Thank you for the info regarding the patch. Rather than defensively assign the input monitor control (SOUND_MIXER_MONITOR) to an output, it'd be better to use a separate output control, eg add a control for SOUND_MIXER_OGAIN, should it actually be necessary.

A similar patch to Oleg's submission for the AD1980 might be applicable, but that's not in the tree today (still thinking about some general issues arising relating to this). As a potential short term fix you might check that moving the monitor gain right up doesn't improve the situation.

Re: VIA8235 + AD1980
Oleg Well done on working out a working fix for this problem and apologies for not answering the email you sent earlier. It was one of several lost in the inbox overflow whilst the recipient was busy elsewhere. I'm also going to be offline until until July 7th and won't be able to provide any further input for a little while. There are some comments inline below that may help. - Orion Oleg Sharoiko writes: | | There is a small problem with this patch: AC97_MIXEXT_SURROUND has | seprate mute bits for right and left channels and I don't see how | can they be implemented in FreeBSD.

Unfortunately I don't | have via8235 spec. Myabe data are being put into wrong timeslots? The driver was written from the VT8233 spec under NDA. The driver sets the AC97 slots for the multichannel register set - these are set with the macros SLOT3 and SLOT4. There are no documented registers for assigning the regular stereo playback channels to different slots. The behaviour you are describing would be partially explained if channel spreading were enabled in the codec (2 channels spread to 6). This can be manually and automatically enabled (AD1980 rev 0 specs pages 25 and 27). Since the AD1980 is an ac97 2.3 codec and these codecs do jack sense detection, it's probably worth checking out the ac97 2.3 spec and writing some code to find out what the jack sense registers report as attached. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]

bus_space_alloc (formerly bus_space_foo)
Hi I've been writing a driver for the S3 Sonicvibes audio card. The card is PCI, but has 7 io ports. The PCI initialization stops after 5 ports have been mapped out (constants are hardcoded in sys/pci so reasonable to assume this fits with PCI spec). The netbsd version of this driver uses bus_space_alloc to deal with the other two ports, but that function never made it from NetBSD to FreeBSD. Is there a workaround or equivalent? Or a driver that deals with the same problem? [ What the code does just now is examine the initial 5 io port allocations and then pick 2 non-overlapping port spaces between them for the unallocated ports. This is gross, but works for the time being (likely not future proof, but assumptions could be hardcoded to prevent driver loading if not met). A snapshot of the driver is at http://www.cs.ucl.ac.uk/staff/O.Hodson/misc/s3vibes.c - playback works, recording maybe, XXX marks the spot of resource fun. Feedback appreciated. ] Kind Regards - Orion. To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
