:05 frodo kernel: [ 8335.295740] [<c1386d6c>] ? kobj_lookup+0xfc/0x1a0 Jul 13 15:24:05 frodo kernel: [ 8335.295748] [<c1148765>] chrdev_open+0xb5/0x1e0 Jul 13 15:24:05 frodo kernel: [ 8335.295757] [<c11427de>] __dentry_open+0x25e/0x310 Jul 13 15:24:05 frodo kernel: [ 8335.295763] [<c11486b0>] ? cdev_put+0x20/0x20 Jul 13 15:24:05 frodo kernel: [ 8335.295769] [<c1142d5a>] vfs_open+0x3a/0x50 Jul 13 15:24:05 frodo kernel: [ 8335.295775] [<c1143c59>] nameidata_to_filp+0x39/0x40 Jul 13 15:24:05 frodo kernel: [ 8335.295782] [<c11510b7>] do_last+0x367/0x660 Jul 13 15:24:05 frodo kernel: [ 8335.295787] [<c11523e4>] path_openat+0xa4/0x350 Jul 13 15:24:05 frodo kernel: [ 8335.295794] [<c117c084>] ? fsnotify_put_event+0x44/0x60 Jul 13 15:24:05 frodo kernel: [ 8335.295800] [<c117c084>] ? fsnotify_put_event+0x44/0x60 Jul 13 15:24:05 frodo kernel: [ 8335.295806] [<c11527a1>] do_filp_open+0x31/0x80 Jul 13 15:24:05 frodo kernel: [ 8335.295814] [<c12b7958>] ? strncpy_from_user+0x38/0x70 Jul 13 15:24:05 frodo kernel: [ 8335.295820] [<c115dd13>] ? alloc_fd+0xa3/0xe0 Jul 13 15:24:05 frodo kernel: [ 8335.295826] [<c1143d41>] do_sys_open+0xe1/0x1f0 Jul 13 15:24:05 frodo kernel: [ 8335.295839] [<f8ccd390>] ? snd_ctl_elem_add_user+0x70/0x70 [snd] Jul 13 15:24:05 frodo kernel: [ 8335.295846] [<c1143e7e>] sys_open+0x2e/0x40 Jul 13 15:24:05 frodo kernel: [ 8335.295854] [<c15ac69f>] sysenter_do_call+0x12/0x28 Jul 13 15:24:05 frodo kernel: [ 8335.295857] Code: 8d b6 00 00 00 00 0f b7 16 83 e8 02 83 c6 02 66 89 17 83 c7 02 eb 9f 8d b4 26 00 00 00 00 55 89 e5 56 53 83 ec 08 3e 8d 74 26 00 <8b> b0 84 00 00 00 89 c1 85 f6 7e 2b 8d 98 2c 0e 00 00 31 c0 39 Jul 13 15:24:05 frodo kernel: [ 8335.295929] EIP: [<f8793c5d>] hinfo_to_pin_index+0xd/0x60 [snd_hda_codec_hdmi] SS:ESP 0068:e9df1cc8 Jul 13 15:24:05 frodo kernel: [ 8335.295939] CR2: 0000000000000084 Jul 13 15:24:05 frodo kernel: [ 8335.295944] ---[ end trace 698f71d3b8b827c9 ]--- Jul 13 15:24:05 frodo pulseaudio[4895]: [pulseaudio] main.c: Daemon startup failed. --- Here is a list of audio devices on the PCI bus: lspci | grep -i audio 00:01.1 Audio device: Advanced Micro Devices [AMD] nee ATI Device 9902 00:14.2 Audio device: Advanced Micro Devices [AMD] Hudson Azalia Controller (rev 01) Now I am thinking this audio hardware in the newly released HP g6-2123us is too new for pulseaudio to successfully start. But even if the pulseaudio daemon failed, I find it hard to believe that Thunderbird and/or Firefox should suffer an application lock up using the Ubuntu default desktop. Note: After un-installing the pulse audio package, I can run Thunderbird and Mozilla for hours and not suffer a lock up. Of course there is no sound on the HP g6-2123us laptop when booted up in Ubuntu. --- Lastly, I ran the alsa script (alsa-info.sh). The output is lengthy.
