 |
|
Hi,
I am forced to downgrade the kernel to 2.6.35 since my tv tuner card (PVR-500) works well with ivtv-1.41. Any kernel later than that has a later release of ivtv which gives me audio issues.
I was able to build the kernel using old gentoo-sources ebuild and genpatches. There are two issues I have.
1. The ownership of /dev/video* shows up as root:root instead of root:video.
| Code: |
Kernel 2.6.35
#ls -la /dev/video*
crw------- 1 root root 81, 0 Sep 18 00:33 /dev/video0
crw------- 1 root root 81, 5 Sep 18 00:33 /dev/video1
crw------- 1 root root 81, 9 Sep 18 00:33 /dev/video2
crw------- 1 root root 81, 3 Sep 18 00:33 /dev/video24
crw------- 1 root root 81, 8 Sep 18 00:33 /dev/video25
crw-rw---- 1 root video 81, 12 Sep 18 00:33 /dev/video26
crw-rw---- 1 root video 81, 17 Sep 18 00:33 /dev/video27
crw-rw---- 1 root video 81, 14 Sep 18 00:33 /dev/video3
crw------- 1 root root 81, 1 Sep 18 00:33 /dev/video32
crw------- 1 root root 81, 6 Sep 18 00:33 /dev/video33
crw------- 1 root root 81, 10 Sep 18 00:33 /dev/video34
crw-rw---- 1 root video 81, 15 Sep 18 00:33 /dev/video35
crw-rw---- 1 root video 81, 18 Sep 18 00:33 /dev/video4

In comparison kernel 3.10.7 shows the correct permissions and ownership which i want
| Code: |
Kernel 3.10.7
#ls -la /dev/video*
crw-rw---- 1 root video 81, 0 Sep 18 00:40 /dev/video0
crw-rw---- 1 root video 81, 5 Sep 18 00:40 /dev/video1
crw-rw---- 1 root video 81, 9 Sep 18 00:40 /dev/video2
crw-rw---- 1 root video 81, 3 Sep 18 00:40 /dev/video24
crw-rw---- 1 root video 81, 8 Sep 18 00:40 /dev/video25
crw-rw---- 1 root video 81, 12 Sep 18 00:40 /dev/video26
crw-rw---- 1 root video 81, 17 Sep 18 00:40 /dev/video27
crw-rw---- 1 root video 81, 14 Sep 18 00:40 /dev/video3
crw-rw---- 1 root video 81, 1 Sep 18 00:40 /dev/video32
crw-rw---- 1 root video 81, 6 Sep 18 00:40 /dev/video33
crw-rw---- 1 root video 81, 10 Sep 18 00:40 /dev/video34
crw-rw---- 1 root video 81, 15 Sep 18 00:40 /dev/video35
crw-rw---- 1 root video 81, 18 Sep 18 00:41 /dev/video4

2. The second problem i have is that with 2.6.35, the bootup is slow with lot of time taken by "Waiting for uevents to be processed..."
Any help will be much appreciated.
Thanks |

| Could you provide a link to the bug report about the audio issues seen with later versions? |
