Hello, |
| 2 |
|
| 3 |
I have been trying get the right combination of kernel modules selected |
| 4 |
for building a kernel that allows me to select the output and input |
| 5 |
hardware via kmix. The machine laptop has an onboard frame grabber: |
| 6 |
|
| 7 |
lspci: |
| 8 |
02:04.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11) |
| 9 |
00:1f.5 Multimedia audio controller: Intel Corporation 82801CA/CAM AC'97 Audio |
| 10 |
Controller (rev 02) |
| 11 |
|
| 12 |
Kmix shows these options for "Current Mixer" |
| 13 |
Intel 82801CA-ICH3 |
| 14 |
Intel 82801CA-ICH3 Modem |
| 15 |
|
| 16 |
With these selections for Sound drivers in the 2.6.14.gentoo.r4 kernel are |
| 17 |
used: |
| 18 |
# Sound |
| 19 |
CONFIG_SOUND=y |
| 20 |
# Advanced Linux Sound Architecture |
| 21 |
CONFIG_SND=y |
| 22 |
CONFIG_SND_TIMER=y |
| 23 |
CONFIG_SND_PCM=y |
| 24 |
CONFIG_SND_SEQUENCER=y |
| 25 |
CONFIG_SND_SEQ_DUMMY=y |
| 26 |
CONFIG_SND_OSSEMUL=y |
| 27 |
CONFIG_SND_MIXER_OSS=y |
| 28 |
CONFIG_SND_PCM_OSS=y |
| 29 |
CONFIG_SND_SEQUENCER_OSS=y |
| 30 |
CONFIG_SND_VERBOSE_PRINTK=y |
| 31 |
CONFIG_SND_DEBUG=y |
| 32 |
CONFIG_SND_DEBUG_MEMORY=y |
| 33 |
CONFIG_SND_DEBUG_DETECT=y |
| 34 |
# ISA devices |
| 35 |
CONFIG_SND_AC97_ |
| 36 |
CONFIG_SND_AC97_BUS=y |
| 37 |
# PCI devices |
| 38 |
CONFIG_SND_BT87X=y |
| 39 |
CONFIG_SND_BT87X_OVERCLOCK=y |
| 40 |
CONFIG_SND_INTEL8X0=y |
| 41 |
CONFIG_SND_INTEL8X0M=y |
| 42 |
CONFIG_SND_HDA_INTEL=y |
| 43 |
# Open Sound System |
| 44 |
CONFIG_SOUND_PRIME=y |
| 45 |
CONFIG_SOUND_BT878=y |
| 46 |
|
| 47 |
However with a '2.6.12-gentoo-r10' kernel I Kmix shows the correct choice |
| 48 |
between the intel device and the BT878 device options for "Current Mixer". |
| 49 |
|
| 50 |
Here are the settings for the 2.6.12-gentoo-r10 kernel which correctly |
| 51 |
shows the bt878 and the intel hardware: |
| 52 |
# Sound |
| 53 |
CONFIG_SOUND=y |
| 54 |
# Advanced Linux Sound Architecture |
| 55 |
CONFIG_SND=y |
| 56 |
CONFIG_SND_TIMER=y |
| 57 |
CONFIG_SND_PCM=y |
| 58 |
CONFIG_SND_SEQUENCER=y |
| 59 |
# CONFIG_SND_SEQ_DUMMY is not set |
| 60 |
CONFIG_SND_OSSEMUL=y |
| 61 |
CONFIG_SND_MIXER_OSS=y |
| 62 |
CONFIG_SND_PCM_OSS=y |
| 63 |
CONFIG_SND_SEQUENCER_OSS=y |
| 64 |
# CONFIG_SND_VERBOSE_PRINTK is not set |
| 65 |
# CONFIG_SND_DEBUG is not set |
| 66 |
# PCI devices |
| 67 |
CONFIG_SND_AC97_CODEC=y |
| 68 |
CONFIG_SND_BT87X=y |
| 69 |
CONFIG_SND_BT87X_OVERCLOCK=y |
| 70 |
CONFIG_SND_INTEL8X0=y |
| 71 |
# Open Sound System |
| 72 |
CONFIG_SOUND_PRIME=y |
| 73 |
CONFIG_SOUND_BT878=y |
| 74 |
|
| 75 |
|
| 76 |
The obvious differences in the /usr/src/linux/.config files for the |
| 77 |
2.6.14-r4 and the 1.6.12.r10 have been modified for every conceivable |
| 78 |
combination, including exactly identical, yet I cannot get the |
| 79 |
"Current mixer" options in 2.6.14 to make those of 2.6.12.... |
| 80 |
|
| 81 |
This issue is on the same |
| 82 |
laptop, not different laptops and all other configs are the same, so |
| 83 |
it must be in how the kernel is configured. I even directly editing |
| 84 |
the /usr/src/linux/.config file directly so as to not make a mistake |
| 85 |
via make menuconfig. After making modifications to the /usr/src/linux/.config |
| 86 |
file I run these commands (from /usr/src/linux): |
| 87 |
|
| 88 |
make && make modules_install |
| 89 |
cp .config /boot/config-2.6.14-gentoo-r4 |
| 90 |
cp System.map /boot/System.map-2.6.14-gentoo-r4 |
| 91 |
cp arch/i386/boot/bzImage /boot/kernel-2.6.14-gentoo-r4 |
| 92 |
reboot <and test> |
| 93 |
|
| 94 |
Thoughts and ideas are most appreciated. |
