I am using Fujitsu Siemens Amilo Li1705 laptop with VT8237A based chipset. I cannot get from external speakers when i plug them in to the laptop. Alsamixer controls are NOT muted.
I am currently using 2.6.24-21-generic and have Ubuntu 8.06 LTS installed on my laptop. By default i donot see the "Headphone" control in alsa-mixer and only the laptop's internal speakers work. I followed the procedure listed in
(http://ubuntuforums.org/archive/index.php/t-556217.html).
and managed to get the "headphones" control in alsamixer. and could get the sound by plugging in external speakers. But after reboot I can no longer get the sound from external speakers, but the internal speakers work as usual.
Output of aplay -l

Subdevice #0: subdevice #0
Subdevice #1: subdevice #1
** The subdevices section is funny since there should be just one subdevice and not 2
Output of dmesg | grep hda
[ 86.304650] hda-intel: IRQ timing workaround is activated for card #0. Suggest a bigger bdl_pos_adj.
I can confirm that the same problem occurs for 2.6.24-16-generic also. I was using Edgy before and had to use the same trick as in the above link to get the sound to work on it but never got this problem.
