Subject: [PATCH] Sound recording with OPL3SA2
Date: Sun, 15 Jul 2001 12:13:32 +0000 [thread overview]
Message-ID: <marc-linux-sound-99519931815581@msgid-missing> (raw)
Hi.
I got this message in the log when I tried to do sound recording:
"Sound: DMA (input) timed out - IRQ/DRQ config error?"
After some investigations I found a bug in the opl3sa2 driver. I have
sent this patch to Scott Murray (scott@spiteful.org), but received no
answer. And the bug is still in kernel 2.4.6.
So now I escalate the issue to the linux-sound mailing list....
In the attach_opl3sa2() function we look at the dma values to see if we
are using two or one channel, and configure the chip accordingly.
Unfortunately the dma values are not set in the structure we look at.
Please CC any comments to me, ljoas@yahoo.com, thanks.
