When connecting headphones to line out (or other any output), I hear line output (not apmlified). I think, output to headphone must be amplified. ====================================================================== ---------------------------------------------------------------------- tiwai - 03-24-05 19:43 ---------------------------------------------------------------------- Attach the content of /proc/asound/card0/codec97#0/* files. Check the register 0x7a in /proc/asound/card0/codec97#0/ac97#0-0+regs. How are the bits 6 and 7? According to the datasheet, bit 7 corresponds to the Front-out amplifier control. When the driver is compiled with CONFIG_SND_DEBUG=y, you can edit the register value via this proc file, like # echo 7a 2092 > /proc/asound/card0/codec97#0/ac97#0-0+regs ---------------------------------------------------------------------- rlrevell - 01-12-06 04:21 ---------------------------------------------------------------------- No response Issue History Date Modified Username Field Change ====================================================================== 03-24-05 17:13 rmrfchik New Issue 03-24-05 17:13 rmrfchik Distribution => Debian 03-24-05 17:13 rmrfchik Kernel Version => 2.6.10-1 03-24-05 19:43 tiwai Note Added: 0004195 01-12-06 04:21 rlrevell Status new => closed 01-12-06 04:21 rlrevell Note Added: 0007580 ====================================================================== ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
