esssound.o once more

[Evgeny Polyakov]

Hello.

Some days ago problem with compiling esssound driver was erised.
And Alan Cox sad that in his -ac1 path this problem was solved, but....

Here is messages, that was occured while 2.4.7-ac9 was compiling:

drivers/sound/sounddrivers.o: In function `solo1_update_ptr':
drivers/sound/sounddrivers.o(.text+0xd6e): undefined reference to `clear_advance'
drivers/sound/sounddrivers.o: In function `solo1_write':

drivers/sound/sounddrivers.o(.text+0x2b05): undefined reference to `prog_dmabuf_dac'
drivers/sound/sounddrivers.o(.text+0x2c38): more undefined references to `prog_dmabuf_dac' fol

And in -ac1 this messages appear once more.
But( I don't know how can I do this) I had compiled 2.4.7-ac1 some days ago with esssound support:
Linux Sombre.2ka.mipt.ru 2.4.7-ac1 #4 Fri Jul 27 06:17:13 MSD 2001 i686 unknown

but after it i can't do this once more.

Any suggestions, help and advices are wellcome :).
