Remaining issue: Same tracks were clean when this board used 16-bit I2S/DAC and the same PPC3 table With 32-bit I2S + 0x33=0x03, silence and quiet passages are clean ; grain/sand appears only when the program has energy Source format is not the limiter: mixer already delivers 32-bit PCM; a silent file in PLAY has no grain Questions: Is the existing PPC3 export valid for 32-bit I2S playback , or must we re-export End System Integration with I2S word length = 32-bit? If the current table can stay, what else is required so 32-bit I2S sounds like the old 16-bit I2S path (other SAP bits, BCK polarity, DSP input format)? Please give the exact register sequence you recommend for: 48 kHz / 32-bit I2S / 64×fs + keep this PPC3, without audible grain on program. Thank you.TAS5805Mhttps://e2echina.ti.com/support/audio/f/audio-forum/1095034/tas5832evm-doc-cert-unable-to-install-tas5830-app-in-purepath-console-3/3942363Fri, 18 Sep 2026 01:29:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:a4b8e054-58ce-4454-8706-612e2088bc4fDaniel您好 TAS5828M: PurePath™︎ Console 3 GUI中不显示新申请的TAS5828M和TAS5825的EVM APP 请您参考这个说明。https://e2echina.ti.com/support/audio/f/audio-forum/1095034/tas5832evm-doc-cert-unable-to-install-tas5830-app-in-purepath-console-3/3942315Fri, 18 Sep 2026 00:22:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:d968e56d-ce47-4f01-bc71-478e4ff3e982Vivian GaoThank you for your attention to TI products.

Since TAS5830 is not available in the TI Device/Part Number selection list, I selected TAS5832EVM-DOC-CERT only in order to submit this support request. I am trying to install the TAS5830 EVM App in PurePath Console 3 (PPC3) . The TAS5830 App appears under “Available EVM Apps,” but the installation always fails. PPC3 reports the following error: “Problems occurred during installation of TAS5830. Refresh Available EVM Apps before trying again.” I have refreshed the Available EVM Apps and retried the installation many times , but the same error occurs every time. I have also restarted PPC3 and attempted the installation again, but the issue still persists. Could you please help confirm whether this issue is related to my TI account permissions , the TAS5830 App package , or my PPC3 installation/version ? Screenshots of the issue are attached for reference. Thank you for your support.TAS5832EVM-DOC-CERTTAS5830https://e2echina.ti.com/support/audio/f/audio-forum/1094086/pcm1681-q1-evm-sch-request/3939670Tue, 15 Sep 2026 04:24:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:c9e56f9a-ec40-46ff-99e9-402666a74fbdVivian Gao之前有过回复。 e2e.ti.com/.../pcm1681-q1-dem-pcm1681https://e2echina.ti.com/support/audio/f/audio-forum/1093844/tas5825m-tas5825m/3939062Mon, 14 Sep 2026 01:10:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:18aade57-8209-4ced-8cea-d02eeb57ec9aDaniel您好 您之前说明一起运行无法实现通信，您有没有尝试单个运行的结果如何?https://e2echina.ti.com/support/audio/f/audio-forum/1093844/tas5825m-tas5825m/3937930Fri, 11 Sep 2026 09:59:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:b8798148-7af5-46cf-b1f1-d1b9d49379e5shangu yun您好，现在的情况是断电重启后MCU发IIC指令给TAS5825M,但是tas5825m并无返回任何指令信息，通道运行不了https://e2echina.ti.com/support/audio/f/audio-forum/1094086/pcm1681-q1-evm-sch-request/3937910Fri, 11 Sep 2026 06:46:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:71c56586-bbbf-4b8c-871b-d3e4cb1ba83eDaniel您好 已经收到了您的案例，调查需要些时间，感谢您的耐心等待https://e2echina.ti.com/support/audio/f/audio-forum/1094086/pcm1681-q1-evm-sch-requestFri, 11 Sep 2026 06:24:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:6a2b6314-e132-4bc1-9177-60ce019f1a02Peng ZhangPart Number: PCM1681-Q1 Other Parts Discussed in Thread: PCM1681 Hi TEam, TYW need to use PCM1681 as truck audio, and want to reference our EVM to help design, pls help support me with the EVM sch and PCB design files, thanks!

We have performed swap‑test on OPA2134UA/2K5 under identical hardware setup. Units from June‑2024 wafer meet datasheet input‑bias‑current spec, while samples from post‑Sep‑2024 wafer show much higher input bias current. PCB and test fixture error have been ruled out. This issue is impacting our customer project timeline. Could you please help prioritize this investigation? Looking forward to your technical feedback.
