Andersen" X-Mailer: ELM [version 2.5 PL3] MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG I've noticed a few posts earlier about people having little luck getting pcm to work with their thinkpads, but figured I'd throw in a bit of a question. I'm happy to guineapig potential solutions. Thinkpad T22 (1Ghz PIII) Crystal CS4297a Crystal CS4624 (I think) FreeBSD 4.3-release PCM is happy seeing the chip: csa0: mem 0xe8000000-0xe80fffff,0xe8122000-0xe8122fff irq 7 at device 5.0 on p ci0 pcm0: on csa0 When one attempts to play sounds to it using mpg123, the play completes almost instantly, and one receives the by-now familiar: pcm0: play interrupt timeout, channel dead This happens regardless of whether or not I use 'device csa' It doesn't seem to matter what IRQ I have the audio device on, though csa isn't happy on the default of 11. The opensound drivers for FreeBSD don't work properly, though they can get some very scratchy sounds to spit out. Any suggestions / thoughts / etc? Will hack or guinea pig for sound, though I haven't poked around with the sound code much. -Dave To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
