[em28xx] No sound in Leadtek WinFast TV USB II (not Deluxe)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello.

I try to plug  Leadtek WinFast TV USB II (LR6021 Rev. C) to my Ubuntu
10.04 (2.6.32-22-generic #33-Ubuntu SMP Wed Apr 28 13:27:30 UTC 2010
i686 GNU/Linux with all latest security and updates ). First I try
card=8 - no results, then I try card=28 (because in Windows it seems
like Leadtek WinFast TV USB II Deluxe) - TV works fine, tvtime scans
all available channels, but no sound in any audio standards
(/dev/mixer:line1 is ok with other sources). If I start tuner in
Windows, make hard reset, boot Ubuntu and start tvtime then audio
works fine at all channels while tuner is powered on. So I think
em28xx doesn't execute some initializing sequence for turn on audio.

With latest version from http://linuxtv.org/hg/v4l-dvb my tuner works
only if i change SAA7115_COMPOSITE4 to SAA7115_COMPOSITE2 in
EM28XX_VMUX_TELEVISION section for Leadtek WinFast TV USB II Deluxe in
em28xx-cards.c and only video too. /dev/radio detected but not work
too.

Any tips, recommendations? I don't want use Windows to tuner init only :)

The peace of dmesg when I don't set card:
